A cheaper, safer, and more abundant alternative to lithium is finally making its way into cars—and the grid.

And the technology is already making it into cars. In 2024, JMEV began offering the option of buying its EV3 vehicle with a sodium-ion battery pack. HiNa Battery is putting sodium-ion batteries into low-speed EVs.

The new batteries are also being tested in smaller electric vehicles. In China, the scooter maker Yadea launched four models of two-wheelers powered by the technology in 2025, as cities including Shenzhen started piloting swapping stations for sodium-­ion batteries to support commuters and delivery drivers.
