With 2024 revenue exceeding $55 billion and plans for next-generation all-solid-state batteries by 2027, CATL is the backbone of the global EV transition.
TL;DR
CATL holds 37% global EV battery market share, supplies Tesla/BMW/VW/Mercedes, generated $55B+ revenue in 2024, and is developing next-gen solid-state batteries for 2027.
Key Insights
Global Market Share
CATL maintained approximately 37% of the global EV battery market in 2024, up from 36% in 2023. The company's nearest competitor, BYD, holds around 16%. CATL's dominance extends across all regions — China (45%), Europe (35%), and growing in North America.
2024 Revenue
CATL's 2024 revenue exceeded $55 billion (400+ billion CNY), with net profit reaching approximately $7 billion. Revenue grew 20%+ year-over-year, driven by strong demand from global automakers and increased average selling prices for premium battery products.
Qilin Battery
CATL's Qilin battery uses cell-to-pack (CTP) 3.0 technology, achieving 255 Wh/kg energy density — among the highest for production LFP batteries. It enables 1,000 km range in a standard sedan and supports 4C superfast charging (10-80% in 10 minutes).
Major Customers
CATL supplies batteries to nearly every major global automaker. Key partnerships include Tesla (standard-range Model 3/Y), BMW (iX, i4), Mercedes-Benz (EQ series), Volkswagen (ID series), Hyundai (Ioniq), and Ford (F-150 Lightning). CATL also works with Li Auto, NIO, and XPeng.
Sodium-Ion Battery
CATL began mass-producing sodium-ion batteries in 2023, offering a low-cost alternative for affordable EVs. Sodium-ion batteries cost 30-40% less than LFP, perform better in cold temperatures, and use abundant sodium instead of scarce lithium.
Solid-State Battery Plans
CATL plans to mass-produce all-solid-state batteries by 2027, promising 500+ Wh/kg energy density (double current LFP), 1,500 km range, and superior safety. Semi-solid-state prototypes already achieve 400 Wh/kg in testing.

Frequently Asked Questions
Yes, CATL is a major Tesla battery supplier, particularly for standard-range Model 3 and Model Y vehicles produced at Tesla's Shanghai Gigafactory. CATL provides LFP (lithium iron phosphate) cells, which offer lower cost, longer lifespan, and improved safety compared to NMC cells used in long-range models.
The Qilin battery is CATL's latest CTP (Cell-to-Pack) 3.0 technology, achieving 255 Wh/kg energy density for LFP chemistry. It integrates the battery cells directly into the pack without modules, increasing volume utilization to 72%. It supports 4C superfast charging (10-80% in 10 minutes) and enables 1,000 km driving range.
CATL plans to begin mass production of all-solid-state batteries in 2027. Semi-solid-state prototypes currently achieve 400 Wh/kg in testing. Full solid-state batteries promise 500+ Wh/kg, 1,500 km range, enhanced safety, and faster charging. Several automakers have signed agreements for early adoption.
CATL is the independent market leader (37% share) supplying multiple automakers, while BYD makes batteries primarily for its own vehicles (16% share). CATL leads in energy density and fast-charging technology (Qilin), while BYD's Blade Battery is praised for safety and is cost-effective. CATL offers more battery chemistry options (LFP, NMC, sodium-ion).
CATL's sodium-ion batteries use abundant sodium instead of lithium, reducing material costs by 30-40%. They perform better in cold temperatures (-20C vs -10C for LFP), have 200+ Wh/kg energy density, and 2,000+ cycle life. They're ideal for affordable EVs, energy storage, and two-wheelers where cost matters more than maximum range.
