EV batteries

General Motors (GM) has announced a strategic investment and commercial collaboration with Controlled Thermal Resources (CTR) to secure lower-cost lithium in the US for the development of its next generation of EV batteries. The legacy automaker hopes this collaboration will garner more environmentally friendly methods of obtaining precious lithium while simultaneously help lower the price of its EVs.

Studies have shown that EV range can drop by as much as 40% when temperatures drop below 20°F and the heater is running. Tesla and others might dispute the exact amount of lost range, but there’s broad agreement that cold weather has a meaningful impact. That challenge led the US Department of Energy’s Office of Energy Efficiency and Renewable Energy to award $480,000 to Professor Brett Lucht to study how to improve battery performance in low temperatures.

While California represents the majority of EV sales in the US, the American South is the auto manufacturing powerhouse of the country. Yet, southern states have been among the slowest to adopt electric vehicles. That needs to change, argues Gerald Allen, a Republican member of the Alabama State Senate.

The Lexus UX 300e, the luxury brand’s first EV, is on sale in China now and hits Europe later this year. Lexus in Europe announced today that the crossover’s air-cooled 54.3-kilowatt-hour battery will come with a 10-year, 1 million-kilometer (621,000-mile) warranty. The Lexus UX300e joins the Nissan Leaf as one of the few EVs with air-cooled batteries, which are considered not as robust.

Two research institutes at the University of California, Berkeley, today released a research brief about the global supply of batteries for electric vehicles. Many millions of batteries will be needed for EVs in the coming decades. Here’s the overarching question: How can the supply of those batteries meet that demand in a sustainable way?
