Abstract:
Sodium-ion batteries are a hot topic in the modern scientific world. Because of the rapid depletion of Lithium resources, a replacement for the Lithium-ion batteries should be a great investment in future world. Considering the similar rock and chair mechanism with the Lithium, one can expect that inexpensive Sodium will be a potential candidate for a replacement. Even though number of cathode materials that were accommodated in Lithium-ion batteries was also tested with Sodium-ion batteries, a similar performance was not achieved with each and every material. Sodium-ion battery development field is relatively young in Sri Lanka. However, considering the sodium supply and mineral resources in Sri Lanka, one can expect it to have a great potential for further advancements within the country. In here we review the work previously done on Oxide, Silicate and Phosphate based transition metal compounds as cathode materials for the Sodium-ion batteries in Sri Lanka. It further discusses the performance and drawbacks when they are accommodated as cathode materials for sodium-ion batteries.
