Sodium-ion batteries (NIBs) are attractive alternatives to lithium-ion batteries (LIBs) due to the relative abundance of sodium compared to that of lithium resources. The working principle of a sodium-ion battery is very similar to that of a lithium-ion battery, which is based on shuttling of the ions between the positive and the negative electrode through the electrolyte. Commonly applied negative electrode materials for NIBs are hard of soft carbons, which is mainly due to the thermodynamic instability of Na+ intercalation to graphite. Sodium-containing compounds serve as the positive electrodes, such as Prussian white. Both electrodes use aluminum as the current collector, so aluminum corrosion must be considered while selecting the suitable salt/solvent/additive combination for the electrolyte.

Application fields

The gravimetric energy density of NIBs (70-150 Wh kg-1) is typically lower than that of commercial LIBs (160-260 Wh kg-1), Depending on the used chemistry, Na-ion are suitable to be applied for smaller-scale energy storage applications with an improved safety.
