Abstract

Chemical modification of graphdiyne (GDY) can achieve the synthesis of GDY derivatives which also can exhibit excellent electrochemical properties. Here, we demonstrate a unique strategy to drill holes in a GDY carbon skeleton by tailoring the butadiyne linkers. The as-prepared hydrogen-substituted graphyne (HsGY) supplies larger micropore density as well as a large number of C-H bonds, which are key effects for improving the ion migration and enhancing the lithium storage capacity, guaranteeing excellent performance as the anode in lithium ion batteries (LIBs). Notably, the fabricated LIBs deliver a stabilized capacity of 1550 mA h g^-1 at 50 mA g^-1 and long-term cycling stability, implying HsGY can be well utilized in rechargeable batteries.
