GM to build electric Silverado pickup at Factory Zero in Detroit
Chevrolet’s upcoming Silverado electric pickup truck will be built at the company’s Factory Zero assembly plant (the former Detroit-Hamtramck Assembly Center, now retooled for the exclusive production of battery-electric vehicles). GM plans to deliver more than 1 million electric vehicles globally by 2025. Thanks to its new Ultium Platform, along with modern virtual development tools… Read more »
GM and LG may build a second battery factory in Tennessee
If GM is going to electrify most of its lineup by 2035, it’s going to need a lot more batteries. Sending out press releases is fast and free, but building supply chains takes years and billions, so one indication of whether the automaker’s announced deadline is a serious objective or a mere aspiration will be… Read more »
2024 Chevy Equinox EV: Is this the electric SUV for average Americans?
It took far too long to get here, but it may have been worth the wait. The 2024 Chevrolet Equinox EV, GM’s smallest and least expensive battery-electric vehicle, is finally rolling into dealerships across the country. Now we’ve driven it, and it’s good. You can view the electric Equinox as the anti-Tesla. Where the Silicon… Read more »
GM hires EV superstar Kurt Kelty as Vice President of Batteries
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 »
