在所有的电化学超级电容器电极材料中,研究最早和技术最成熟的是碳材料。其

Among all electrochemical supercapacitor electrode materials, carbon materials are the earliest research and most mature technology. Its research started from related patents published by Beck in 1957. In its development, porous carbon materials, activated carbon materials, activated carbon fibers [86,87], carbon aerogels [102,103], and carbon nanotubes [104] have appeared. From the perspective of the development trend of materials, it is mainly based on the principle of electric double layer energy storage, towards the direction of electrode materials with high specific surface area, reasonable pore size distribution and small internal resistance.
