Perspective to the Potential Use of Graphene in Li‐Ion Battery and Supercapacitor

Graphene is a hot star in materials science with various potential application aspects, including in Li‐ion battery and supercapacitor. The burst of scientific papers in this area seems to validate the performance of graphene, but also arouses large dispute. Herein, we share our judgment of these trends to all, encouraging the discussion and enhancing the understanding of the structure‐performance relationship of graphene. Graphene exhibited high surface area, exohedral pore structure, high chemical stability and excellent electrical conductivity and was promising for the potential use of supercapacitor or Li‐ion battery. The present work mainly discuss the technical challenges toward commercialization.
