Directional Design of Fast-Conductivity and Porous Zn-based Anodic Materials for Zinc-Nickel Alkaline Batteries

Dendrites, passivation, and other adverse reactions impede ZnO from being a high-density anode in alkaline zinc-nickel batteries. With heat treatment and precipitation methods, ZnO nanosheets were uniformly grown on the surface of nitrogen-doped porous carbon (NPC), the composites named ZnO@NPC. ZnO@NPC, a new composite as the anode material of zinc-nickel batteries, was inspected for excellent cycle performance during the charge and discharge process at a high rate (8 C), and the capacity retention with a discharge specific capacity of 570.6 mAh g−1 is 97.54
