They have lower energy density and only have limited use now:

China’s biggest maker of electric vehicle batteries (also known as CATL) is setting up a supply chain for the batteries and has entered into negotiations with some automakers about their use.

The technological limitations of sodium-ion batteries, according to Pacific Securities Co. Ltd analysts, have mostly seen their use confined to e-bikes and energy storage.

But since their lithium-based counterparts are so widely used and have a such high energy density, spiralling costs of their metal inputs have caused some manufacturers to start a race for the most efficient sodium batteries.

Sodium-ion batteries have their own benefits. For one, they are cheaper than other types of cells. They also recharge faster and work well at lower temperatures. And they’re environmentally friendly because they don’t use any rare metals.

The sodium-ion battery has similar working principles to the lithium-ion battery. Sodium ions also shuttle between the cathode and anode. However, compare to lithium ions, sodium ions have a larger volume as well as higher requirements in terms of structural stability and kinetic properties. This has become a bottleneck for the industrialization of sodium-ion batteries.
