Lithium ion battery (LIB) is the most promising energy storage device in the fields of electric vehicles (EVs) and hybrid electric vehicles (HEVs) for its high voltage, high energy density and long life. In order to develop high-performance LIBs for EVs and HEVs, it is essentially to develop electrodes with high rate capability. Novel nanostructures of metal oxides have attracted much attention as improved anode materials because of their high capacities and possible high rate capability, which were attributed to their large specific surface area and the short electronic and ionic transport length in nanoscale.
Among all the transition metal oxide, manganese oxide material (MnO and MnO2) stand out from the crowd. This is not only because of the high capacity (MnO: 755 mAh/g, MnO2: 1230 mAh/g, theoretical), non-toxicity and environmental friendliness, but also because of the lower charge-discharge potential, which is known to be the lowest charge and discharge potential in transition metal oxide materials. This paper mainly focuses on preparing manganese oxide electrode with superior lithium storage properties by specific and novel morphology and electrode structure.
