Abstract

Abstract: A facile, low‐cost, and efficient electrochemical exfoliation method is demonstrated to prepare three‐dimensional nitrogen‐doped graphene frameworks on a large scale. Benefiting from the enhanced specific surface area, increased conductivity and enriched active sites, the nitrogen‐doped graphene framework electrode exhibits remarkable capacitance, good cyclic stability, and superior rate capability (65.3% capacitance retention), outperforming most of the reported graphene‐based electrodes.
