(A factoid: Though the battery is called lithium-ion, lithium is only 2% of the battery, which consists mostly of nickel and other metals. Rodney Dangerfield would say that nickel gets no respect, and he’d be right.)
One of the biggest differences between the Tesla battery and the batteries used in other companies’ EVs (like the BMW i3, Chevy Volt, and Jaguar i-PACE) is the metals they put in the cathode. Traditional car companies chose the NMC (nickel, manganese, cobalt) combination, while Tesla ended up making a less conservative choice of NCA (nickel, cobalt, aluminum). NCA offers long battery life, quick charging, and great performance. NMC, on the other hand, produces slightly less energy but is less volatile and withstands larger ranges and variations of temperature.
