Nanosheets with mesopores on the surface have been prepared using molybdenum trioxide (α-MoO3).The effect of mesopores on the performance of the electrode remains elusive.The MoO3 nanosheets obtained in this study exhibited great battery performance,including good capacity,prolonged recycling life cycles,and excellent rate performance; e.g.,780 mAh/g when charged under a super high current-dens-ity of 1000 mA/g.These nanosheets demonstrated excellent stability,maintaining a capacity of 1189 mAh/g after 20 cycles,and 1075 mAh/g after 50 cycles; thus preventing the capacity to decrease to values under the scanning rate of 100 mA/g.These high-purity MoO3 nanosheets are well-ordered and have dense mesopores on the surface; these micropores contribute to the excellent electrode performance of the host elec-trode materials; the performance parameters include prolonged battery life and capacity.Setting mesopores or active sites on the electrode sur-face can be an alternative way to obtain stable electrodes in the future.
