  • α-MoO3 have been prepared into nanosheets full of mesopores on the surface. The effect of mesopores on the nanosheet surface on the electrode performance remains challenging by far. Our obtained MoO3 nanosheets have exhibited great battery performance, including good capacity, elongated recycling life cycles, and excellent rate performance, e.g. above 800 mAh/g when charged under super high current-density of 1000 mA/g. The material demonstrates excellent stability, keeping the capacity of 1189 mAh/g after 20 cycles, and 1075 mAh/g after 50th cycles from decreasing sharply under density of 100 mA/g. The obtained MoO3 nanosheets is of high purity, well-organized, and dense mesopores on the surface, determining the host electrode materials have exhibited good electrode performance, e.g. battery life and capacity and so on. Setting mesopores, or active sites, on the electrode surface should be an alternative way to stable electrode in the furture.

Our obtained MoO3 nanosheets have exhibited great battery performance, including good capacity, elongated recycling life cycles, and excellent rate performance, e.g. above 800 mAh/g when charged under super high current-density of 1000 mA/g. The material demonstrates excellent stability, keeping the capacity of 1189 mAh/g after 20 cycles, and 1075 mAh/g after 50th cycles from decreasing sharply under density of 100 mA/g. The obtained MoO3 nanosheets is of high purity, well-organized, and dense mesopores on the surface, determining the host electrode materials have exhibited good electrode performance, e.g. battery life and capacity and so on.
