The Brief

As more and more Americans embrace electric vehicles, automakers and the federal government are racing to secure the materials needed to build EV batteries, including by pouring billions of dollars into battery recycling. Today, recyclers are focused on recovering valuable metals like nickel and cobalt from spent lithium-ion batteries. But with the trade war between the U.S. and China escalating, some are now taking a closer look at another battery mineral that today’s recycling processes treat as little more than waste.

On Dec. 1, China implemented new export controls on graphite, the carbon-based mineral that’s best known for being used in pencils but that’s also used in a more refined form in commercial EV battery anodes. The new policies, which the Chinese government announced in October shortly after the Biden administration increased restrictions on exports of advanced semiconductors to China, have alarmed U.S. lawmakers and raised concerns that battery makers outside of China will face new challenges securing the materials needed for anodes. Today, China dominates every step of the battery anode supply chain, from graphite mining and synthetic graphite production to anode manufacturing.

Along with a new federal tax credit that rewards automakers that use minerals produced in America, China’s export controls are boosting the U.S. auto industry’s interest in domestically sourced graphite. But while it could take many years to set up new graphite mines and production facilities, there is another, potentially faster option: Harvesting graphite from dead batteries. As U.S. battery recyclers build big new facilities to recover costly battery metals, some are also trying to figure out how to recycle battery-grade graphite — something that isn’t done at scale anywhere in the world today due to technical and economic barriers. These companies are being aided by the U.S. Department of Energy, which is now pouring tens of millions of dollars into graphite recycling initiatives aimed at answering basic research questions and launching demonstration plants.

If the challenges holding back commercial graphite recycling can be overcome, “the used graphite stream could be huge,” Matt Keyser, who manages the electrochemical energy storage group at the Department of Energy’s National Renewable Energy Laboratory, told Grist. In addition to boosting domestic supplies, recycling graphite would prevent critical battery resources from being wasted and could reduce the carbon emissions tied to battery production.

Graphite can be found in nature as crystalline flakes or masses, which are mined and then processed to produce the small, spherical particles needed for anode manufacturing. Graphite is also produced synthetically by heating byproducts of coal or petroleum production to temperatures greater than 2,500 degrees Celsius (about 4,500 degrees Fahrenheit) — an energy-intensive (and often emissions-intensive) process that triggers “graphitization” of the carbon atoms. 

Relatively cheap to mine or manufacture, graphite is lower in value than many of the metals inside battery cathodes, which can include lithium, nickel, cobalt, and manganese. Because of this, battery recyclers traditionally haven’t taken much interest in it. Instead, with many battery recyclers hailing from the metals refining business, they’ve focused on what they already knew how to do: extracting and purifying those cathode metals, often in their elemental form. Graphite, which can comprise up to 30 percent of an EV battery by weight, is treated as a byproduct, with recyclers either burning it for energy or separating it out to be landfilled.

“Up until recently, people talking about recycling for batteries really went after those token [metal] elements because they were high value … and because that recycling process can overlap quite a bit with conventional metal processing,” Ryan Melsert, the CEO of U.S. battery materials startup American Battery Technology Company, told Grist.

For graphite recycling to be worthwhile, recyclers need to obtain a high-performance, battery-grade product. To do so, they need methods that separate the graphite from everything else, remove any contaminants like metals and glues, and restore the material’s original geometric structure, something that’s often done by applying intense heat.

Crude recycling approaches like pyrometallurgy, a traditional process in which batteries are smelted in a furnace, won’t work for graphite. “More than likely you’re going to burn off the graphite” using pyrometallurgy, Keyser said.

Today, the battery recycling industry is moving away from pyrometallurgy and embracing hydrometallurgical approaches, in which dead batteries are shredded and dissolved in chemical solutions to extract and purify various metals. Chemical extraction approaches could be adapted for graphite purification, although there are still “logistical issues,” according to Keyser. Most hydrometallurgical recycling processes use strong acids to extract cathode metals, but those acids can damage the crystalline structure of graphite. A longer or more intensive heat treatment step may be needed to restore graphite’s shape after extraction, driving up energy usage and costs.

A third approach is direct recycling, in which battery materials are separated and repaired for reuse without any smelting or acid treatment. This gentler process aims to keep the structure of the materials intact. Direct recycling is a newer idea that’s further from commercialization than the other two methods, and there are some challenges scaling it up because it relies on separating materials very cleanly and efficiently. But recent research suggests that for cathode metals, it can have significant environmental and cost benefits. Direct recycling of graphite, Keyser said, has the potential to use “far less energy” than synthetic graphite production.

Today, companies are exploring a range of graphite recycling processes.

American Battery Technology Company has developed an approach that starts with physically separating graphite from other battery materials like cathode metals, followed by a chemical purification step. Additional mechanical and thermal treatments are then used to restore graphite’s original structure. The company is currently recycling graphite at a “very small scale” at its laboratory facilities in Reno, Nevada, Melsert said. But in the future, it plans to scale up to recycling several tons of graphite-rich material a day with the help of a three-year, nearly $10 million Department of Energy grant funded through the 2021 bipartisan infrastructure law.

Massachusetts-based battery recycling startup Ascend Elements has also developed a chemical process for graphite purification. Dubbed “hydro-to-anode,” Ascend Elements’ process “comes from some of the work we’ve done on hydro-to-cathode,” the company’s patented hydrometallurgical process for recycling cathode materials, said Roger Lin, the vice president of global marketing and government relations at the firm. Lin said that Ascend Elements is able to take graphite that’s been contaminated during an initial shredding step back to 99.9 percent purity, exceeding EV industry requirements, while also retaining the material properties needed for high performance anodes. In October, Ascend Elements and Koura Global announced plans to build the first “advanced graphite recycling facility” in the U.S.

The Department of Energy-backed startup Princeton NuEnergy, meanwhile, is exploring direct recycling of graphite. Last year, Princeton NuEnergy opened the first pilot-scale direct recycling plant in the U.S. in McKinney, Texas. There, batteries are shredded and a series of physical separation processes are used to sort out different materials, including cathode and anode materials. Cathode materials are then placed in low-temperature reactors to strip away contaminants, followed by additional steps to reconstitute their original structure. The same general approach can be used to treat anode materials, according to founder and CEO Chao Yan.

“From day one, we are thinking to get cathode and anode material both recycled,” Yan said. But until now, the company has focused on commercializing direct recycling for cathodes. The reason, Yan said, is simple: “No customer cared about anode materials in the past.”

That, however, is beginning to change. Yan said that over the past year — and especially in the last few months since China announced its new export controls — automakers and battery manufacturers have taken a greater interest in graphite recycling. Melsert also said that he’s starting to see “very significant interest” in recycled graphite.

Still, customers will have to wait a little longer before they can purchase recycled graphite for their batteries. The methods for purifying and repairing graphite still need refinement to reduce the cost of recycling, according to Brian Cunningham, the batteries R&D program manager at the Department of Energy’s Vehicle Technologies Office. Another limiting step is what Cunningham calls the “materials qualification step.” 

“We need to get recycled graphite to a level where companies can provide material samples to battery companies to evaluate the material,” Cunningham said. The process of moving from very small-scale production to levels that allow EV makers to test a product, “could take several years to complete,” he added. “Once the recycled graphite enters the evaluation process, we should start to see an uptick in companies setting up pilot- and commercial-scale equipment.“

Supply chain concerns could accelerate graphite recycling’s journey to commercialization. Over the summer, the Department of Energy added natural graphite to its list of critical materials for energy. Graphite is also on the U.S. Geological Survey’s list of critical minerals — minerals that are necessary for advanced technologies but at risk of supply disruptions.

This classification means that domestically sourced graphite can help EVs qualify for the “clean vehicle credit,” a tax credit that includes strict requirements around critical mineral sourcing following the 2022 Inflation Reduction Act. To qualify for the full credit, EV makers must obtain a large fraction of their battery minerals from the U.S. or a free-trade partner. By 2025, their vehicles may not contain any critical minerals extracted or processed by a “foreign entity of concern” — an entity connected to a shortlist of foreign countries that includes China. This requirement could “drive a premium” for domestically recycled graphite, Lin said.

Tax incentives could be key to helping recycled graphite compete with virgin graphite, according to Yuan Gu, a graphite analyst at the consulting firm Benchmark Mineral Intelligence. Despite China’s new export controls, Gu expects graphite to remain relatively cheap in the near future due to an “oversupply” of graphite on the market right now. While Gu said that graphite recycling is “definitely on radar for Western countries” interested in securing future supplies, its viability will depend on “how costly or cheap the recycled material will be.”

If graphite recycling does catch on, industry insiders are hopeful it will be able to meet a significant fraction of the country’s future graphite needs — which are growing rapidly as the clean energy transition accelerates — while making the entire EV battery supply chain more sustainable.

“You can help regional supply chains, you can help with efficiency, with carbon footprints,” Lin said. “I think it’s a no-brainer this will happen.”

Grand Prix Association of Long Beach president and CEO Jim Michaelian died on Saturday, just four weeks before the street race was scheduled to roar again along the city’s shoreline, association officials said. It was to be the last race he would oversee before passing the reins to incoming CEO Jim Liaw.

Michaelian was 83. His cause of death was not released.

Michaelian wore increasingly larger hats during the past 51 years of the annual race, serving first as the Grand Prix Association’s controller, chief operating officer and then being named president and CEO in December 2001.

“Jim didn’t just lead the Grand Prix — he lived it,” Mayor Rex Richardson said in a statement. ”His passion, warmth and dedication turned an event into a tradition, and a tradition into a source of pride for generations of Long Beach residents. Under his leadership, the Grand Prix became a global event and a defining part of Long Beach’s identity.”

Michaelian graduated from UCLA with a BS in Physics and an MBA. He was a competitive sports car racer for more than 25 years and competed in endurance events at tracks including Le Mans, Daytona, Nürburgring, Dubai and Sebring.

Penske Entertainment acquired the Grand Prix Association of Long Beach in November 2024.

Penske Corporation chairman Roger Penske reflected on Michaelian’s contributions.

“Jim was a leader of a small, passionate group who believed in the concept of bringing elite open-wheel competition to Long Beach in the 1970s, worked tirelessly to make it happen despite steep odds and then helped nurture the Grand Prix of Long Beach into becoming America’s premier street race,” Penske said. “His vision and energy surrounding this great event remained boundless for 50 years, as no task was too small for Jim, even while he served in numerous leadership roles.”

Michaelian is survived by his wife, Mary, and sons Bob and Mike.

“A loving and devoted husband, nothing meant more to Jim than his family,” the Grand Prix Association said in a statement. “He especially treasured the time he spent with his two boys, creating memories that will be carried forever.”

The Major League Baseball season kicks off this Wednesday, with the New York Yankees going up against the San Francisco Giants.

For our reigning world champs Dodgers, their home opener is on Thursday, when they play the Arizona Diamondbacks at Chavez Ravine.

This year, the Dodgers are looking to make history for the franchise with their pursuit of a back-to-back-to-back win. So, how are their chances? We take these questions to LAist's resident sports expert, Matt Dangelantonio.

How are the Dodgers looking this year?

In a word? Great. Almost the entire 2025 World Series team is returning, with a couple of major additions in the outfield and bullpen. The Dodgers are Vegas' favorites to win it all at +230, far ahead of the next team up — the New York Yankees at +1000. The Dodgers remain the team to beat in the National League West, and really in all of baseball. They are a blueprint for what can go right when you have a lot of money to spend and invest right.

The team's biggest assets?

Biggest assets are the names you already know: Ohtani, Freeman, Betts, Muncy, Teoscar, Yoshi ... the list goes on. There are also two new names folks will want to watch. One is slugging outfielder Kyle Tucker, to whom the Dodgers gave a four-year deal worth a whopping $240 million. He's a four-time All-Star who can hit 30 home runs, and is a strong defensive outfielder with a Gold Glove (2022) under his belt. One thing the Dodgers lacked last year was a de facto closer, though rookie Roki Sasaki took on that role during the postseason. Now, the Dodgers have a true closer in Edwin Diaz, a former New York Met with a proven track record of locking things down in the ninth inning — if he can stay healthy. The bullpen will also benefit from the return of past mainstays like Brusdar Graterol, Tanner Scott and Alex Vesia, who missed the World Series after the death of his newborn daughter.

The biggest concerns?

Age and health, pretty much the same as usual. Offensive woes caught up to some of the team's elder statesmen — like Freddie Freeman, Mookie Betts and Max Muncy — in the World Series, though Muncy did redeem himself with the clutch 7th-inning homer in Game 7 of the World Series to make it 3-2 and set the table for Miggy Ro's 9th-inning, game-tying homer. But those guys aren't getting any younger. Health was also an issue for the pitching staff in particular last year. Blake Snell and Tyler Glasnow both missed big chunks of time with injuries.

The archrivals?

In the NL West, it's the Padres as usual. They have a solid combination of veteran experience and youth in their lineup, a strong pitching rotation and arguably one of the best bullpens in baseball. The Mets and Phillies are likely to be the biggest potential threats to the Dodgers' reign, though both clubs have bad track records of winning when it matters. And then league-wide, the Yankees, Mariners and Blue Jays should all be very good and are each good bets to be on the opposite side should the Dodgers make it back to the World Series.

So, three-peat?

Nothing is certain in baseball, but what I'll say is ... it's their World Series to lose. I think in the eyes of owner Mark Walter and GM Andrew Friedman, anything short of a World Series win would be considered a failure, given how much money they've spent on their roster. They have absolutely no excuse not to make it back to the World Series this year if they stay healthy. They are in a unique position before the year even starts to be on cruise control through the regular season and really play their best baseball in October.

It's spring break season in the U.S. — and travelers are facing long airport lines as security screeners work without pay while the Department of Homeland security is shut down.

Congressional Democrats have declined to fund the agency in an attempt to force reforms of federal immigration enforcement practices.

Wait times at major hubs in Houston and Atlanta reached two hours on Friday, while New Orleans's Louis Armstrong International Airport advised passengers to arrive at least three hours before their scheduled departures. In Philadelphia, airport officials closed three security checkpoints entirely this week because of short staffing.

On Saturday, President Trump threatened to send Immigration and Customs Enforcement agents to staff airport security lanes if Democrats don't "immediately" agree to fund DHS. A bipartisan group of senators has been negotiating with the White House over immigration enforcement and ending the shutdown.

"I will move our brilliant and patriotic ICE Agents to the Airports where they will do Security like no one has ever seen before, including the immediate arrest of all Illegal Immigrants who have come into our Country," Trump posted on Truth Social. In a follow-up post he said he told ICE to "GET READY" to deploy to airports on Monday.

Why are wait times so long?

Officials say wait times are unpredictable and can fluctuate sharply as airports struggle with Transportation Security Administration staffing shortages.

TSA staffers are considered essential workers, so about 50,000 have been working without pay due to the shutdown that started Feb. 14. Last week, they missed their first full paychecks. The Department of Homeland Security says more than 300 TSA officers have quit. More than half of TSA staff in Houston called out sick and nearly a third called out in Atlanta and New Orleans last week, DHS said.

The staffing shortage comes as travel has also been disrupted by severe weather, and as schools across the country close for spring break.

Some 2.8 million people were projected to travel on U.S. airlines each day in March and April, adding up to a record 171 million passengers, according to the industry group Airlines for America.

What do officials say?

Transportation officials are warning the situation could get worse if the shutdown isn't resolved. A second missed paycheck would put even more strain on TSA workers, Transportation Secretary Sean Duffy told CNN on Friday.

"If a deal isn't cut, you're going to see what's happening today look like child's play," Duffy said. "Is it still safe as you go through the airport? Yes, but it takes a lot longer because we have less agents working." He added that some smaller airports may be forced to temporarily close if more staff calls out.

In the U.K., Foreign Office officials are also warning travelers of "travel disruption" caused by "longer than usual queues at some U.S. airports," and recommended passengers check with their travel provider, airport, or airline for guidance.

On Saturday, billionaire Elon Musk weighed in with an offer to personally pay TSA staff.

"I would like to offer to pay the salaries of TSA personnel during this funding impasse that is negatively affecting the lives of so many Americans at airports throughout the country," Musk posted on X early Saturday morning.

U.S. law generally bars government employees from receiving outside compensation for their work.

Even with disruptions, travel demand is still high

On top of long security wait times and weather impacts, travel is being affected by the war in Iran, which is driving up global oil prices.

On Friday, United Airlines said it would cut some flights over the next six months after jet fuel prices doubled in recent weeks. Capacity cuts are likely to send airfares even higher, even as ticket prices are already rising, said Clint Henderson, a spokesperson for the travel website The Points Guy.

Still, he said, none of that seems to be deterring Americans from flying.

"The appetite for travel is insatiable," he said. "People seem willing to endure a lot of stuff to travel. And I don't see any signs of that decreasing."

How can travelers prepare?

Travel experts say it's not just long wait times that travelers should prepare for — it's the uncertainty.

"Every day this goes on, it's getting worse and worse and worse," Henderson said.

Here are some tips on how to prepare for upcoming air travel:

1. Know before you go

Many airport websites list estimated security wait times. That should be the first place you check to get a sense of how long lines might be, Henderson says. (TSA also estimates wait times on its website and app, but that's not being regularly updated because of the shutdown, he added.)

"Knowledge is power," Henderson said. "You should know what's going on at your local airport."

He noted there are 20 U.S. airports where security screening is done by private contractors, not the TSA — and they are not experiencing staffing shortages or long waits. Some are smaller regional airports, but the list also includes some larger hubs, including San Francisco International Airport and Kansas City International Airport.

"There's big, big, big metropolitan areas where it's not an issue at all," Henderson said.

2. Budget extra time

If you're someone who shows up at the airport when your flight starts boarding, think twice, says travel writer Chris Dong.

"I'm the type of traveler who usually arrives pretty last minute," Dong said, "but I think that that advice would not be sound for the current situation."

Even if wait times are listed as short, things can change on a dime. Dong recently flew out of John F. Kennedy Airport in New York and found the TSA PreCheck line unexpectedly closed.

"So then everyone that was funneled through the regular line, it was an extra like 20, 30 minutes," he said. "I was sweating it out because I usually arrive super last-minute. And those levels of uncertainty are just higher now with the shutdown."

3. Consider biometric screening

Henderson typically recommends signing up for TSA PreCheck or the Global Entry program to move through airport security more quickly — and to opt in to biometric screening. That has to be done in advance, and travelers also have to choose biometric screening in their airline apps.

"Make sure if that's an option that you're opted in for that, because that will save you so much agita," he said.

For those who haven't signed up in advance, there is a last-minute alternative: the private CLEAR program, which allows people to enroll at the airport. Henderson notes it's pricey — annual membership costs $209 — but that some credit card companies will refund that fee.

"For me to skip a three-hour line is probably worth the membership fee, especially if you know your credit card will pay you back for it," he said.

That said, expedited screening lanes are not always faster than regular screening, both Henderson and Dong warned. Always check what all the lanes look like when you arrive at the airport.

4. Make a plan B

If you miss a connection or your flight is canceled, be proactive about rebooking. "Have all the tools available to you in the toolbox in case things go wrong," Henderson advises.

That includes installing your airline's app on your smartphone and writing down their customer service number, so you aren't scrambling to find it.

"And then, you know, obviously have a plan B," Henderson said. "Know what other airlines fly the route that you want to take in case, you know, you missed your Delta flight and American is offering a flight you can take later that day."

He says while airlines don't generally like to rebook passengers on competitors' flights, it's worth asking. He also recommends having the information at hand to give to customer service agents, including flight number, airline and departure time.

And if an airline cancels your flight in the U.S., you're entitled to a refund, according to the Department of Transportation.

Robert Mueller, the former FBI director and special counsel who led the high-profile investigation into Russian interference in the 2016 election and the possible obstruction of justice by President Trump, died on Friday at 81.

"With deep sadness, we are sharing the news that Bob passed away," his family said in a statement Saturday shared with NPR. No cause of death was given.

Mueller had been diagnosed with Parkinson's disease four years ago, his family told The New York Times in August.

Trump, who openly despised Mueller and his investigation, celebrated his death on Saturday.

"Good, I'm glad he's dead," the president posted on social media. "He can no longer hurt innocent people!"

WilmerHale, the law firm where Mueller served as a partner, remembered Mueller as a "friend" who was "an extraordinary leader and public servant and a person of the greatest integrity."

"His service to our country, including as a decorated officer in the Marine Corps, as FBI Director, and at the Department of Justice, was exemplary and inspiring," a spokesperson for WilmerHale told NPR in a statement. "We are deeply proud that he was our partner. Our thoughts are with Bob's family and loved ones during this time."

Former President Barack Obama on Saturday called Mueller "one of the finest directors in the history of the FBI, transforming the bureau after 9/11 and saving countless lives."

"But it was his relentless commitment to the rule of law and his unwavering belief in our bedrock values that made him one of the most respected public servants of our time," Obama wrote on social media. "Michelle and I send our condolences to Bob's family, and everyone who knew and admired him."

Path to public service

Born on Aug. 7, 1944 in New York City, Mueller was raised in Philadelphia and graduated from Princeton University in 1966. He received a master's degree in international relations from New York University.

Mueller, throughout his career, ran toward tough assignments. Following the lead of a classmate at Princeton, Mueller enrolled in the Marines and served in the Vietnam war. He earned the Bronze Star for rescuing a colleague. Mueller said he felt compelled to serve during that conflict, an idea he returned to throughout his life.

Law professor and former Justice Department lawyer Rory Little knew Mueller for many years.

"Bob is kind of a straight arrow, you know, wounded in Vietnam," Little said. "You keep wanting to hunt for where is the crack in that façade — 'Where is the real Bob Mueller?' — and after a while you begin to realize that's the real Bob Mueller. He is exactly who he appears to be. This kind of sour-faced, not a lot of humor, sort of all-business guy. That's him."

But with his closest friends, Mueller let down his guard. They teased him — saying Mueller would have made an excellent drill instructor on Parris Island, where Marine recruits are trained.

Instead, Mueller went to law school at the University of Virginia. He joined the Justice Department in 1976. There, he prosecuted crimes, big and small, for U.S. attorneys in San Francisco and Boston. He was a partner at Hale and Dorr, a Boston law firm now known as WilmerHale.

He later became a senior litigator prosecuting homicides at the U.S. attorney's office in Washington, D.C.

Head of the FBI

In 2001, President George W. Bush nominated him to serve as the director of the FBI. Mueller was sworn in a week before the Sept. 11 terrorist attacks.

"I had been a prosecutor before, so I anticipated spending time on public corruption cases and narcotics cases and bank robberies, and the like. And Sept. 11th changed all of that," Mueller told NPR during an interview in 2013.

He shifted the bureau's attention to fighting terrorism. He staffed up the headquarters in Washington. He pushed those agents to try to predict crimes and to act before another tragedy hit.

"He directed and implemented what is arguably the most significant changes in the FBI's 105-year history," said his former FBI deputy, John Pistole.

Along the way, Mueller drew some criticism when his agents erred. During the investigation of the deadly anthrax attacks, the bureau focused on the wrong man as its lead suspect.

Mueller left the bureau in 2013.

Return to the national spotlight

After Trump fired FBI Director James Comey, Mueller in May 2017 was appointed by then Deputy Attorney General Rod Rosenstein as special counsel to oversee the probe into Russian meddling in the 2016 election and possible connections to Trump associates.

Trump called the investigation "a witch hunt" and Republicans in Congress started to attack the investigators.

When then the investigation eventually concluded in March 2019 with the more than 400-page "Mueller report," the special counsel said the investigation did not establish that Trump's campaign or associates colluded with the Russian government to influence the 2016 election. The report did not take a position on whether Trump obstructed justice.

Mueller said the report spoke for itself. But Democrats wanted more and insisted he testify. A reluctant witness, Mueller once again fulfilled his duty. He was visibly older than at the time of his appointment and kept his testimony restrained.

He said Justice Department guidelines would not allow him to charge a sitting president with criminal wrongdoing. But he also refused to exonerate Trump.

"If we had had confidence that the president clearly did not commit a crime, we would have said so," Mueller later told Congress.

In the end, the team charged 37 people and entities, including former campaign chair Paul Manafort, national security adviser Michael Flynn and 25 Russians.

Trump went on to grant clemency to or back away from criminal cases against many of the people Mueller's investigators had charged.
