Yes, some cars are starting to use sodium-ion batteries, but they are still in the early stages of commercial adoption. Here's a summary of what's happening:
BYD, Dongfeng, and others have invested or partnered with sodium-ion battery developers like Farasis, HiNa, and CATL.
-
Vehicles may begin using sodium-ion batteries in entry-level or hybrid models by 2025–2026.
Why Sodium-Ion Batteries in Cars?
Advantages:
-
Cheaper than lithium-ion (no lithium, cobalt, or nickel)
-
Safer (less prone to fire or thermal runaway)
-
Better performance in cold weather
-
Abundant raw materials (easier to scale production)
Limitations:
-
Lower energy density (~100–160 Wh/kg vs. 180–270+ Wh/kg in Li-ion)
-
Shorter range (not ideal for long-distance EVs yet)
Outlook
-
Sodium-ion batteries are most likely to appear in low-cost EVs, small city cars, or hybrid electric vehicles first.
-
They're also a strong candidate for energy storage systems (ESS), where size and weight are less critical.
