High Performance Graphene/Ni2P Hybrid Anodes for Lithium and Sodium Storage through 3D Yolk–Shell‐Like Nanostructural Design

A 3D yolk–shell-like electrode material composed of a porous interconnected graphene network and embedded Ni2P nanoparticles is designed and fabricated by an assembly and self-template strategy. This novel nanoarchitecture integrates the advantages of nanostructure and microstructure, and provides highly efficient and stable electrochemical circuits involving the active nanoparticles, leading to excellent electrochemical performance in terms of reversibility, rate capability, and cycle stability.
