Abstract A new carbon allotrope, graphdiyne (GDY) has great promise for future use. Much interest was piqued when it was initially prepared in 2010. GDY is made up of sp‐ and sp 2 ‐hybridized carbon atoms. It has a one‐atom thick two‐dimensional structure and many interesting and useful qualities, such as strong chemical bonds, super‐large π structures, the ability to change from an alkyne to an alkene, and can be grown on any surface. GDY has become one of the frontier hotspots in chemistry and materials science, with original research achievements in energy conversion and storage, catalysis, intelligent information, life sciences constantly emerging and so on, showing revolutionary performance. In electrochemical cells, the electrode interface content not only accounts for a small proportion in the entire electrode system but it also plays a crucial role, affecting the efficiency, lifespan, power performance, and safety performance of the battery. In view of this, the intrinsic properties of GDY have been thoroughly analyzed, and a new GDY‐based electrochemical interface has been proposed by combining the key problems of electrochemical interfaces in electrochemical energy storage and conversion. This has led to new understanding and insights to address many critical scientific issues. In this review, the structure, characteristics, and applications of GDY in interface engineering are presented. In particular, recent advances in GDY and its aggregates in energy storage and conversion are summarized and discussed.
