Volkswagen partners with QuantumScape on solid-state batteries

Volkswagen Group paving the way for the next level of battery power for long-range e-mobility has increased its stake in QuantumScape Corporation and has formed a new joint venture with the company. Both the companies have been collaborating since 2012.

Founded in 2010, QuantumScape is headquartered in San José, California and holds approximately 200 patents and patent applications for solid-state battery technology. It has got  deep expertise in the development of this form of energy storage.

The joint venture aims to enable an industrial level of production of solid-state batteries and one of the long-term targets is to establish a production line for solid-state batteries by 2025.

Solid-state battery cell technology is seen as the most promising approach for the e-mobility of the future. They have advantages over the present lithium-ion technology: higher energy density, enhanced safety, better fast charging capability and 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. These batteries have potential to increase the range of the E-Golf to approximately 750 kilometers compared with the present 300 kilometers.

While the approach has a lot of promise, advances have been difficult to attain and the company claims that 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.
