The solid-state battery cell technology is regarded as the most promising approach to electromobility of the future. With a solid fuel battery, for example, the range of an e-Golf would increase from the currently 231 (WLTP) to approximately 750 kilometers. Compared to current batteries, this battery technology offers higher energy density, greater safety, better rapid charging capability and lower space requirements. With the same size of a current battery pack, the solid battery enables electrical ranges at the level of conventional drives. In 2019, Volkswagen established a joint venture with QuantumScape Corporation — a start-up of Stanford University – to advance the research, production and marketing of solid-state batteries.
