While breakthroughs could be a decade away, the lithium metal battery could offer a major leap in capability for electric vehicles and the grid.
While lithium-ion batteries are undergoing an historic scale-up, researchers are also hard at work looking for what battery technology might come next.
MIT professor Yet-Ming Chiang has launched his latest storage bet, a flow battery startup designed to make renewable energy directly competitive with fossil fuels (see “24M’s Batteries Could Better Harness Wind and Solar Power”).
