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 hi... 相似文献
