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.
