Optimizing electric vehicle batteries has been a key challenge for manufacturers.
Changan Automobile and CATL, the world's largest battery manufacturer, have introduced the first-ever sodium-ion (Na-ion) electric vehicle, the Changan Nevo A06. This innovation promises safer battery technologies and enhanced cold-weather performance.
The Nevo A06 features a 45 kWh CATL Naxtra battery, capable of delivering 248 miles (400 kilometers) on a single charge. These Na-ion cells boast an energy density of 175 watt-hours per kilogram.
CATL reports that the Na-ion batteries can charge to 80% in just 15 minutes, significantly faster than traditional lithium-ion batteries. This rapid charging capability offers consumers an experience akin to refueling with gasoline.
The Changan Nevo A06 is slated for a mid-2026 launch, signaling a wave of upcoming Na-ion EVs. BYD is also investing heavily in this technology, with a new 30 gigawatt-hour Na-ion battery facility under construction in China.
Na-ion batteries are poised to reduce manufacturing costs and improve safety. Made from abundant sodium, they are more stable and less prone to fire than lithium-ion alternatives. Furthermore, their superior performance in extreme temperatures-retaining charge at -40 degrees Fahrenheit-ensures better year-round EV efficiency.
Changan stated the Nevo A06 retains three times more discharge capacity at -22 degrees F than lithium iron phosphate batteries, a leading EV technology, at comparable capacities.
