Printing Assembly and Structural Regulation of Graphene towards Three-dimensional Flexible Micro-Supercapacitors

Abstract

Flexible, miniature, and high-performance supercapacitors that offer reliable energy storage and output are needed for portable and wearable electronics. Here we develop micro- supercapacitors with three-dimensional electrodes by printing assembly of graphene. By controlling the microstructures and macroscopic architectures of the graphene electrodes, superior electrochemical performances are achieved, especially making breakthrough for the limitation of areal capacitance. The unique three-dimensional graphene structure also provides this new class of micro-supercapacitors with exceptionally mechanical flexibility. With these remarkable features, facile integration of the micro-supercapacitors array with flexible printed circuits is demonstrated. The printing assembly approach will pave the way to explore energy storage systems with diverse structures and extended properties.
