With the accelerated consumption of fossil fuels and the increasing energy crisis,supercapacitors,as new energy storage components,have attracted great attention from researchers. In this paper,biomass-based porous carbon was prepared by hydrothermal method,and the microstructure and elemental composition of the material were analyzed. The electrochemical properties of the electrode as a supercapacitor electrode material were studied. The results show that the specific capacity of the biomassbased tamarindus indica-derived porous carbon material increased from 166 F · g-1 to 232 F · g-1,indicating that doping can effectively improve the capacitance performance of biomass-derived porous carbon materials.WU Hao,ZHU Zi-yi,XIAO Jie,ZHANG Ying-jie,DONG Peng,ZENG Xiao-yuan( Key Laboratory of Advanced Battery Materials of Yunnan Province,National and Local Joint Engineering Laboratory for Lithium-ion Batteries and Materials Preparation Technology,Faculty of Materials Science and Engineering,Kunming University of Science and Technology,Kunming 650093,China)bstract: With the accelerated consumption of fossil fuels and the increasing energy crisis,upercapacitors,as new energy storage components,have attracted great attention from researchers.
