An Investigation into Sodium-Metal Battery as an Alternative to Lithium-Ion Batteries

M M Nishtha Singh

Abstract: Sodium-ion batteries have attracted the attention of researchers as a more suitable alternative to lithium-ion batteries. However, due to its larger ionic radius compared to lithium-ions, a suitable anode that does not hinder the intercalation process is yet to be found. In this work, I demonstrated that the issue of the large ionic radius of sodium can be avoided with a sodium-metal battery. The maximum potential difference obtained by the sodium-metal battery is comparable to that produced by the current lithium-ion battery, further supporting the possible suitability of sodium-metal battery as an alternative for lithium-ion battery. This allows us to overcome the current global and local concern of lithium-scarcity, encouraging a shift from fossil fuels to renewable energies and help develop technologies.
