ABSTRACT
Porous carbon aerogel, as an ideal material for supercapacitors, has been widely researched by researchers because of its high electron conductivity, high specific surface area, abundant micropores, and wide range of raw materials. However, with an in-depth study of porous electrode materials, it is found that the classical electric double-layer theory in porous electrode materials deviates greatly from the actual experimental results. In this regard, this chapter will focus on the charge storage mechanism of porous carbon materials and the relationship between porous carbon materials and capacitance. More importantly, carbon aerogel has been the emerging carbon material in the 21st century, and this chapter focuses on the preparation method of carbon aerogel and its application in supercapacitors.
