- kenhwang 7y agoThe biggest advantages of NMC over NCA are: - NMC can charge and discharge faster - NMC has longer cycle life - NMC is more heat tolerant Advantages of NCA over NMC are: - NCA is cheaper due to less cobalt use and no magnesium with slower growing demand than NMC which further helps cost going forward - NCA has better energy density (capacity/weight) By far the biggest disadvantage of NCA is it's thermal profile. It's more difficult to cool due to the higher energy density, and prone to fire or explosion when overcharged, overheated, or subjected to physical damage. NCA is a much older battery chemistry than NMC. Historically it's applications have been limited to handheld tools because of how dangerous a mistreated large NCA battery could be.
