Coupling interconnected MoO 3 /WO 3 nanosheets with a graphene framework as a highly efficient anode for lithium-ion batteries

A rationally assembled three-dimensional graphene framework coupled with interconnected molybdenum/tungsten oxide nanosheets (MoO 3 /WO 3 -GF) has been developed via a one-step template-free strategy. With the unique nanostructure, the obtained anode material not only exhibits a high reversible capacity of about 1000 mA h g −1 , approaching the theoretical capacity of MoO 3 and WO 3 materials, but also shows excellent rate capability and cycling performance with negligible capacity attenuation after a long-time test. These features make it a promising candidate material for high-performance commercial lithium-ion batteries in the future.
