Abstract:

A facile hydrothermal route has been developed to prepare MnO2/graphene nanocomposites and MnO2 nanoparticles are uniformly anchored on graphene nanosheets. The composite were studied as the anode material for lithium-ion batteries. The surface of graphene is modified by MnO2 nanoparticles which are 10-30 nm in size and homogeneously anchor on graphene sheets. The composite exhibits superior lithium battery performance with higher reversible capacity and better cycling performance. The reversible capacity is up to 781.5 mAh g-1 at a current of 100 mA g-1 and maintains 96% after 50 cycles. The enhanced lithium storage performance is due to the synergetic effect of graphene and MnO2.
