NCM Battery Cell
Nickel Cobalt Manganese Oxide battery cell
This battery delivers a high energy density, with gravimetric energy density reaching up to 220 Wh/kg, 260 Wh/kg, or even 300 Wh/kg. It also offers strong rate capability, supporting continuous discharge rates of 5C–15C along with even higher pulse discharge performance. The battery excels in low-temperature operation, retaining approximately 80% of its capacity at –30°C. Furthermore, it provides a relatively long cycle life, capable of over 1,500 cycles under 5C charge and 7C discharge conditions while maintaining more than 80% capacity retention.
