both are mainly applied in e-bike, electrical power tool with high drain power supplier, but each battery has each advantages and disadvantages.
advantages and disadvantages of LiNiCoMnO2 compared with LiFePO4
That means to reach a higher voltage, lifepo4 battery will use more cells in seriese connection. so battery cells increased and size increased as well. therefore, cost increased accordingly.
That means in unit space, NCM could get more electric power than lifepo4.
for example, 48v 24ah battery pack, lifepo4 will use 16s5p 80pcs cells, while NCM only need 13s5p 65pcs cells. size and weight deducted thereto, price down also, these are good for e-bikes.
2). NCM can discharge when temperature below 0℃
when temperature drops to 0℃, lifepo4 can not discharge anymore. it's dull, not active. you can say safe, but not applicable in real application.
while, NCM can still discharge at -10~-20℃, depend on material composition recipe. more active, doest not mean it's unsafe. because recipe with electrolyte matching and control, it's safe under control, and it's released forbidden to use in new energy electric car, bus and even sport car etc.
3). cycle life comparison
