It’s plain to anyone who follows the auto industry that there are pro-EV and anti-EV factions at every legacy automaker. For the last three decades, the OEMs’ interest in EVs has flapped this way and that in the winds of quarterly earnings and political shifts. Last fall, the “let’s wait awhile” contingent appeared to have… Read more »

Thermal runaway in EV battery packs: designing a mitigation strategy
Aspen Aerogels’ cutting-edge materials protect against thermal runaway Thermal runaway occurs inside a battery cell through a fault, a crash scenario or some other defect that causes the cell to release thermal energy through chemical reactions. That thermal energy increases the temperature of the cell, the increased temperature drives faster kinetics, and more heat is… Read more »
GM and Lithium Americas to develop lithium production through $650-million investment
General Motors and Lithium Americas plan to jointly invest in the development of the Thacker Pass mine in Nevada, which the companies call “the largest known source of lithium in the US.” GM plans to use lithium carbonate from Thacker Pass in its proprietary Ultium battery cells. As part of the deal, GM will make… Read more »
GM and Microvast to develop new battery separator tech, build US plant
GM and battery manufacturer Microvast are collaborating to develop specialized EV battery separator technology, and to build a new separator plant in the US, supported by a $200-million grant from the DOE’s Battery Materials Processing and Battery Manufacturing initiative. Separators are battery components that separate the anode from the cathode, while allowing for ion transfer…. Read more »
Don’t just delay cell-to-cell thermal propagation, stop it.
Sponsored by Aspen Aerogels Battery engineers face the daunting challenge of maximizing thermal runaway protection while optimizing vehicle performance. This task becomes even more critical as cell-to-pack and cell-to-chassis designs increase in popularity because manufacturers lose the added protection that can be built into a module-based design. Although newer chemistries such as LFP and solid-state… Read more »
Cadillac’s ambitious move to an all-electric luxury brand by 2030
The car that once advertised itself as “The Standard of the World” will go all-electric. Can the US luxury brand reinvent itself for a modern era…and for China? Among cutting-edge automotive buyers—the glitterati of Los Angeles, the tech millionaires of Silicon Valley, the finance titans of Wall Street—only one Cadillac is widely recognized. It’s a… Read more »
2024 Chevrolet Blazer EV: Chevy previews a mass-market electric SUV
Mid-size five-seat crossovers are a huge segment, and Chevy wants yours to plug in—next year. Chevrolet, it seems, doesn’t want to scare potential shoppers by offering up electric vehicles that stress too heavily the fact they’re … well, different. An advance preview of the upcoming 2024 Chevrolet Blazer EV suggested it’s very much a Chevy… Read more »
LG Energy Solution to invest $1.7 billion to expand its plant in Holland, Michigan
LG Energy Solution plans to invest $1.7 billion at its battery component plant in Holland, Michigan, an expansion that’s expected to quintuple the plant’s capacity. The facility manufactures large lithium-ion polymer battery cells and packs for EVs. The company is one of the largest employers in the community, and now has 1,495 employees in Michigan….

GM’s “fuel cell power cubes” could replace diesel and gas generators
Automakers have invested big bucks in fuel cells over the past few years, and they’d probably be glad to find some viable applications for the technology. GM is developing ways to apply its Hydrotec fuel cell technology to power generation. GM is planning multiple Hydrotec-based power generators, all powered by GM’s Generation 2 Hydrotec fuel… Read more »
2024 Chevrolet Silverado EV faces off against 2022 Ford F-150 Lightning
Two electric pickups from GM and Ford makers take surprisingly different approaches to electrifying the full-size truck The 2024 Chevrolet Silverado EV unveiled today by General Motors CEO Mary Barra shows the largest US auto company’s determination to hang onto its core large-pickup market even as vehicles of all sorts accelerate the transition from gasoline… Read more »
