The Sodium Solution: Reducing Costs and Complexity in Batteries

Research on sodium-ion batteries aims to reduce reliance on rare elements and cut costs, enhancing battery performance for broader applications. However, fast charging introduces mechanical stresses that compromise the battery’s structural integrity and longevity.

Research is focused on enhancing the performance, longevity, and affordability of new battery materials. Efforts are also being made to decrease the use of scarce and toxic elements like lithium and cobalt. In this context, sodium-ion batteries are emerging as a promising alternative. They operate on principles akin to lithium-ion batteries but are made from raw materials that are readily available in Europe.
