Changan and CATL Gear Up for Sodium Ion Battery Launch

Changan and CATL Gear Up for Sodium Ion Battery Launch

Changan and CATL Sodium Ion Battery launch signals a new era for Electric Vehicles and the global automotive market. Changan has announced a strategic partnership with CATL to unveil its Sodium-ion Battery plans on February 5. This event, taking place in Yakeshi, Inner Mongolia, marks the first large-scale rollout of Sodium-ion Battery technology in mass-market passenger vehicles. The announcement arrives amid growing interest in alternatives to Lithium-ion chemistry, which currently dominates the electric vehicle (EV) industry.

Sodium Ion Batteries: A New Chapter in Automotive Innovation

Changan’s move illustrates its commitment to sustainable innovation in electric mobility. The company’s Oshan sub-brand will be among the first to integrate CATL’s leading-edge sodium-ion batteries, specifically the Naxtra line, into its passenger car lineup. Additionally, other prominent Chinese automakers like GAC Group and Anhui Jianghuai Automobile Group plan to follow Changan’s example. CATL, which introduced its first-generation Sodium-ion Battery technology in July 2021, has continued to improve the design. The formal unveiling of the Naxtra brand in April 2025 highlights CATL’s dedication to advancing sodium-ion technology.

Innovative Features and Technical Specifications

CATL’s sodium-ion batteries offer several notable advantages for the EV market. The Tianxing II Sodium-ion Battery series, intended for light commercial vehicles, features an energy density of 175 Wh/kg. While this value remains lower compared to contemporary Lithium-ion batteries, which typically range from 230 to 275 Wh/kg, many automakers recognize the benefits of sodium-ion chemistry. Safety and cost advantages in particular contribute to growing interest.

Changan emphasizes the technology’s superior performance in extreme cold. Recent tests demonstrate that sodium-ion batteries can retain around 90% of their original capacity in temperatures as low as -40 degrees Celsius. In comparison, standard Lithium-ion batteries may lose between 60% and 90% of their capacity under the same conditions. This exceptional cold-weather resilience provides enhanced safety and reliability for drivers in challenging climates. Moreover, sodium-ion batteries possess a greater degree of thermal stability, which further reduces safety risks commonly associated with Lithium-ion cells.

The Economic and Environmental Advantages

Sodium metal is far more abundant than lithium, with availability estimates showing it is 500 to 1,000 times more prevalent. Extracting sodium from seawater is straightforward, inexpensive, and far less impactful on the environment when compared to conventional lithium mining operations. This abundance significantly reduces both price volatility and supply chain instability. In early 2026, sodium reportedly costs just US$600 per tonne, compared to over US$20,000 per tonne for lithium carbonate. As battery raw material prices continue to rise, these factors make sodium-ion batteries an attractive solution for large-scale manufacturing.

Scaling Up The Adoption of Sodium Ion Batteries

Changan’s collaboration with CATL will accelerate the widespread deployment of Sodium-ion Battery technology. Industry experts project large-scale use of these batteries in 2026. Applications will include battery-swapping systems, energy storage, commercial vehicles, and mainstream passenger vehicles. The batteries are expected to play a pivotal role in China’s expanding EV infrastructure, meeting both stringent safety standards and consumer expectations.

Strengthening Changan’s Competitive Edge

The adoption of sodium-ion batteries enhances Changan’s standing as a leader in automotive innovation. The company’s initiative showcases a commitment to affordable, clean, and reliable energy solutions for drivers worldwide. With its focus on high-performance batteries suitable for extreme environments, Changan is positioning itself at the forefront of next-generation electric mobility solutions.

As the partnership between Changan and CATL progresses, the Sodium-ion Battery launch will continue to attract global attention. The project underscores a shift in the global battery market, moving toward greater sustainability and economic stability. The automotive world will be closely watching Changan’s advances, eager to see how this game-changing technology shapes the future of Electric Vehicles.
