QuantumScape Data Shows Industry-First 15-minute Fast Charging for Hundreds of Consecutive Cycles
QuantumScape Corporation (NYSE:QS), a leader in the development of solid-state lithium-metal batteries, today released data showing its battery cells have completed 400 consecutive 15-minute fast-charging (4C) cycles from 10% to 80% of the cell's capacity while retaining well above 80% of the initial energy – a first for this type of battery technology. QuantumScape conducted the tests on commercially relevant sized single-layer prototype battery cells at multiple temperatures (25 °C and 45 °C), 3.4 atmospheres of pressure and 100% depth of discharge.
Internal combustion engine vehicles can be refueled in about 5 minutes, whereas today's leading lithium-ion electric vehicle (EV) batteries
