Which company supplies the batteries for Tesla cars?

[LolaAnn]

Tesla's battery suppliers are primarily two companies: LG and Panasonic. As of now, Tesla cars use 18650 lithium-ion batteries. Tesla chose Panasonic's 18650 batteries for the following four main reasons: 1. Higher energy density with better stability and consistency; 2. Effectively reduces the cost of the battery system; 3. Billions of 18650 batteries are produced globally each year, with continuously improving safety standards; 4. Small size but high controllability, minimizing the impact of potential failures. Battery requirements: stable performance, high safety coefficient, and multiple recharge cycles.
