A nanoflaky MnO2–graphene sheet (GS) hybrid material was mixed with a new binder, sodium alginate, and investigated as a cathode for lithium ion batteries. The MnO2 growing on the GS afforded an unprecedented high capacity of ∼230 mA h g−1 at a large current density of 200 mA g−1, even after more than 150 cycles.
