Colorado startup Solid Power claims to have made a breakthrough in solid state lithium ion battery technology. Unlike a conventional lithium ion battery, which uses a "volatile, flammable, and corrosive liquid electrolyte," solid state batteries use a solid electrolyte. Solid Power claims their batteries will have a "2-3X higher" energy capacity than conventional lithium ion technology, while being safer and cheaper due to manufacturing simplifications and less of a need for expensive safety and cooling equipment. The startup already has funding from major industry players like BWM, Hyundai and Samsung, and claims their factory will be fully operational in 2019. "We are at the center of the 'electrification of everything' with ASSB technology emerging as the clear leader in 'post lithium-ion' technologies. Solid-state batteries are a game changer for EV, electronics, defense, and medical device markets, and Solid Power's technology is poised to revolutionize the industry with a competitive product paying special attention to safety, performance, and cost."
