High-capacity Vanadium Nitride Anode Materials by Melamine-assisted Pyrolysis

Structurally controllable clustered shuttle metal-organic frameworks (V-MOF) are selected as precursors, and melamine (C 3 H 6 N 6 ) derived carbon is encapsulated on the surface of the V-MOFs by using high-temperature pyrolysis, resulting in the formation of N, C-codoped VN electrode materials (VNNC).
