First Sodium-ion Battery with a 300-mile range has been unveiled by CATL, marking a significant moment in electric vehicle technology. CATL, the world’s largest battery maker, has introduced its Naxtra Sodium-ion Battery line, designed for passenger EVs.
Record Energy Density and Extreme Durability
CATL’s new Naxtra batteries feature second-generation sodium-ion cells with an impressive energy density of 175 Wh/kg. This matches the levels of lithium iron phosphate (LFP) batteries commonly used in top-tier electric cars today. Along with this high energy density, the batteries maintain remarkable durability. Naxtra sodium-ion cells can retain their capacity across 10,000 charge cycles and even perform reliably in freezing temperatures as low as -40 degrees Celsius.
Advantages Over Lithium Batteries
Compared to lithium-based alternatives, sodium-ion batteries boast several benefits. One notable advantage is their cost-effectiveness. While lithium prices fluctuate, sodium-ion batteries remain competitive. They feature a non-flammable composition, enhancing intrinsic safety. This makes them resistant to punctures, smashing, and fires—offering peace of mind to manufacturers and consumers alike.
Mass Production Timeline
CATL plans to commence mass production of sodium-ion packs for heavy-duty vehicles, like trucks, in June. This move aims to replace traditional lead-acid batteries while cutting costs by approximately half. In December, CATL will release its 300-mile Naxtra battery packs for passenger EV manufacturers. These batteries are expected to power upcoming models from leading electric vehicle brands.
Making EVs More Accessible
Besides being cost-effective, CATL’s technology opens new doors for EV performance. Sodium-ion batteries are particularly suited for colder climates where lithium batteries traditionally struggle. With this innovation, electric cars powered by sodium-ion packs can operate efficiently in sub-zero temperatures without pre-warming batteries.
A Historic Launch
The global introduction of sodium-ion batteries marks a transformative shift for the EV industry. These batteries combine safety, durability, and affordability, ensuring Electric Vehicles become increasingly accessible. CATL‘s rigorous testing showcases the packs enduring extreme scenarios, proving their reliability for real-world use. With Naxtra sodium-ion batteries, passenger vehicles will enjoy extended range and improved resilience—all while lowering costs for manufacturers and consumers.
CATL’s advances solidify its status as a leader in energy storage innovation. As the company begins shipping the batteries globally, sodium-ion cell technology may soon become a standard for the next generation of electric cars. This development paves the way for more sustainable and affordable EVs in the future.
