锰氧化物的合成及在锂离子电池中的应用进展

Energy is an important factor limiting human being's development. In recent years, people have higher and higher requirements for energy storage equipment with the development of new energies. Among them, lithium-ion battery (LIB) is considered to be one of the most promising energy storage devices. At present, graphite is the main anode material for commercial LIBs. Although graphite has good electrical conductivity, its theoretical capacity is low. Thus, graphite has gradually been unable to meet the demands for large capacities of high-energy equipment. Transition metal manganese oxides are considered as one of the ideal anode materials for LIBs due to their sufficient reserve, diverse oxidation states, diversified structures, high theoretical specific capacities and environmentally friendly. In this paper, the design and synthesis of four kinds of manganese oxides (MnO, Mn₂O₃, Mn₃O₄ and MnO₂) through nano-crystallization and constructing composite structures were introduced. Moreover, the performance of four kinds of manganese oxides used as anode materials for LIBs was summarized and compared. The development prospects and future trends of manganese oxide in the anode material fields in LIBs were also prospected.
