Since 2012, Volkswagen Group Research has already been collaborating closely with the Stanford spin-off. Based on the significant technical progress that this cooperation has made, QuantumScape and Volkswagen will work together within a newly formed joint venture with the aim to enable an industrial level of production of solid-state batteries. One of the long-term targets is to establish a production line for solid-state batteries by 2025.
Founded in 2010, QuantumScape is headquartered in San José, California and holds approximately 200 patents and patent applications for solid-state battery technology. Its deep expertise makes the company a leading pioneer in the development of this form of energy storage. “The solid-state battery will mark a turning point for e-mobility”, says Axel Heinrich of Volkswagen Group.
Solid-state battery cell technology is seen as the most promising approach for the e-mobility of the future. For example, a solid-state battery would increase the range of the E-Golf to approximately 750 kilometers compared with the present 300 kilometers. This battery technology has further advantages over the present lithium-ion technology: higher energy density, enhanced safety, better fast charging capability and – above all – they take up significantly less space. A solid-state battery of the same size as a current battery package can achieve a range comparable to that of conventional vehicles.
While the approach has a lot of promise, advances have been difficult to attain and no other battery supplier has been able to achieve automotive performance. Volkswagen successfully tested QuantumScape early-stage solid-state battery sample cells in Germany running at automotive rates of power—an industry first.
