Charge Rates for Next-Generation Batteries | QuantumScape
A C-rate higher than 1C means a faster charge; for example, a 3C rate is three times faster, so a full charge in 20 minutes. Likewise, a lower C-rate means a slower charge: C/5 (or 0.2C) would be five

Battery C Rating Chart
A battery with a 1C rating can be charged at a current equal to its capacity. For example, a 1000mAh battery can charge at 1000mA (1A). Charging at higher C-rates can reduce charge time.
