The Volkswagen Group has announced it is increasing its stake in solid state battery maker QuantumScape. According to VW, the goal of the further investment of up to $200 million is to boost the development of solid state battery technology. Solid state batteries promise to enable ranges for EVs that are comparable with traditional drivetrains, while significantly reducing charging time. “Volkswagen is taking e-mobility to the mainstream. A strong position in batteries is a decisive factor in this regard”, said Frank Blome, head of the Battery Cell business, Volkswagen Group Components. VW and QuantumScape have been collaborating on the joint venture for nearly two years. Solid–state batteries are said to pack more power per pound, last longer and are safer, given they dispense with the more volatile liquid or polymer gel use in traditional lithium ion batteries.
