Abstract: In this work,activated carbon with a hierarchical porous structure was prepared by hydrothermal and activation treatment with the medicinal residue of Sargentodoxa cunea as raw material,and its electrochemical properties as cathode material for zinc-ion hybrid supercapacitor were studied. Studies have shown that the activated carbon prepared at an activation temperature of 800 ℃ has a specific surface area of 2516 m~2/g and a total pore volume of 1.335 cm~3/g. The specific capacity of the hybrid supercapacitor is as high as177.1 mAh/g at a current density of 0.1 A/g,which is much better than that of the traditional supercapacitor;at a current density of 10 A/g,the specific capacity can still be maintained above 74.6 mAh/g,after 4000 charge-discharge cycles at a current density of 1.5 A/g,the capacity retention can reach 85%,showing good rate capability and charge-discharge cycling stability. The abundant network of micropores,mesopores and macropores,as well as ion size matching between micropores of activated carbon and electrolyte ions,are the keys to ensure high-efficiency ion storage.
