CATL Sodium-Ion Batteries in Passenger Vehicles
CATL sodium-ion batteries are making their mark in the passenger vehicle industry. CATL, the world’s largest battery manufacturer, has announced the arrival of its sodium-ion technology in mass-market cars starting July. This move comes after much anticipation about the launch timeline and the performance of sodium-ion batteries in real-world vehicles.
GAC Aion Launches with CATL Sodium-Ion Batteries
According to CATL CTO Gao Huan, GAC Aion will become the first passenger vehicle equipped with CATL sodium-ion batteries to enter mass production. Production will begin in July. Furthermore, JAC Motor has already completed winter testing of sodium-ion batteries in their light trucks and mid-sized vans. This development marks a significant step for sodium technology’s commercial use beyond just prototypes or small test runs.
Expanding Applications for CATL Sodium-Ion Batteries
The launch of sodium-ion batteries in passenger vehicles represents only part of CATL’s broader strategy. CATL plans to expand these batteries into diverse fields. These include not only passenger vehicles, but also construction machinery and large-scale energy storage solutions. The versatility of sodium-ion batteries positions them as a promising alternative chemistry within the battery sector, especially as demand for electric mobility and renewable storage grows globally.
Performance and Innovations: CATL Tectrans Battery System and NaXtra
CATL recently introduced the Tectrans battery system, which delivers energy solutions for a broad range of light commercial vehicles. For the first time, CATL showcased a 45 kWh Sodium-ion Battery pack designed specifically for light commercial use. This innovative pack can charge efficiently at temperatures as low as -30°C, and it maintains up to 90% of its rated capacity even in -40°C weather. These features make it particularly suited for markets and vehicles that experience extreme climates.
In addition, CATL’s advancements include special battery pack variants for high-speed charging at temperatures as low as -15°C. The company has also revealed a 253 kWh pack intended for vehicles with long-range requirements, capable of supporting up to 800 km per charge. Their lineup includes modular swap packs available in 42, 56, and 81 kWh sizes. At its April 2025 tech day event, CATL unveiled the third-generation sodium-ion NaXtra series, which achieves an energy density of 175 Wh/kg. This level of energy storage positions sodium-ion batteries as a reliable and flexible option for many light- and mid-duty commercial applications.
Sodium-Ion Adoption Accelerates Globally
Alongside CATL, several other major battery companies, such as BYD and HiNa in China and Unigrid in Europe and the United States, have entered Sodium-ion Battery manufacturing. These market players recognize sodium-ion technology as a strong alternative, especially with lithium prices climbing again. CATL’s choice to commercialize sodium-ion batteries in mass-market vehicles not only increases industry focus on this technology but also demonstrates its capabilities in performance and reliability.
Conclusion: A New Era for CATL Sodium-Ion Batteries in Vehicles
The introduction of CATL sodium-ion batteries in passenger vehicles signals a shift in the electric vehicle battery landscape. With mass production starting in July and proven performance in extreme climates, sodium-ion technology is set to play a pivotal role in the next wave of Electric Vehicles. The ongoing innovation and expanding applications underscore CATL’s leadership in developing cutting-edge battery solutions for various mobility and energy needs.
