Tesla Battery Types and Chemistries

Tesla offers different battery types and chemistries for their vehicles, including NCA (Nickel-Cobalt-Aluminum), NCM (Nickel-Cobalt-Manganese), LFP (Lithium Iron Phosphate), and the upcoming 4680 Battery Pack.

NCA (Nickel-Cobalt-Aluminum)

Tesla uses NCA, or Nickel-Cobalt-Aluminum, for its batteries. This type started with the Model S in 2011. They are strong and work well because of the aluminum in them. Now Tesla uses these batteries for some cars but not all.

For standard-range cars, they use a different kind called lithium-iron-phosphate (LFP). But NCA still shows up in other models. It’s one part of how Tesla makes great electric cars.

NCM (Nickel-Cobalt-Manganese)

NCM stands for Nickel-Cobalt-Manganese. These are the parts that make up this type of Tesla battery. The recipe is easy to remember: it’s one-third nickel, one-third manganese and one-third cobalt.

The use of NCM batteries is not rare in Tesla cars. In fact, a big part of the electric car battery market uses nickel-based chemistries like NCM batteries. On its own, this kind took up 75% of all used cathode materials last year! But keep in mind that nickel and cobalt can be hard to get since they’re very sensitive due to political and economic factors.

LFP (Lithium Iron Phosphate)

Tesla is moving to use LFP batteries in its standard-range cars. These batteries are free of cobalt. That makes them kind to the earth. They also have a longer life and keep you safe better than other types.

Despite less energy density, they stand up well against high heat. It’s no wonder why almost half of Tesla’s new cars now use these green and long-lasting batteries.

4680 Battery Pack

The 4680 battery pack is one of the four types of batteries used in Tesla’s electric vehicles. It is a cylindrical lithium-ion battery that has a diameter of 46mm and a height of 80mm.

The cathode, which is an important part of the battery, is made up of NCM 811, which contains about 81.6% nickel. There have been two generations of the 4680 battery, with the second generation having a higher energy density of around 305 Wh/kg.

Tesla announced this battery at their Battery Day event in September 2020.
