In‐Plane Vacancy‐Enabled High‐Power Si–Graphene Composite Electrode for Lithium‐Ion Batteries

Abstract

Introducing a high density of in-plane, nanometer-sized carbon vacancies in graphene sheets greatly enhances ion diffusion across the sheets in a Si–graphene composite. The flexible, self-supporting three-dimensional conducting graphenic scaffold incorporating Si nanoparticles exhibit excellent rate performance and tolerance to structural deformation, which represents an attractive high power-high capacity anode material for Li-ion batteries.
