QuantumScape Corporation, a developer of next-generation solid-state lithium-metal batteries for use in electric vehicles, released an independent third-party laboratory testing report on the performance of its solid-state lithium-metal battery cells. QuantumScape’s single-layer cells were tested by Mobile Power Solutions , an independent battery lab, and met automotive-relevant conditions: more than 800 cycles at 25 °C, 1C (one hour) charge/discharge rates, 100% depth of discharge and under 3.4 atmospheres of pressure. The company said that it believes that the results from the tests, covering a group of three single-layer cells, are consistent with those initially reported by QuantumScape in December 2020. ( Earlier post .) We are happy that these independent test results substantially replicate the cycling performance we reported at our December 2020 Battery Showcase. With the publication of this report, we will continue to focus on our product roadmap goals and delivering cells to our customers. —Jagdeep Singh, […]
