▎ 摘　　要

Unlike activated carbon, graphene sheets are lack of ion pathways on their basal planes and prone to agglomerate or restack unfortunately for their strong pi - pi interactions between neighboring sheets. All of which will pose significant obstacles for its application in high performance supercapacitors. Herein, we report a simple and fast strategy for the scalable synthesis of hierarchical honeycomb-like porous graphene-carbon nanotubes hybrid (PGCTs) through a simple laser induced self-propagating reaction process and subsequent activation with low amount of KOH without any template. Benefiting from properly integration of large surface area, hierarchical pore structures, in-plane nanopores and CNTs nanospacers, the as-obtained PGCTs based symmetrical supercapacitor exhibits outstanding electrochemical performance with super capacitance, excellent rate capability, and desirable cyclability.
