  • Requirements exceeded: Solid-state battery from QuantumScape achieved more than 1,000 charging cycles with still more than 95 percent capacity. Depending on the model, an electric car could drive more than 500,000 kilometers without any noticeable loss of range.
  • Performance confirmed: The battery tests were carried out in the laboratories of PowerCo SE, the battery company of the Volkswagen Group.
  • PowerCo CEO Frank Blome: "These are very encouraging test results and a milestone on the way to series production of the solid-state cell."

Wolfsburg. The solid-state cell is considered a technology of the future and the next big step in battery development. The technology promises longer ranges, shorter charging times and maximum safety. The U.S. company QuantumScape has recently reached an important milestone, which was now confirmed by PowerCo: its solid-state cell has significantly exceeded the requirements in the A-sample test and successfully completed more than 1,000 charging cycles. For an electric car with a WLTP range of 500-600 kilometres, this corresponds to a total mileage of more than half a million kilometres. At the same time, the cell barely aged and still had 95 percent of its capacity (or discharge energy retention) at the end of the test. The tests, which ran for several months, were carried out in PowerCo's battery laboratories in Salzgitter

The specified fuel consumption and emission data does not refer to a single vehicle and is not part of the offer but is only intended for comparison between different types of vehicles. Additional equipment and accessories (additional components, tyre formats, etc.) can alter relevant vehicle parameters such as weight, rolling resistance and aerodynamics, affecting the vehicle's fuel consumption, power consumption, CO2 emissions and driving performance values in addition to weather and traffic conditions and individual driving behavior. Further information on official fuel consumption data and official specific CO2 emissions for new passenger cars can be found in the "Guide to fuel economy, CO2 emissions and power consumption for new passenger car models", which is available free of charge from all sales dealerships and from DAT Deutsche Automobil Treuhand GmbH, Hellmuth-Hirth-Str. 1, D-73760 Ostfildern, Germany and at www.dat.de/co2.
