Three Chinese firms, BYD, Chery and JAC, plan on releasing these next-generation sodium-ion cars for public sale later this year.
Downside of sodium batteries is shorter range of 200 to 300 kilometres compared to 300 and 500 for lithium batteries. That’s perfect for people whose main journeys are to work or school or to nearby towns, but who don’t make road trips across the country.
Once they solve the density problem with sodium batteries, they will be so much better than lithium alloy.
