摘　　要：超级电容器作为一种新型的电能存储器件因具有快速充放电、循环寿命长和环境友好等优点,具有广阔的应用前景。超级电容器主要由电极材料、隔膜、集流体、电解液以及外部的封装材料组成。其中,电极材料是超级电容器的核心部分,是影响超级电容器性能的关键因素。以结构为依据可将电极材料分为晶态与非晶态两大类。相比于晶态电极材料,非晶态电极材料由于其原子排布无序,具有较高的理论比容量、优异的循环稳定性和较高的充放电速率,从而被广泛应用于超级电容器。本文综述了非晶过渡金属化合物电极材料(氢氧化物、氧化物、硫化物以及硒化物)的合成以及其对应的电化学性能,并对非晶态电极材料的未来研究趋势进行了展望。As a new type of energy storage device,supercapacitor has broad application prospects due to its advantages of fast charge and discharge,long cycle life and environmental friendliness.Supercapacitors are mainly composed of electrode materials,separators,current collectors,electrolytes and external packaging materials.Among them,the electrode material is the core part of the supercapacitor and is a key factor affecting the performance of the supercapacitor.Based on the structure,electrode materials can be divided into two categories:crystalline and amorphous.Compared with crystalline electrode materials,amorphous electrode materials are widely used in supercapacitors due to their disordered atomic arrangement,high theoretical specific capacity,excellent cycle stability and high charge-discharge rate.In this paper,the syntheses of amorphous transition metal compounds electrode materials(hydroxides,oxides,sulfides and selenides)and their corresponding and electrochemical properties are reviewed,and the future research trends of amorphous electrode materials are prospected.
