Graphdiyne-Based Materials: Preparation and Application for Electrochemical Energy Storage

摘要

Graphdiyne (GDY) has drawn much attention for its 2D chemical structure, extraordinary intrinsic properties, and wide application potential in a variety of research fields. In particular, some structural features and basic physical properties including expanded in-plane pores, regular nanostructuring, and good transporting properties make GDY a promising candidate for an electrode material in energy-storage devices, including batteries and supercapacitors. The chemical structure, synthetic strategy, basic chemical-physical properties of GDY, and related theoretical analysis on its energy-storage mechanism are summarized here. Moreover, through a view of the mutual promotion between the structure modification of GDY and the corresponding electrochemical performance improvement, research progress on the application of GDY for electrochemical energy storage is systematically explored and discussed. Furthermore, the development trends of GDY in energy-storage devices are also comprehensively assessed. GDY-based materials represent a bright future in the field of electrochemical energy storage.
