CATL (Contemporary Amperex Technology Co., Limited), founded in 2011 and headquartered in Ningde, China, focuses on lithium-ion batteries for electric vehicles and energy storage systems. By installed EV battery capacity, it remained the world’s largest supplier in 2024 with about 38% global share, based on SNE Research data reported by multiple outlets.
CATL positions itself as a new-energy technology company providing battery solutions and services for mobility and stationary storage. It supplies major automakers including Tesla, BMW, Volkswagen, Toyota, and others, which makes it a core upstream partner in the EV supply chain.
International expansion is moving from exports to local manufacturing. CATL began operations at its first overseas cell plant in Thuringia, Germany in early 2023, and its Debrecen, Hungary gigafactory is expected to start serial production in spring 2026. Proceeds from CATL’s 2025 Hong Kong listing were directed in part toward funding the Hungary build-out.
