Here, a new approach to further improve graphdiyne (GDY) based materials by using benzyl disulfide (BDS) as the sulfur source is demonstrated. The S radicals, generated from the homolysis of BDS, can react with the acetylenic bonds and be well confined in the triangle‐like pores of GDY, forming S‐GDY. The as‐prepared S‐GDY, which possesses numerous heteroatom defects and active sites, is suitable for applications in many electronic devices, such as lithium ion batteries (LIBs). As expected, the assembled LIBs based on S‐GDY displayed improved electrochemical properties, including larger capacity and superior rate capability.
