A method is presented for the scalable preparation of high‐quality graphdiyne nanotubes and ultrathin graphdiyne nanosheets (average thickness: ca. 1.9 nm) using Cu nanowires as a catalyst. For the storage of Li + ions, the graphdiyne nanostructures show a high capacity of 1388 mAh g −1 and high rate performance (870 mA h g −1 at 10 A g −1 , and 449.8 mA h g −1 at 20 A g −1 ) with robust stability, demonstrating outstanding overall potential for its applications.
