Salt batteries are gaining ground in EVs and grid storage. In 2026, sodium-ion technology is moving from lab tests to real products. As a result, it is drawing attention from car makers, battery firms, and power companies. Unlike Lithium-ion cells, sodium-ion batteries use sodium, which is widely available and low in cost. That simple change could lower battery prices and expand energy storage at scale.
Why salt batteries matter for EVs and grid storage
Today, lithium-ion batteries still dominate the market. However, sodium-ion batteries are now entering commercial use. Their biggest appeal is cost. Sodium is abundant, and supply chains can become more flexible. Therefore, battery makers can reduce reliance on tighter raw material markets.
Salt batteries also perform well in cold weather. That advantage matters for Electric Vehicles in northern regions. It also helps grid storage systems in places with harsh winters. In one public demonstration on 5 February in northern China, a black sedan drove on an icy track at 95 kilometres per hour in temperatures of -32°C. During the test, a tyre burst and released a puff of white into the air. Even so, the vehicle stayed stable and coasted to a stop without spinning into the snow. That event aimed to show that extreme cold does not stop the new EV platform from operating safely.
Salt batteries in EVs: Changan and CATL move first
Changan is preparing one of the first mass-produced electric vehicles with a Sodium-ion Battery. The company’s Nevo A06 model is expected to reach the market later in 2026. CATL, one of the world’s largest battery makers, is supplying the new battery pack. Moreover, CATL is using a more powerful second-generation sodium-ion design for the launch.
This step matters because it moves sodium-ion batteries beyond pilot projects. Instead, it places the technology in a consumer vehicle from a major auto brand. That shift could speed up wider adoption across the EV sector. It also gives battery makers a practical path to diversify cell chemistry.
For drivers, the appeal is easy to understand. Lower battery cost can support more affordable electric cars. Strong cold-weather performance can also improve confidence in winter conditions. As a result, sodium-ion batteries may become a strong option for city cars, regional vehicles, and fleet transport.
Salt batteries for grid storage are a natural fit
Salt batteries also look well suited to grid storage. Power systems need large battery banks to store electricity from solar and wind projects. In that market, cost and scale matter most. Therefore, sodium-ion chemistry offers a practical advantage. Utilities can use abundant materials to build bigger storage systems more economically.
Grid operators also value stability across different climates. Since sodium-ion batteries handle low temperatures well, they can support projects in colder regions. In addition, their use of widely available sodium may help countries build local supply chains more easily. That can strengthen energy security while supporting the shift to cleaner power.
Because of these strengths, salt batteries may become especially important for stationary energy storage. They can help smooth renewable energy output, balance electricity demand, and support backup power systems. Consequently, they could play a larger role in modernizing power grids in 2026 and beyond.
How salt batteries compare with lithium-ion batteries
Lithium-ion batteries remain the leading choice for many premium EVs. They offer high energy density and a mature global manufacturing base. However, sodium-ion batteries bring a different set of benefits. They focus on affordability, material availability, and dependable performance in cold conditions.
That means the two chemistries do not need to compete in every segment. Instead, they can serve different needs. Lithium-ion may continue to power long-range vehicles. Meanwhile, salt batteries can support cost-sensitive EVs and large grid projects. This balanced approach could expand the whole battery market rather than replace one chemistry overnight.
The outlook for salt batteries in 2026
Salt batteries are no longer just an idea for the future. In 2026, they are entering real vehicles and attracting serious attention in energy storage. Changan’s upcoming Nevo A06 and CATL’s new sodium-ion cells show that major companies are ready to commercialize the technology. Furthermore, the public cold-weather test at -32°C and 95 kilometres per hour added a clear example of real-world performance.
As production grows, salt batteries could help lower EV costs and expand grid storage capacity. They rely on common materials, support flexible supply chains, and perform well in tough weather. For those reasons, sodium-ion technology is becoming one of the most important battery trends to watch this year.
