CATL Naxtra – the world’s first mass-produced sodium-ion (NA+) battery
Innovation in Sodium-Ion Technology also known as Na+
CATL’s Naxtra Battery is a major advancement in battery technology. It is the first to successfully produce sodium-ion batteries on a large scale. These batteries are safer and more abundant than traditional lithium-ion batteries, reducing our reliance on lithium and supporting a more diverse energy future.
Performance in Extreme Temperatures
the Naxtra Battery line includes two types: one for electric passenger vehicles and another for heavy-duty trucks. Both can operate in temperatures ranging from -40°C to +70°C, making them highly versatile. The passenger EV battery retains 90% of its power at -40°C and performs well even when the charge is very low.
Efficiency and Longevity
The Naxtra passenger EV battery (Na+ Traction) has an energy density of 175Wh/kg, which is the highest for sodium-ion batteries and similar to LFP batteries. It can travel up to 500 kilometers on a single charge and lasts over 10,000 cycles, reducing maintenance needs. It is also safer, as it eliminates factors that support combustion, moving from passive to intrinsic safety.
Benefits for Heavy-Duty Trucks
The Naxtra 24V battery (pictured above) for heavy-duty trucks lasts over 8 years and cuts total costs by 61% compared to traditional lead-acid batteries. It offers deep discharge capabilities, easy starting at -40°C, and can start even after a year of inactivity. This makes it more efficient, eco-friendly, and cost-effective, helping to phase out lead-acid batteries in commercial vehicles.
Wider Applications
CATL’s advancements in sodium-ion batteries now allow for better performance in very cold conditions. This breakthrough is crucial for using batteries in all scenarios, pushing the boundaries of battery technology and applications.
