GM says it has developed cells that will make batteries cheaper and more energy dense. The automaker aims to be the first to bring them to market.

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.
