CATL, founded in 2011 in Ningde, China, is the largest battery manufacturer in the world and the only one to hold more than 30% of the global EV battery market. It supplies automakers including Tesla, Ford, and Volkswagen, with production bases in China, Germany, and Hungary.

Chinese, South Korean, and Japanese companies dominate lithium-ion battery cell production, with China alone accounting for well over 80% of all batteries manufactured. The sector serves electric vehicles — which represent more than 70% of total lithium-ion battery deployment — along with energy storage systems, consumer electronics, and industrial equipment.

Key players among the largest battery manufacturers include:

• CATL — Listed in Shenzhen and Hong Kong, the global market share leader in EV batteries.
• BYD — A vertically integrated company listed in Hong Kong, active across electric vehicles, electronics, and renewable energy.
• LG Energy Solution — Established as an independent entity in 2020 after separating from LG Chem, listed in South Korea, with global joint ventures across automakers.

Two main chemistries define the market: Nickel Manganese Cobalt (NMC) batteries hold the largest global share, while Lithium Iron Phosphate (LFP) is the fastest-growing chemistry thanks to its lower cost and longer lifetime. Solid-state batteries represent the next frontier, with several listed companies actively developing them. For related sectors, see lithium mining companies.
