A new sodium-ion battery breakthrough means they may one day power EVs
Sodium-ion batteries have great promise. They're energy dense, nonflammable, and operate well in colder temperatures, and sodium is cheap and abundant. Plus, sodium-based batteries will be more environmentally friendly and even less expensive than lithium-ion batteries are becoming now. Sodium-ion battery performance has been limited because of poor durability, but this is about to change for the better.
