Kurt Kelty, vice president of battery, propulsion and sustainability at General Motors, discusses a flurry of recent battery developments that underscore the automaker’s long-term electric vehicle outlook.

They include a new foray into energy storage systems alongside Redwood Materials, for which GM will provide both new and second-life batteries, production plans for lithium iron phosphate batteries with Ultium Cells in Spring Hill, Tenn., and work on a lithium manganese-rich chemistry. 

Kelty, a Tesla veteran, also talks about his time building Tesla’s Gigafactory with JB Straubel and Elon Musk, and why it was so important that the upstart make its own battery cells.
