Global battery major CATL has introduced the world’s first mass-produced sodium-ion battery specifically developed for vans and light commercial vehicles, signaling a major shift in electric mobility technology. The new battery was unveiled as part of CATL’s latest Tectrans II product lineup aimed at commercial transportation.
The sodium-ion battery pack offers a capacity of 45 kWh and is designed to deliver stable performance in extremely cold environments. CATL said the battery can operate and charge efficiently at temperatures as low as minus 30 degrees Celsius, while maintaining nearly 90 percent usable power even at minus 40 degrees, addressing a key challenge faced by conventional lithium-ion batteries.
According to the company, the new technology significantly improves vehicle reliability and reduces range loss during winter operations. CATL stated that sodium-ion batteries are expected to play a growing role in commercial electric vehicles due to their strong low-temperature performance, safety advantages, and reduced dependence on lithium resources.
Alongside the sodium-ion offering, the Tectrans II series includes multiple battery variants tailored for different operating conditions. These include ultra-fast charging batteries capable of reaching 80 percent charge in about 30 minutes, high-temperature-resistant models for hot climates, and long-range battery packs with capacities of up to 253 kWh for extended driving requirements.
CATL also highlighted modular battery solutions within the lineup that support battery-swapping applications, enabling faster vehicle turnaround times for logistics and delivery fleets. The company said this flexibility will help fleet operators optimize costs while improving vehicle uptime.
Industry experts view CATL’s sodium-ion breakthrough as a step toward diversifying EV battery chemistries and strengthening supply chains. While sodium-ion batteries offer lower energy density than lithium-ion cells, their cost efficiency, safety profile, and performance in extreme climates make them well-suited for commercial vehicle applications.
