CATL has officially unveiled the Naxtra Battery, claiming it to be the world’s first Sodium-ion Battery produced on a mass scale. The announcement at CATL‘s Super Tech Day marks a significant milestone in the energy industry, as Naxtra harnesses sodium’s natural advantages to push beyond resource constraints.
What Makes Sodium-Ion Batteries Unique?
Sodium-ion batteries offer a safer and more sustainable alternative to traditional Lithium-ion technology. Lithium extraction has faced scrutiny for its environmental impact, but sodium is abundant and easier to source. According to CATL, the Naxtra Battery lays the groundwork for energy freedom by reducing dependence on limited lithium reserves.
Naxtra Passenger EV Battery: Performance Redefined
CATL’s Naxtra Battery product line features two distinct models: the Naxtra passenger EV Battery and the Naxtra 24V Heavy-Duty Truck Integrated Start-Stop Battery. The passenger EV unit boasts an energy density of 175 Wh/kg, putting it on par with lithium iron phosphate (LFP) batteries and making it the highest energy density among sodium-ion batteries.
Designed for all-weather performance, the Naxtra Battery retains 90% usable power at -40°C and withstands heat up to 70°C. With a range of 500 kilometers and over 10,000 charging cycles, it reduces maintenance costs while ensuring reliability for electric vehicle users.
Naxtra Heavy-Duty Truck Battery
The second unit, Naxtra 24V Heavy-Duty Truck Integrated Start-Stop Battery, delivers unparalleled durability. Featuring an eight-year service life, it reduces lifecycle costs by 61% compared to traditional lead-acid batteries. CATL projects the heavy-duty battery to be more efficient, eco-friendly, and economical, ushering commercial vehicles into a lead-free era.
Safety and Energy Optimization
Safety is at the forefront of the Naxtra Battery’s design. CATL notes the system offers intrinsic safety features, transitioning from the “passive defense” approach seen in older battery technologies. This innovation ensures both user safety and consistent battery performance over time.
Shenxing Superfast Charging: A Step Beyond
In addition to the Naxtra line, CATL revealed the Shenxing Superfast Charging Battery. It features a peak charging power of 1.3 MW and achieves 2.5 kilometers of range per second of charging. The groundbreaking LFP system combines an 800-kilometer range with a 12C peak charging rate, minimizing charging wait times.
CATL’s commitment to energy storage innovation reinforces its role as a global leader in battery manufacturing. The Naxtra and Shenxing batteries not only enhance performance but also pave the way for sustainable and scalable energy solutions.
