China's Battery Dominance: CATL, BYD, and Global EV Battery Leadership
China controls over 70 percent of the global EV battery manufacturing capacity, led by CATL (Contemporary Amperex Technology Co. Limited) and BYD's battery division. Chinese battery makers dominate not just cell production but the entire supply chain from raw material processing (lithium, cobalt, nickel) to recycling. The shift toward Lithium Iron Phosphate (LFP) chemistry, pioneered and optimized by Chinese companies, has further strengthened China's position as LFP batteries are cheaper, safer, and increasingly competitive in energy density with NMC alternatives.
TL;DR
CATL is the world's largest battery maker with 37 percent global market share. BYD ranks second with 16 percent. Together with other Chinese manufacturers, China controls over 70 percent of global EV battery production. Chinese dominance extends across the entire supply chain from raw material processing to cell manufacturing and recycling.
Key Insights
CATL Market Share
CATL shipped 259.7 GWh of batteries in 2024, maintaining its position as the world's largest battery manufacturer with approximately 37 percent global market share. CATL supplies Tesla, BMW, Mercedes-Benz, Volkswagen, Hyundai, and virtually every major automaker. The company's customers span over 50 countries and its batteries power approximately one in three EVs sold globally.
BYD Battery Division
BYD's battery division shipped 112.1 GWh in 2024 for a 16 percent global market share, ranking second worldwide. BYD primarily uses its proprietary LFP Blade Battery technology for its own vehicles but has begun supplying external customers. BYD recently announced plans to supply batteries to Tesla, Toyota, and other automakers, which would further increase its market presence.
LFP vs NMC
Lithium Iron Phosphate (LFP) batteries now account for over 60 percent of China's EV battery market, up from less than 40 percent in 2020. LFP offers lower cost (30-40 percent cheaper than NMC per kWh), superior safety, and longer cycle life. Chinese manufacturers have overcome LFP's traditional energy density disadvantage through cell-to-pack (CTP) and cell-to-body (CTB) innovations.
Supply Chain Control
China controls over 70 percent of global lithium processing, 80 percent of cobalt refining, and 90+ percent of graphite processing. Chinese companies including Tianqi Lithium, Ganfeng Lithium, and GEM dominate raw material processing. This upstream control, combined with manufacturing scale, gives China significant leverage over the global battery supply chain.
Next-Gen Technology
CATL launched the world's first commercially produced sodium-ion batteries in 2023, offering a cheaper alternative to lithium for stationary storage and budget EVs. Chinese companies are also leading solid-state battery development, with CATL, BYD, and QuantumScape-backed Nio all working on prototypes. CATL's condensed matter battery claims energy density exceeding 500 Wh/kg for aviation applications.
Battery Recycling
China has built the world's most advanced battery recycling infrastructure, processing over 50,000 tons of used batteries annually. Companies like Brunp Recycling (CATL affiliate), GEM, and Huayou Cobalt recover lithium, cobalt, nickel, and manganese from spent batteries at recovery rates exceeding 95 percent. Government mandates require automakers to establish recycling networks, creating a closed-loop supply chain.

Frequently Asked Questions
China's dominance stems from: (1) Early government policy support including subsidies for EVs and battery makers since 2009, (2) Massive domestic EV market providing guaranteed demand, (3) Control of raw material processing infrastructure, (4) Aggressive investment in manufacturing capacity with economies of scale, (5) Innovation in LFP chemistry that reduced costs dramatically, and (6) Integration of battery and vehicle manufacturing at companies like BYD.
BYD's Blade Battery is an LFP battery cell designed in an elongated blade shape that doubles as a structural component. This innovation increases pack energy density by eliminating module housings, improves safety through thermal stability, and reduces costs through simpler manufacturing. The Blade Battery passed the nail penetration test without fire, demonstrating superior safety over conventional NMC batteries. It has become a significant competitive advantage for BYD's vehicles.
Several countries and regions are trying: the US Inflation Reduction Act provides billions in battery manufacturing incentives, Europe is building gigafactories through Northvolt and Asian company subsidiaries, and Japan/Korea maintain strong positions in NMC technology. However, China's decade-long head start in scale, supply chain integration, and cost efficiency means catching up will take years. The US and EU are focused on reducing strategic dependency rather than fully displacing Chinese battery manufacturing.
