过渡金属硫化物在超级电容器研究进展

s a new type of energy storage device, supercapacitor has the advantages of high power density, fast charging speed, long cycle life and environmental friendliness. Essentially, the electrode materials used in supercapacitors directly determine the electrochemical performance of supercapacitors to a large extent, therefore, choosing the appropriate electrode materials is very important for supercapacitors. Transition metal sulfides have high electrical conductivity, superior electrochemical activity and diversity of stoichiometric points and are widely used in supercapacitors. This article reviews the application of several transition metal sulfides in supercapacitors, and selects several for a brief introduction.
