3D Fe2(MoO4)3 microspheres with nanosheet constituents as high-capacity anode materials for lithium-ion batteries

Three-dimensional (3D) Fe-2(MoO4)(3) microspheres with ultrathin nanosheet constituents are first synthesized as anode materials for the lithium-ion battery. It is interesting that the single-crystalline nanosheets allow rapid electron/ion transport on the inside, and the high porosity ensures fast diffusion of liquid electrolyte in energy storage applications. The electrochemical properties of Fe-2(MoO4)(3) as anode demonstrates that 3D Fe-2(MoO4)(3) microspheres deliver an initial capacity of 1855 mAh/g at a current density of 100 mA/g. Particularly, when the current density is increased to 800 mA/g, the reversible capacity of Fe-2(MoO4)(3) anode still arrived at 456 mAh/g over 50 cycles. The large and reversible capacities and stable charge-discharge cycling performance indicate that Fe-2(MoO4)(3) is a promising anode material for lithium battery applications.
