ABSTRACT
Transition metal (TM) oxides owing to their high theoretical capacities are considered promising candidates for electrode materials in lithium ion batteries (LIB) and sodium ion batteries (NIB). They have contributed to the overall improvement in the electrochemical performance, operating voltage, cycling ability, and thermal stability (and overall safety). Layered transition metal oxides have, over the years, shown they are excellent electrode materials via a display of high specific capacity, environmental benignity, and ease of fabrication/synthesis. Through incorporation of TM in the structure, researchers have tried to address the issues that are prevailing in the domain of secondary batteries viz. irreversible phase transition, storage ability, battery performance etc. This chapter deals with the latest advancement in the TM-oxide-based LIBs and NIBs, their structural stability, and cyclic performance and will be understood in terms of a TM ion substation in binary, ternary transition metal oxide form.
