Vertically Oriented Graphene Bridging Active‐Layer/Current‐Collector Interface for Ultrahigh Rate Supercapacitors

Dense networks of graphene nanosheets standing vertically on a current collector can work as numerous electrically conductive bridges to facilitate charge transport and mitigate the constriction/spreading resistance at the interface between the active material and the current collector. The vertically oriented graphene-bridged supercapacitors present excellent rate and power capabilities.
