Battery titan CATL is officially betting on sodium to break the ice for electric transport. At a major launch event this past Thursday, the company unveiled its Tectrans II series, a new lineup of power batteries specifically designed to push light commercial vehicles like small vans and micro-trucks into the mainstream.
The standout star of the show is the series’ low-temperature variant, which CATL identifies as the industry’s first mass-produced sodium-ion battery for this sector. Built to survive the world’s harshest winters, the 45 kWh sodium battery pack is a direct answer to the “range anxiety” often felt in freezing climates.
Beating the Deep Freeze
Traditional lithium batteries often struggle when the mercury drops, but CATL’s new sodium technology is built for the “extreme cold.” The company shared impressive performance stats, noting that the battery remains functional and can be charged even at -30°C. Most notably, at –40°C, the battery still holds onto 90% of its usable capacity.
This move signals a strategic shift for the manufacturer. During a supplier conference at their Ningde headquarters on December 28, CATL leadership predicted that 2026 would be the year sodium batteries see “large-scale adoption.” They expect the technology to become a staple in passenger cars, commercial fleets, energy storage, and battery-swapping networks.
“Sodium-ion batteries and lithium-ion batteries are poised to form a ‘dual-star’ trend,” the company stated, highlighting a future where both chemistries work side-by-side to power the world.
A Battery for Every Scenario
While sodium took center stage for cold-weather performance, the Tectrans II series includes several other heavy-hitters designed for different commercial needs:
- The Speed Demon: An ultra-fast charging version that can jump from 20% to 80% in just 30 minutes, even at -15°C.
- The Heat Seeker: A high-temperature variant that adds 60% of its range in 18 minutes and boasts a massive 5,000-cycle lifespan at 45°C.
- The Long-Hauler: A high-capacity 253 kWh pack capable of delivering an 800-kilometer range on a single charge.
- The Swappables: New modular blocks (capacities of 42 kWh, 56 kWh, and 81 kWh) designed for rapid battery-swapping stations.
By diversifying its tech, CATL is making a clear case: whether you’re driving a micro-van through an Arctic winter or a long-haul truck across a sun-scorched highway, there is now a specific battery chemistry ready to do the job.
