Abstract: | Sodium-ion batteries are becoming potential solutions for replacement of batteries due to the abundance of sodium reserves and high recycling costs of lithium-based batteries. Sodium-based layered oxides are being widely explored as positive electrode material for sodium-ion battery due to their high capacities and high energy densities. However, oxide-based systems do suffer from thermal stability issues and exhibit low power density. On the other hand, polyanionic-based compounds and Prussian blue analogues demonstrate appreciable thermal stabilities and are useful in high power density applications. This article reviews recent trends of these cathode materials. |
