Carbon materials have become one of the most important materials for electrochemical energy storage devices due to their advantages, such as low price, easy preparation, environmental friendliness, high electrical conductivity and large specific surface area, in addition, they are suitable for ion storage and migration. Graphdiyne (GDY), as a new two-dimensional carbon allotrope, is composed of benzene ring in sp(2) carbon hybridization form and acetylene bond in sp carbon hybridization form. This unique chemical structure, on the one hand, keeps the good conductivity of carbon materials, and on the other hand, forms a novel ion transport channel, which endows the carbon materials with different ion transport and storage characteristics. At the same time, on account of the adjustable spatial structure of graphdiyne, the electronic structure of graphdiyne can be fine-tuned through the introduction of hetematoms, which greatly expands the application range of graphdiyne in the field of electrode materials. In this paper, the recent years' work on heteroatomic graphdiyne electrode materials used in lithium ion battery, sodium ion battery, metal sulfur battery, capacitor, metal air battery, electrode protection and other energy storage fields is summarized, and the future development direction of graphdiyne electrode materials applied to the energy storage field is prospected. |
