There is a promising alternative to conventional lithium-ion batteries, namely sodium-ion batteries. In these batteries, it is sodium ions instead of lithium ions that flow back and forth between the electrodes and in this way, store or release electrical energy.
Sodium-based batteries have a major advantage: unlike lithium, which is comparatively rare, sodium is available on earth in practically unlimited quantities. As a natural component of salt, it can be extracted from salt lakes or mines. ...
