摘要
目前基于石墨烯复合电极材料的超级电容器(简称石墨烯超级电容器)显示出了传统电容器无可比拟的优势:传统电容器不具备大容量储能特点,能量密度较低;石墨烯超级电容器具有良好的电容特性和循环稳定性,具有较高的功率密度和较长的循环寿命,可用于大量储能。近些年国内外有大量人员尝试出制备各种性能优异的石墨烯超级电容器,有较强的工业化前景。对石墨烯超级电容器的制备方法的最新进展进行综述,并对其前景进行展望。
At present, supercapacitors based on graphene composite electrode materials(hereinafter referred to as graphene supercapacitors) show the incomparable advantages of traditional capacitors: Traditional capacitors do not have the characteristics of large capacity energy storage, Low energy density; Graphene supercapacitor has good capacitance characteristics and cycle stability, It has higher power density and longer cycle life, and can be used for large energy storage. In recent years, a large number of people at home and abroad have tried to prepare graphene supercapacitors with various properties, which has a strong prospect of industrialization.Therefore, we will summarize the recent progress in the preparation methods of graphene supercapacitors in this article, And its prospect is prospected.
