One year after initial deliveries of solid-state battery prototypes to its automotive partners, QuantumScape is receiving additional praise from PowerCo – the battery-centric subsidiary of Volkswagen Group – for the potential of its technology. PowerCo recently completed an endurance test with QuantumScape’s solid-state cells and determined they can someday power EVs that can drive 500,000 kilometers with virtually no loss of range.

QuantumScape ($QS) is an advanced battery technology company that has been working for over a decade to develop scalable, energy-dense solid-state battery cells that can one-day power EVs that are safer, charge faster, and drive farther.

During QuantumScape’s tenure in solid-state battery development, Volkswagen Group has been a partner from early on and remains one of the startup’s largest investors. OEMs like Volkswagen have helped empower QuantumScape to continue its development and deliver some of the most promising solid-state battery technology in the industry.

In December 2022, the company delivered its first batch of 24-layer solid-state cells to its automotive partners for testing – including Volkswagen Group and others. We’ve since seen QuantumScape develop even more energy-dense cells and, as of October 2023, exceeded performance targets during testing.

Recently, Volkswagen Group’s battery subsidiary PowerCo completed its own endurance tests with QuantumScape’s 24-layer cells and is reporting encouraging results for future EVs that will offer better range with significantly less battery degradation.

VW Group pleased with QuantumScape’s SSB range

According to a report from PowerCo, it has officially confirmed performance metrics previously shared by QuantumScape, bringing longer-range EVs even closer to scaled implementation. The battery company under the VW Group umbrella detailed its endurance testing process, which took place over several months at its laboratory in Salzgitter, Germany, and put the solid-state cells through over 1,000 charge cycles.
