Graphene‐Wrapped MnO₂–Graphene Nanoribbons as Anode Materials for High‐Performance Lithium Ion Batteries

Abstract

A facile and cost-effective approach for the fabrication of a hierarchical nanocomposite material of graphene-wrapped MnO2 -graphene nanoribbons (GMG) is developed. The resulting composite has a high specific capacity and an excellent cycling stability owing to the synergistic combination of the electrically conductive graphene, graphene nanoribbons, and MnO2 .
