Frequently Asked Questions
How much of the global EV battery market does China control?
China controls over 65% of global EV battery production, led by CATL (37% global share) and BYD (15% global share). Chinese battery companies dominate the supply chain from raw material processing (lithium, graphite) to cell manufacturing and battery pack assembly.
What is BYD's Blade Battery?
BYD's Blade Battery is an LFP (lithium iron phosphate) battery cell arranged in a long, thin blade shape. This design improves space utilization by 50%, passes nail penetration tests without fire, and achieves 1.2M+ km cycle life. It is considered the safest mass-produced EV battery.
What are China's next-generation battery technologies?
Key next-gen technologies include: CATL's condensed matter battery (500 Wh/kg, shipping 2025), semi-solid-state batteries by Gotion (360 Wh/kg, 2026), BYD's sodium-ion batteries for budget EVs (2025), and silicon-carbon anode cells by Farasis (330 Wh/kg).
Why are sodium-ion batteries important?
Sodium-ion batteries use abundant and cheap sodium instead of lithium, reducing raw material costs by 30-40%. They perform better in cold temperatures than LFP cells. CATL and BYD are commercializing sodium-ion batteries for budget EVs and energy storage, targeting sub-RMB 50,000 vehicles.
How fast can Chinese EV batteries charge?
CATL's Shenxing battery charges from 0-80% in 10 minutes (4C charging rate), enabling 400km range from a 10-minute charge. BYD's fast-charging LFP achieves similar speeds. These superfast-charging batteries use advanced electrolyte formulations and improved electrode architectures.
