Tesla
Tesla reshaped the industry, and it now makes its own 4680 cells alongside those from Panasonic, LG and CATL, powering its cars and its Megapack and Powerwall storage lines.
Profile
Tesla is the American electric-vehicle and energy company whose demand did more than any other to scale the modern lithium-ion battery industry. Its vehicles and its energy-storage products (Powerwall and Megapack) are among the largest single sources of battery demand in the world.
Tesla does not rely on a single cell supplier: it buys cells from Panasonic (its long-standing partner at Gigafactory Nevada), CATL and LG Energy Solution, using NCA, NMC and LFP chemistries across its range. It has also invested in its own cell development, notably the larger-format 4680 cylindrical cell, and in lithium refining.
Through its Megapack business, Tesla is also one of the world's largest suppliers of grid-scale energy storage, making it a major force on both the demand and supply sides of the battery economy.
