Supposedly Tesla uses NCA for its cars and NMC for Powerwalls. Most other electric car manufacturers use NMC. However the properties of a battery vary greatly depending on the structure of the cell, and even more so on the cooling of the battery, so you should not compare them on chemistry alone. The reason why LiFePo4 (LFP) is safer is because it doesn't exhibit thermal runaway and is less energy dense. https://www.powertechsystems.eu/home/tech-corner/safety-of-lithium-ion-batteries/ https://www.powertechsystems.eu/home/tech-corner/safety-of-l...
