Changan Oshan has made headlines by adopting advanced sodium-ion batteries developed by CATL, marking a significant milestone in the electric vehicle (EV) sector. According to reports from Chinese media, CATL’s Sodium-ion Battery brand, Naxtra, has been deployed in passenger car models, starting with Changan Oshan vehicles. This pioneering step comes as CATL continues to expand the applications of its sodium-based technology.
CATL‘s Sodium-Ion Innovations
CATL first announced its Sodium-ion Battery technology in 2021, aiming to offer alternatives to Lithium-ion solutions. In April 2025, the company launched the Naxtra brand, dedicated to sodium-ion batteries, which now boast an energy density of 175 Wh/kg—comparable to widely used lithium iron phosphate (LFP) cells. These batteries promise reliable performance even in extreme conditions, with standout features like functionality at -30°C and retention of 90% capacity at -40°C. Such advancements pave the way for broader adoption in passenger vehicles.
CATL recently unveiled its “Tectrans II” series of batteries, which feature a 45 kWh Sodium-ion Battery designed for light commercial vehicles such as vans and small trucks. These batteries are engineered for quick charging, even in colder climates. Additionally, they boast a lifespan exceeding 10,000 cycles, showcasing impressive durability.
Changan Oshan and Other Adopters
While CATL’s sodium-ion batteries initially targeted light commercial vehicles, they are now entering the passenger car market. The Changan Oshan 520 is reportedly the first model equipped with these batteries. Additionally, models from GAC and JAC are expected to follow suit, further validating this technology’s compatibility with diverse vehicle categories.
An interesting feature of the Changan Oshan 520 is its integration with a battery-swapping system from CATL. This technology could reduce charging times and enhance usability, making EVs more practical for everyday use. Although other industry players, like the JAC-owned Yiwei brand, have previously released cars with sodium-ion batteries, CATL’s entry into this space as a global leader is significant.
Sodium-Ion’s Promising Advantages
According to Gao Huan, CATL’s Chief Technology Officer, sodium-ion batteries could dramatically reshape the EV market. The technology offers several unique advantages, such as robust performance in extremely cold climates and inherent safety features. Moreover, its accelerated development pace suggests sodium-ion batteries could soon reach parity, or even surpass, Lithium-ion batteries in certain applications.
Changan Oshan’s adoption represents a critical validation of sodium-ion technology for passenger cars. As the industry leader in energy storage solutions, CATL’s involvement is expected to fuel further momentum for sodium-ion adoption in EVs. Collaborative advancements will likely play a role in shaping the future of electric transportation.
Conclusion
Changan Oshan’s integration of CATL’s sodium-ion batteries marks a new chapter for eco-friendly mobility. With key models such as the Oshan 520, GAC, and JAC leveraging this technology, sodium-ion batteries are set to emerge as a viable alternative in the EV market. Their reliability, safety, and resilience make them a promising addition to the global shift toward sustainable transportation. The success of these early implementations could lay the foundation for broader adoption, driving innovation in the automotive and battery industries alike.
