Sodium-ion batteries can be significantly cheaper than lithium-ion ones since sodium is much more abundant than lithium, and they do not use the expensive cobalt.
Electric vehicles are becoming increasingly popular the world over, as consumers want vehicles with little to no emissions and governments promote such vehicles to meet their own net-zero emission goals. But the cost of EVs, when compared to internal combustion engine vehicles, has been a major resistance factor for a more distributed adoption.
One of the major factors behind the higher costs of EVs are their lithium-ion (Li-ion) batteries. Some estimates suggest that lithium-ion batteries, which make up the majority of all batteries across all sorts of electronic devices, contribute to 20-40 percent of EVs’ costs.

What is the alternative?
While automobile manufacturers, battery makers, and various startups in the ecosystem are working on developing alternatives to lithium-ion batteries, few options already exist. One of the most promising alternatives is the use of sodium-ion (Na-ion) batteries over lithium-ion batteries. Na-ion batteries have several advantages over the traditional Li-ion batteries in a variety of end-uses.
Lithium and sodium are both alkali metals, and are right next to each other on the periodic table. Sodium and Lithium consequently share a lot of similarities.
