Simultaneous Formation of Ultrahigh Surface Area and Three‐Dimensional Hierarchical Porous Graphene‐Like Networks for Fast and Highly Stable Supercapacitors

Abstract

A new one-step ion-exchange/activation combination method using a metal-ion exchanged resin as a carbon precursor is used to prepare a ultrahigh surface area and three-dimensional hierarchical porous graphene-like networks for fast and highly stable supercapacitors.
