摘要
能源是限制人类发展的重要因素,近年来随着新能源的发展,人们对于储能设备的要求也越来越高,其中,锂离子电池被认为是最具有发展前途的储能设备之一。目前,商用锂离子电池的负极材料以石墨为主,石墨虽然具有良好的导电性,但理论容量较低,已逐渐无法满足高能设备的大容量需求。过渡金属锰氧化物由于储量丰富、氧化形态多样、结构多元、理论比容量高、环境友好等特点,被认为是锂离子电池理想的替代负极材料之一。本文详细介绍了近年来4种锰氧化物(MnO、Mn_(2)O_(3)、Mn_(3)O_(4)和MnO_(2))分别在纳米化和复合结构构筑两方面的材料设计及合成,总结比较了4种锰氧化物用作锂离子电池负极材料的性能,展望了锰氧化物在锂离子电池负极材料领域的发展前景和方向。
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,Mn_(2)O_(3),Mn_(3)O_(4) and MnO_(2))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.
