Quantumscape achieves solid-state batteries that can fast charge in 15 minutes through 400 consecutive cycles.
A few days ago Quantumscape, which is one of the leaders in developing solid-state batteries for electric cars 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 typically need around 30 minutes to fast charge from 10% to 80% capacity at a rate that doesn’t reduce the battery’s lifetime. This longer charge time prevents EVs from providing the same user experience as internal combustion engine vehicles. If QuantumScape can successfully deliver today’s demonstrated capability into the marketplace, the time difference between recharging EVs and refueling their combustion-engine counterparts will be only several minutes, which could help enable broader EV adoption," says the company in its release.
