Abstract: Afacile and green freeze-drying-assisted method was proposed to synthesize mesoporous NiMoO4 nanoclusters. The mesoporous NiMoO4 nanoclusters exhibit high specific capacity and good rate performance when evaluated as anode materials for lithium-ion batteries (LIBs). The reversible specific capacity can be kept at 1 104.8 mAh/g after 100 cycles at a current density of 0.2 A/g, about 0.09% capacity fading per cycle. Even at the current densities of 1 A/g and 2 A/g, the mesoporous NiMoO4 nanoclusters electrode can still retain the reversible capacities of 664.7 mAh/g and 468.4 mAh/g, respectively. Furthermore, the full cell(mesoporous NiMoO4 nanoclusters anode/LiFePO4 cathode) displays a stable discharge capacity of 152.1 mAh/g at 0.1 C(1 C=170 mA/g). The improved electrochemical performance of mesoporous NiMoO4 nanoclusters is closely related to their unique porous structures and shorter diffusion pathways of lithium ions. This work offers a new perspective to the design of other porous electrode materials with a good energy storage performance.
