Three-dimensional printing of graphene-based materials and the application in energy storage

Abstract

Graphene-based materials have been extensively investigated in the energy-related applications owing to their unique properties, such as high conductivity and mechanical flexibility. Three-dimensional (3D) graphene architectures could further strengthen their performance and facilitate the applications in energy storage. To fabricate 3D graphene architectures, the rapidly developed 3D printing technology presents a lot of advantages and has received much research attention. In this paper, we reviewed the recent research advances of 3D printing of graphene-based materials and discussed the applications in energy storage areas. The main 3D printing techniques applied in constructing graphene-based structures were summarized, and the characteristics of each method were briefly introduced. The current progresses of energy storage applications, focusing on supercapacitors and energy storage batteries, were reviewed in detail. Moreover, the future research challenges and prospects were provided in the last part, aiming at stimulating more significant research and industrial applications in this subject.
