General Motors expects to pioneer a new “groundbreaking” EV battery technology that the automaker says will reduce costs and boost profitability of its largest electric SUVs and trucks.

The automaker is working with LG on 'lithium manganese-rich' batteries, which could bring up to 33% more energy with no price increase on big trucks and full-sized SUVs.

General Motors has cracked the chemistry of lower-cost, energy-dense electric vehicle batteries. Budget-conscious gasoline holdouts may soon have no excuse.
