The porous carbon material prepared from naturally abundant bamboo shoot shell for the application of supercapacitor is put forward. It not only makes waste biomass to be profitable, but also provides a sustainable development way for the preparation of the new porous carbon material. The physicochemical and electrochemical properties of the as-prepared porous carbon samples are studied in detail. The results show that the porous carbon sample prepared at 5:1 weight ratio of KOH to bamboo shoot shell derived carbon (BSSDC) exhibits a specific surface area of ~ 3408 m2 g-1 (BSSDAC-5). In addition, the BSSDAC-5 shows a high specific capacitance of 308 F g-1 at 1 A g-1 and high capacitance retention of 97.40% even after 10000 cycles, indicating its potential application for high-performance supercapacitors.
