Which battery is no 1?
CATL (Contemporary Amperex Technology Co. Limited) is currently the world’s leading battery manufacturer, dominating global electric vehicle (EV) power battery installations. In Q1 2025, CATL maintained a 44.1% market share in China’s EV sector, with its lithium-ion battery technologies—including high-energy-density NMC and cost-effective LFP variants—powering over 50% of global EVs. Its vertical integration strategy and partnerships with automakers like Tesla and BMW solidify its position as the industry benchmark for innovation and scale.
Understanding the Difference Between UN3480 and UN3481 for Lithium Batteries
What technical advantages keep CATL at No.1?
CATL’s leadership stems from cell-to-pack (CTP) architecture and condensed-state battery technology, boosting energy density to 500 Wh/kg. Pro Tip: Their thermal runaway prevention systems enable 0% fire incidents in certified EV models.
CATL pioneered third-generation CTP designs that eliminate module housings, increasing volumetric efficiency by 20% compared to standard NMC packs. Their sodium-ion hybrid batteries (2025 release) solve lithium scarcity challenges while maintaining 160 Wh/kg performance. For instance, the Tesla Model Y Long Range uses CATL’s 72 kWh LFP pack, achieving 640 km range at 15% lower cost than NMC alternatives. Thermal management systems with microchannel cooling plates maintain optimal 25–35°C cell temperatures even during 3C fast charging.
| Technology | CATL | LGES |
|---|---|---|
| Energy Density | 500 Wh/kg | 450 Wh/kg |
| Fast Charge Rate | 4C | 2.5C |
How does CATL’s market share compare globally?
In Q1 2025, CATL held 36.7% global market share versus BYD’s 16.2% and LGES’ 13.8%. Their 206.9 GWh quarterly output powers 4.3 million EVs annually.
CATL’s dominance extends beyond passenger EVs—they supply 72% of China’s commercial vehicle batteries and 40% of global energy storage systems. Their German factory produces 14 GWh/year for European automakers, circumventing trade barriers. By comparison, second-place BYD focuses primarily on captive demand from its own vehicles.
| Region | CATL Share | Nearest Competitor |
|---|---|---|
| China | 44.1% | BYD (26.2%) |
| Europe | 31% | LGES (27%) |
Pro Tip: Investors monitor CATL’s quarterly R&D expenditure (6-8% of revenue) as a leading indicator of next-gen battery breakthroughs.
