Superior Pseudocapacitive Storage of a Novel Ni₃Si₂/NiOOH/Graphene Nanostructure for an All-Solid-State Supercapacitor.

ABSTRACT: Recent developments in the synthesis of graphene-based structures focus on continuous improvement of porous nanostructures, doping of thin films, and mechanisms for the construction of three-dimensional architectures. Herein, we synthesize creeper-like Ni₃Si₂/NiOOH/graphene nanostructures via low-pressure all-solid melting-reconstruction chemical vapor deposition. In a carbon-rich atmosphere, high-energy atoms bombard the Ni and Si surface, and reduce the free energy in the thermodynamic equilibrium of solid Ni-Si particles, considerably catalyzing the growth of Ni-Si nanocrystals. By controlling the carbon source content, a Ni₃Si₂ single crystal with high crystallinity and good homogeneity is stably synthesized. Electrochemical measurements indi
