Abstract: Lithium-ion batteries (LIBs) are recently being considered for use in electric vehicles. However, energy density, power density and safety of LIBs still need considerable improvement. On the other hand, sodium ion batteries (NIBs) are thought to be promising for large scale renewable energy storage systems owing to their lower cost. Nevertheless, NIBs are still at their nascent stage and appropriate electrode materials have not been comprehensively identified. Hence, technological advancements in both LIBs and NIBs are necessary. To improve the energy density in LIBs, high capacity anode materials that deliver ~2-3 times higher capacity than graphite anodes have been developed. In addition, high power density batteries have been developed using nanostructured lithium titanate. On the sodium-ion battery front, new anode materials have been identified. Surprisingly, transition metal oxides investigated for lithium storage by conversion reaction also show promising sodium storage properties.
