GM, LG to invest $2.3bn to build second EV battery plant in US

General Motors is already at work on the next evolution of its Ultium battery cells. GM R&D Lab Group Manager Mei Cai, PhD, displays a working prototype of a battery cell with a lithium metal anode, a significant step on the path to remarkable energy density breakthroughs, with even more power and range at lower costs. This cell has already completed more than 500 deep charge/discharge cycles. (Photo by Steve Fecht for General Motors)
