Sodium-ion batteries are entering the fast lane in China’s new energy market. In 2026, this battery technology is moving from pilot programs to scaled deployment. Moreover, it is expanding from passenger vehicles into commercial trucks, starting batteries, and energy storage systems. That shift shows a clear commercial path for sodium-ion batteries across several high-value applications.
Sodium-Ion Batteries Gain Speed in 2026
2026 stands out as a key year for sodium-ion batteries in China. Early in the year, Changan Automobile and CATL introduced a sodium-ion strategy in Yakeshi. Soon after, HiNa Battery presented a full product matrix in Wuhan. This lineup covered starting batteries, energy storage products, and traction batteries.
These launches matter because they moved the conversation beyond theory. Instead, companies backed their claims with test results, product data, and commercial use cases. As a result, sodium-ion batteries now look ready for broader adoption in transport and energy applications.
Sodium-Ion Batteries Expand From Passenger Vehicles to Commercial Use
HiNa Battery released new operating data on March 31. The company shared results from commercial tests in three locations using sodium-powered heavy trucks. These tests focused on real operating conditions. They measured low-temperature range, mixed-road performance, climbing ability, charging speed, energy efficiency, and cycle life.
Commercial vehicles need batteries that can perform in demanding environments. Therefore, sodium-ion batteries offer an attractive option for heavy trucks, mining trucks, light commercial vehicles, and construction machinery. In northern China and high-altitude regions, low temperatures often shape vehicle performance. Sodium-ion technology shows strong results in these conditions.
According to HiNa Battery, its “Seastar” sodium-ion cells support operation from -40°C to 60°C. In addition, they retain more than 90% discharge capacity at -20°C. The cells also deliver a fast-charging cycle life of more than 8,000 cycles. For heavy-duty operations, that long life adds practical value. The cells can also provide one-key starting at -40°C, which supports heavy-load starts on complex terrain.
HiNa Battery also reported that sodium-ion batteries consume about 15% less energy per kilometer than Lithium-ion batteries. Furthermore, their strong depth of discharge can increase range by about 20% in typical scenarios with the same battery energy. Because sodium-ion batteries also support stronger regenerative power, they can deliver even better efficiency on complex roads.
Sodium-Ion Batteries in Starting, Storage, and Traction
HiNa Battery highlighted commercial progress in three major areas. These include starting batteries, energy storage, and traction systems. To support these segments, the company launched four products. The lineup includes a 10Ah cylindrical starting battery, two energy storage batteries, and one traction battery for commercial heavy trucks.
This broad portfolio shows how sodium-ion batteries can serve more than one market. On one hand, they fit vehicle applications. On the other hand, they also support stationary energy storage. That flexibility strengthens their commercial appeal in 2026.
Sodium-Ion Batteries Enter Passenger Vehicles
Passenger vehicles also mark an important step for sodium-ion batteries. In February, Changan Automobile and CATL unveiled a global sodium strategy. At the same time, they introduced the world’s first mass-produced passenger vehicle powered by a Sodium-ion Battery.
The vehicle uses CATL’s “Naxtra” battery. Test data shows that the battery meets user needs in winter conditions. Its cell energy density reaches 175 Wh/kg, which places it among the leading figures in the sector. Combined with CATL’s third-generation CTP technology, the battery enables a pure electric range of more than 400 kilometers.
As the supply chain matures, future versions may extend that range to 500 or even 600 kilometers. That level would cover more than 50% of current market demand. Therefore, sodium-ion batteries are becoming increasingly relevant for mainstream passenger vehicle use.
Low-temperature performance remains another strong selling point. At -30°C, discharge power is nearly three times higher than that of comparable LFP vehicles. Capacity retention exceeds 90% at -40°C. In addition, the battery can maintain stable discharge even at -50°C. Safety performance also stands out. Under extreme abuse tests, including drill penetration and sawing, the battery showed no ignition or explosion.
Changan plans to extend this battery technology across several brands, including AVATR, DEEPAL, and NEVO. Meanwhile, CATL plans to support this rollout with its battery-swapping network. By 2026, the company aims to deploy more than 3,000 Choco-Swap stations across over 140 cities.
Why Sodium-Ion Batteries Are Winning Attention
Sodium-ion batteries are gaining momentum for several clear reasons. First, sodium is abundant and widely available in the earth’s crust. That gives the technology a stable raw material base. Second, growing scale can lower costs over time. This makes sodium-ion batteries attractive for cost-sensitive sectors such as starting batteries and energy storage.
Third, sodium-ion batteries perform well across a wide temperature range. That feature supports adoption in cold regions, high-altitude areas, and heavy-duty commercial operations. In addition, strong safety performance and long cycle life add value in both mobility and storage markets.
Policy support also helps. China’s 15th Five-Year Plan and related industry goals encourage the large-scale application of new energy commercial trucks. At the same time, energy authorities support long-life, wide-temperature, low-degradation sodium batteries. As a result, leading companies such as CATL and HiNa Battery can build faster across materials, cells, and end-use applications.
The Commercial Outlook for Sodium-Ion Batteries
Sodium-ion batteries are no longer limited to research labs or small pilot projects. Instead, they are moving into passenger vehicles, commercial trucks, starting batteries, and energy storage systems. Strong figures support this progress, including 175 Wh/kg energy density, over 400 kilometers of range, more than 8,000 cycles, operation from -40°C to 60°C, and over 90% capacity retention in severe cold.
In short, sodium-ion batteries are building a solid commercial ecosystem in 2026. They offer strong low-temperature performance, high safety, long life, and improving economics. Therefore, as adoption grows across passenger and commercial vehicles, sodium-ion batteries are becoming one of the most important technologies in the next stage of clean mobility and energy storage.
