近年来,二维石墨烯和准二维无机类石墨烯材料作为电极材料广泛应用于超级电容器,随着便携式电子器件的快速发展,超薄、柔性储能器件的研发必不可少.其中,具有柔性乃至平面构型的超薄超级电容器正在迅速兴起,成为一种极具潜力及发展优势的能量存储器件,而二维材料在该类器件的构建中至关重要.本文概述了全固态柔性超级电容的构建原理,特别是二维/准二维材料在构建柔性超级电容器中的材料选择与复合提高性能,综述了平面超级电容器的发展,展望了下一代平面超级电容器在柔性能源存储器件中可能的应用前景.

Two-dimensional （2D） graphene/quasi-two-dimensional inorganic materials have been widely explored for construction of energy- related applications. Catering for rapid development of portable electronic devices, energy storage devices with ultra-thin and high flexibility are urgently needed. Very recently, planar supercapacitor with novel configurations has been rapidly developed as important energy storage devices. In this regard, the assembled thin film of 2D graphene and quasi-2D graphene analogues acted as the vital role for the planar configurations as well as the enhanced performances in the construction of planar energy storage device. This review summarized the construction concept of flexible supercapacitors in all-solid-state based on 2D graphene and quasi-2D graphene analogues. We also surveyed how to select quasi-2D graphene analogues with high electrochemical properties, and even how to use the synergic advantages of hybrid structure for further performance enhancement of planar supercapacitors. Recent progresses and possible future applications on planar supercapacitors were also reviewed and outlooked.
