High-quality and ultrathin graphdiyne nanosheets (averaged thickness of 1.9 nm) and nanotubes are first prepared in large-scale using free-standing Cu nanowires as catalyst, forming good 3D continuous network. The crystal boundaries of Cu nanowire are first observed to be highly reactive for catalyzing the growth of graphdiyne nanosheets, giving us some inspirations for preparing more high-quality graphdiyne. Such ultrathin graphdiyne nanosheets show attractive overall performances, and deliver a high capacity of 1380 mAh/g and outstanding rate-performance, thereby exhibiting great potential for high-energy density and highpower density lithium ion batteries.
