What type of batteries do Tesla cars use?

[Jayce]

Tesla's vehicle models all use ternary lithium-ion batteries, specifically the 18650 batteries produced by Sony. These batteries are similar in size to AA batteries, and a Tesla car contains approximately 8,000 of these 18650 batteries. Ternary Lithium-ion Batteries: 1. The cathode is made of ternary materials. Ternary materials refer to three types of materials: nickel, cobalt, and manganese. Some ternary lithium-ion batteries may also use nickel, cobalt, and aluminum to make the cathode. 2. Ternary lithium-ion batteries are currently quite popular, with most pure electric vehicles using them. Lithium-ion batteries are lighter in weight and have higher energy density, making them very suitable for pure electric vehicles. Some pure electric vehicles also use lithium iron phosphate (LFP) batteries, which offer better safety compared to ternary lithium-ion batteries. However, LFP batteries have lower energy density and are heavier than ternary lithium-ion batteries.
