Self‐Assembled Nanocomposite of Silicon Nanoparticles Encapsulated in Graphene through Electrostatic Attraction for Lithium‐Ion Batteries

An electrostatic attraction directed self-assembly approach for uniform dispersion of Si nanoparticles between two layers of graphene sheets has been developed. The as-obtained Si-NP@G nanocomposite exhibits much improved cycling performance and excellent rate capability.
