CATL’s Sodium-Ion Battery Promises Longevity and Cold-Weather Resilience
- CATL unveiled a sodium-ion battery capable of up to 15,000 cycles and a lifespan of up to 20 years.
- The battery aims for electric vehicles (EVs) with a range of up to 600 km, even in cold climates.
- The “One Shell, Two Cells” design allows interchangeable use of sodium and lithium packs, reducing platform costs.
- Wanhua Chemical supports the use of synthetic carbon anodes from domestic coal, lowering dependency on imported materials.
- Third-party tests will validate the battery’s cold-weather performance claims prior to its planned rollout in 2026.
CATL’s new sodium-ion battery technology could significantly impact the EV market by offering long-lasting batteries that perform well in cold conditions, addressing common issues faced by lithium-ion cells. The hybrid design also provides flexibility for manufacturers looking to balance cost and performance.
If successful in third-party testing, CATL’s sodium-ion batteries could push EVs with ranges up to 372 miles into mainstream markets without relying heavily on lithium resources. (Source)
