Tesla models all use ternary lithium batteries, and the positive electrode of this battery is made of ternary materials. Ternary materials refer to three materials, namely nickel, cobalt and manganese. Some ternary lithium batteries also use nickel, cobalt and aluminum to make positive electrodes. Battery brands used in Tesla batteries include Panasonic and CATL. Tesla's first generation "18650" battery was supplied by "Panasonic" and was used until the launch of Model S and Model X. The second generation "2170" power battery is also supplied by "Panasonic" and was used in the Model 3 and Model Y. Tesla electric cars use 18650 batteries produced by Panasonic. The batteries used by Tesla look like regular AA batteries, but they are actually 18650 lithium batteries.Different models use different types of batteries. Tesla uses 18650 batteries produced by Panasonic. Once Model 3 is officially put into production, the new 21700 batteries will replace the 18650 and become the new battery core. The 21700 battery is a ternary lithium battery, and the cathode material is lithium-nickel-cobalt aluminate (NCA). This cylindrical ternary battery is currently the highest energy density power battery solution.
Tesla electric vehicles mainly use ternary lithium batteries.
Early Tesla models, such as the Roadster, used Panasonic's 18650 ternary lithium battery, while later models, such as the Model 3, began using the battery ternary lithium 21700, more advanced. The cathode material of ternary lithium battery is mainlycomposed of three elements: nickel, cobalt and manganese (or aluminum). It has the advantages of light weight, large capacity and high energy density, and is very suitable for pure use). electric vehicles. Tesla's Battery Management System (BMS) is also very capable, ensuring the stability and safety of the battery during operation.
