China, May 16, 2025: Contemporary Amperex Technology Co. Ltd. (CATL) has commenced mass production of its sodium-ion batteries under the Naxtra brand, positioning them as a viable alternative to lithium-ion technology. This move aims to reduce reliance on lithium resources and foster greater energy independence.
The Naxtra battery, designed for electric vehicles (EVs), offers a range of up to 310 miles (500 km). These batteries are engineered for safe operation across a broad temperature range, from -40 to 178 degrees Fahrenheit (-40°C to +70°C). They also retain 90% of their usable power even at -40°C. The Naxtra EV battery boasts over 10,000 cycles, potentially equating to 3.6 million miles before significant capacity loss.
A 24-volt version of the Naxtra battery is available as a replacement for lead-acid batteries in combustion engine vehicles. It features an eight-year lifecycle and a 61% reduction in cost. Designed for vehicles with frequent start-stop systems, it can start even after a year of idleness. CATL's advancements also include large-scale sodium-ion stationary storage units, with one already powering 12,000 homes daily in China.
