The landscape for sodium-ion batteries is evolving, with promising applications emerging in areas where their specific advantages can be leveraged. While lithium-ion remains the dominant force, sodium-ion technology is finding its footing in niche markets.

Micromobility sector Embraces Sodium-Ion

Electric micromobility vehicles, such as scooters and three-wheelers, present a important prospect for sodium-ion batteries. These vehicles typically operate over shorter distances and at lower speeds compared to cars,making the lower energy density of sodium-ion batteries less of a limitation.

“It’s early days, but it’s interesting to see this market emerging.”

for example,the BBC recently highlighted the efforts of the Chinese company Yadea to integrate sodium-ion batteries into electric scooters. Yadea, a major player in the electric two- and three-wheeler market, has already launched several sodium-powered models, selling approximately 1,000 units in the first quarter of 2025, according to the company’s statement to the BBC. This demonstrates the early adoption and potential of sodium-ion batteries in this sector.

Stationary Energy Storage Gains Traction

Sodium-ion batteries are also making notable strides in stationary energy storage, including grid-scale installations. In these applications,the energy density of the battery is less critical,as the battery does not need to be moved or fit within the size constraints of a vehicle.

The Baochi Energy Storage Station in Yunnan province, China, exemplifies this trend. This facility utilizes a hybrid system combining both lithium-ion and sodium-ion batteries, boasting a total capacity of 400 megawatt-hours. Similarly, Natron Energy in the US is targeting data centers and other stationary storage customers with its sodium-ion battery solutions.

While micromobility and stationary storage represent the initial successes for sodium-ion batteries, some companies are still pursuing their use in electric vehicles. CATL,a leading Chinese battery manufacturer,has announced plans to produce sodium-ion batteries for heavy-duty trucks under the brand name naxtra Battery.

Despite the dominance of lithium in the battery industry, sodium-ion batteries can secure a foothold by focusing on applications where their characteristics are well-suited. This diversified approach to battery technology is crucial to meeting the growing energy storage demands across various sectors.
