Advancements in battery innovation are transforming both mobility and energy systems alike, according to Kurt Kelty, vice president of battery, propulsion, and sustainability at General Motors (GM). At the MIT Energy Initiative (MITEI) Fall Colloquium, Kelty explored how GM is bringing next-generation battery technologies from lab to commercialization, driving American battery innovation forward. The colloquium is part of the ongoing MITEI Presents: Advancing the Energy Transition speaker series.

'It's the batteries. The batteries make up about 30 percent of the cost of the vehicle.' Second, his team strives to improve battery performance, including charging speed and energy density. Third, they are working on localizing the supply chain. 'We've got to build up our resilience and our...
