24M emerges from stealth mode with new semi-solid Li-ion cell; <$100/kWh by 2020

Green Car Congress

Co-founded by MIT’s Dr. Yet-Ming Chiang, 24M’s Chief Scientist, the company is leveraging existing, preferred energy storage chemistry but using a new cell design with semi-solid (a mixture of solid and liquid phases) thick electrodes and manufacturing innovations to deliver what it says will be up to a 50% reduction in current Li-ion costs.
