Ultrafastly activated needle coke as electrode material for supercapacitors
文献摘要：
The uniform porous structure makes activated porous carbons(APCs)superior electrode material.Traditionally,APCs are produced by a combination of time-consuming high-temperature heat treatment and activation,with a production time of up to several hours.The produced APCs have relatively low specific surface area(SSA)and porosity.Therefore,the electrochemical performance is poor,which limits its application in high-power energy storage devices.Here,APCs materials are directly synthesized by a high temperature shock(HTS)strategy using needle coke as a precursor.The structure of as-prepared APC is characterized by XRD,SEM and Raman,and electrochemical tests confirmed its good electrochemical performance.In the two-electrode system,the super-capacitor with HTS-APC as the electrode material provides a high energy density of 35 Wh kg-1 and a high power density of 875 W kg-1 in EMIMBF4 ionic liquid.This work is instructive for the rapid synthesis of electrode materials,and also provides guidance for the large-scale application of porous carbon materials.
