Mn-based oxides have gained gigantic attention due to its high theoretical capacities, low charge discharge potential vs Li/Li+, high abundance and low price. However, poor-capacity retention and rate capability due to large volume variation during cycling are serious issues with Mn-based oxides. So it is necessary to develop a material which accommodate the aforesaid volume variation that prevents pulverization of active material and thereby high capacity retention may be anticipated. Further, importance of matrix element for high performance LIB anode will also be discussed. The choice of electroactive element (responsible for alloying/dealloying reaction) comprising of high mechanical strength, high wear resistance and good ductility is found to be beneficial becuase both the elements (alloying as well as conversion) provide ionic/electronic conducting channels inside oxides frame work through which the participation of active material present in electrode increases significantly and thereby high capacity may be realized.
