Another sodium-ion EV battery breakthrough emerges in China with 4C fast charging in 11 mins
Why it matters: China's sodium-ion battery breakthroughs promise cheaper, safer EVs with extreme fast charging and wider temperature resilience.
- BAIC Group announced a "significant breakthrough" with its sodium-ion battery prototype, achieving an energy density over 170Wh/kg and 4C ultra-fast charging in approximately 11 minutes.
- BAIC's sodium-ion battery demonstrates robust performance, maintaining over 92% energy retention at -20°C and operating effectively from -40°C to 60°C.
- CATL previously showcased its "Naxtra" sodium-ion batteries with an energy density up to 175 Wh/kg, already powering the Changan Nevo A06 with a 45-kWh pack for up to 400 km range.
- Both BAIC and CATL are contributing to the rapid mass production of sodium-ion batteries, with CATL's chief tech officer highlighting their resilience, wider operating temperature range, and sustainable growth for electrification.
- Sodium-ion batteries are seen by manufacturers like CATL and BYD as a crucial, lower-cost alternative to lithium, combating rising lithium prices and driving projected global shipments to over 1,000 GWh in the next four years.
China is rapidly advancing sodium-ion battery technology for EVs, with BAIC Group unveiling a prototype capable of 4C fast charging in 11 minutes and maintaining performance across extreme temperatures. This follows CATL's recent launch of the world's first mass-produced EV with a sodium-ion battery, signaling a significant shift towards more affordable, safer, and efficient EV power sources.
