随着人类生活对储能器件的需求日益强烈,如何高效进行能源转化存储和利用成为重要的技术难题。电极材料是对储能装置的性能影响最大的部分,在碳基材料、导电聚合物、金属氧化物中,金属氧化物由于具有高比电容、高能量密度而备受关注。但研究发现单一的金属氧化物电极材料的电化学性能并不十分优异,研究者们常常对金属氧化物进行改性来提升其储能性质。鉴于此,主要针对构建复合电极材料、多元电极材料、杂化金属氧化物等常用的金属氧化物改性研究进展进行总结,旨在为设计优异电化学储能性能的金属氧化物电极材料提供方向。
With the increasing demand for energy storage devices in human life,how to efficiently convert,store and utilize energy become an important technical problem.The electrode material is the most important part and has the greatest impact for the energy storage device.Among carbon-based materials,conductive polymers,and metal oxides,metal oxides have attracted much attention due to their high specific capacitance and high energy density.However,it is found that the electrochemical performance of the single metal oxide electrode material is not satisfactory.The metal oxides electrode material is usually modified by researchers to improve energy storage performance.Therefore,the commonly used metal oxide modification methods such as composite electrode materials,multi-element electrode materials and hybrid metal oxides were mainly summarized,aiming to provide directions for designing metal oxide electrode materials with excellent electrochemical energy storage performance.
