KATHMANDU: China has started testing sodium-ion battery technology in heavy-duty electric trucks as manufacturers look for alternatives to lithium-ion batteries. Truck maker FAW Jiefang has completed real-world testing of sodium-powered electric trucks under different weather and operating conditions.
The test lasted nearly seven months and covered more than 15,000 km. The company monitored the trucks during regular commercial-style operations, including long-distance routes, frequent charging, and changing road conditions.
FAW Jiefang’s electric semi-trucks used a 339 kWh sodium-ion battery pack developed with battery supplier Zhongke Haina. During testing at temperatures as low as -40°C, the battery retained more than 90% of its usable capacity.
The company said the sodium-ion battery also showed faster charging capability and improved safety performance. The battery can reportedly achieve a full charge in around 20 to 25 minutes under suitable conditions.
The battery pack has a cycle life of more than 8,000 charging cycles under fast charging conditions, according to Zhongke Haina. The company said sodium-ion technology offers better thermal stability and can suit commercial vehicles requiring high-frequency operation.
Sodium-ion batteries use more abundant materials than lithium-ion batteries, which could help reduce battery costs. Chinese manufacturers are now focusing on improving performance and bringing the technology into commercial applications.
Companies including CATL and BYD are also developing sodium-ion battery technology. The industry is exploring sodium batteries as a potential alternative for electric vehicles, especially in cost-sensitive and heavy-duty segments.
