  • Beschreibung: AbstractHybrid nanostructures based on graphene and metal oxides hold great potential for use in high‐performance electrode materials for next‐generation lithium‐ion batteries. Herein, a new strategy to fabricate sequentially stacked α‐MnO2/reduced graphene oxide composites driven by surface‐charge‐induced mutual electrostatic interactions is proposed. The resultant composite anode exhibits an excellent reversible charge/discharge capacity as high as 1100 mA h g−1 without any traceable capacity fading, even after 100 cycles, which leads to a high rate capability electrode performance for lithium ion batteries. Thus, the proposed synthetic procedures guarantee a synergistic effect of multidimensional nanoscale media between one (metal oxide nanowire) and two dimensions (graphene sheet) for superior energy‐storage electrodes.
