N-Vacancy-Functionalized Carbon for High-Rate Li-Ion Storage.

Although heteroatom doping and pore management separately influence the Li adsorption and Li diffusion properties, respectively, merging their functions into a single unit is intriguing and has not been fully investigated. Herein, we have successfully incorporated both heteroatom doping and pore management within the same functional unit of N-vacancy motifs, which is realized via acid etching of formamide-derived Zn-N-functionalized carbon materials (ZnNC). The N-vacancy-rich porous carbon (V-NC) renders multiple merits: (1) a high N content of 13.
