GM, LG to make new, low-cost batteries for future e-vehicles
General Motors and battery partner LG Energy Solution are planning to start commercial production of lower-cost cells for future electric vehicles at a US facility starting in 2028, the companies said on Tuesday.
The cells will have a lithium manganese-rich (LMR) chemistry, which GM says is lower cost than the nickel-rich cells used today, but will still give customers the range they want in future electric trucks and full-size SUVs. The cells will also be prismatic versus the current pouch structure, reducing the number of parts in the battery pack by more than 50per cent, according to GM.
The Detroit automaker, which now has 12 electric vehicles in its lineup, is trying to lower its battery costs to enable cost parity with its gas-powered products by adding new types of cells and chemistries in those cells. "We're adopting flexible chemistries for the best balance of range, performance and affordability," said Kurt Kelty, GM's vice president of battery, propulsion and sustainability during a media briefing on the announcement. "My mission here is to get as many EVs on the road as possible. We need to get price parity with (internal combustion engine vehicles) and then this thing's just going to take off."
The LMR cells will be made at one of the two LG-GM joint-venture Ultium Cells battery plants the companies have in Ohio and Tennessee. With the LMR prismatic cells, GM expects to offer more than 400 miles of range in a single charge on an electric truck, "while significantly reducing our battery costs," Kelty said.
GM is expecting to reduce its battery pack costs by $30 per kilowatt-hour in 2025, but it hasn't said how much its per-kilowatt-hour costs are. GM is also planning to offer vehicles with lithium-iron phosphate-based cells that are also lower cost than the nickel cells. Kelty said GM will release more information soon.

China okays rare earth licences to suppliers of top three US auto companies
China has granted temporary export licenses to rare-earth suppliers of the top three US automakers, two sources familiar with the matter said, as supply chain disruptions begin to surface from Beijing's export curbs on those materials. At least some of the licenses are valid for six months, the two sources said, declining to be named because the information is not public. It was not immediately clear what quantity or items are covered by the approval or whether the move signals China is preparing to ease the rare-earths licensing process, which industry groups say is cumbersome and has created a supply bottleneck. China's decision in April to restrict exports of a wide range of rare earths and related magnets has tripped up the supply chains central to automakers, aerospace manufacturers, semiconductor companies and military contractors around the world. China's dominance of the critical mineral industry, key to the green energy transition, is increasingly viewed as a key point of leverage for Beijing in its trade war with US President Donald Trump . China produces around 90% of the world's rare earths, and auto industry representatives have warned of increasing threats to production due to their dependency on it for those parts. Suppliers of three big US automakers, General Motors , Ford and Jeep-maker Stellantis got clearance for some rare earth export licenses on Monday, one of the two sources said. GM and Ford each declined to comment. Stellantis said it is working with suppliers "to ensure an efficient licensing process" and that so far the company has been able to "address immediate production concerns without major disruptions." China's Ministry of Commerce did not immediately respond to a faxed request for comment. China's critical-mineral export controls have become a focus on Trump's criticism of Beijing, which he says has violated the truce reached last month to roll back tariffs and trade restrictions. On Thursday, Trump and Chinese President Xi Jinping had a lengthy phone call to iron out trade differences. Trump said in social-media post that "there should no longer be any questions respecting the complexity of Rare Earth products." Both sides said teams will meet again soon. US auto companies are already feeling the impact of the restrictions. Ford shut down production of its Explorer SUV at its Chicago plant for a week in May because of a rare-earth shortage, the company said.

China issues rare six-month valid earth licenses to suppliers of top US automakers amid global trade tensions

"We have to give the Chinese the benefit of the doubt that they're working through this. It's up to them to show that they are not weaponizing it," said the person. Reuters reported on Wednesday that China has introduced a tracking system for its rare earth magnet sector in a move to improve its control over the sector and crackdown on smuggling.

US Senate Republicans propose eliminating fuel economy fines for automakers
U.S. Senate Republicans on Thursday proposed eliminating fines for failures to meet Corporate Average Fuel Economy rules as part of a wide-ranging tax bill - the latest move aimed at making it easier for automakers to build gas-powered vehicles . Last year, Chrysler-parent Stellantis paid $190.7 million in civil penalties for failing to meet U.S. fuel economy requirements for 2019 and 2020 after paying nearly $400 million for penalties from 2016 through 2019. GM previously paid $128.2 million in penalties for 2016 and 2017. Thursday's proposal also makes emissions credits sold by Tesla less valuable as rivals won't have to pay Tesla to meet requirements. The lawmakers estimated it would save automakers $200 million. GM and Chrysler did not immediately comment. U.S. House Republicans are pursuing similar aims but with a different approach. Last month they proposed repealing planned hikes in fuel economy requirements as well as vehicle emissions rules adopted under the Biden administration . The House bill would also kill a $7,500 tax credit for new electric vehicles , impose a new $250 annual fee on EVs for road repair costs and would phase out EV battery production tax credits in 2028. The two chambers have also voted to bar California's landmark plan to end the sale of gasoline-only vehicles by 2035 which has been adopted by 11 other states representing a third of the U.S. auto market. That bill is currently awaiting U.S. President Donald Trump's signature. The Transportation Department is expected to declare that fuel economy rules issued under Biden exceeded the government's legal authority by including EVs. Last year, the National Highway Traffic Safety Administration said it would hike fuel economy rules to an average of 50.4 miles per gallon (4.67 liters per 100 km) by 2031 - up from 39.1 mpg for light-duty vehicles. It warned the auto industry collectively was expected to face a total of $1.83 billion in fines through 2031.
