Abstract:

Bamboo shoots were used as raw material to carbonize to obtain biomass charcoal,and then activated with KOH to obtain porous biomass charcoal.The microstructure and morphology of porous biomass charcoal were characterized by scanning electron microscope(SEM),transmission electron microscope(TEM),X-ray diffraction(XRD) and physical adsorption of nitrogen,etc.By using this porous biomass carbon as a anode material to explore its electrochemical performance,the results showed that at a current density of 1 000 mA/g,the first?round charging specific capacity was 286.9 mA·h/g,and after 50 cycles,the charging specific capacity remained at 201.8 mA·h/g.After 500 cycles,the charging specific capacity was still 221.5 mA·h/g,indicating that the porous carbon material had excellent electrochemical cycling performance,making it a promising anode material for lithium batteries.

Key words: biomass material, porous carbon, anode material, lithium ion battery
