The QuantumScape battery charges at blazing speeds, allowing a 0-80% charge in 15 minutes. It can retain more than 80% of its capacity after 800 cycles, which would represent about 240,000 miles (386,000 km) traveled in an electric car.
This is the quote. If it's one hour charge, i.e. 1C, lifepo4 batteries do that already.
