QS Battery Safety Report

Safety is one of the most critical performance capabilities of any battery – and we believe QuantumScape’s solid-state lithium-metal battery technology has the potential to simultaneously offer an improved safety profile as well as enable better energy, power, fast-charging, and cycle life than existing high-energy EV batteries.

In this video, QuantumScape Senior Director of Cell Design & Manufacturing Daniel Braithwaite and Senior Manager of Battery Safety Giovanni Flores share safety testing results from 24-layer prototype cells based on our Alpha-2 cell design.
