A promising anode material for sodium-ion battery with high capacity and high diffusion ability: graphyne and graphdiyne
January 2016 • Zhenming Xu, Xiaojun Lv, Jie Li, Jiangan Chen, Qingsheng Liu
First-principles calculations indicate that a novel atomic hollow structure of graphyne and graphdiyne made up of sp- and sp<sup>2</sup>-hybridized carbon atoms reinforces not only the Na storage capacity but also the Na diffusion.
