Ultrathin Graphdiyne Nanosheets Grown In Situ on Copper Nanowires and Their Performance as Lithium‐Ion Battery Anodes

Abstract

AbstractA 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.
