摘　　要：将ZnO浸泡在镁和钙的醋酸盐溶液中 ,通过蒸发、高温等处理得到了表面改性的ZnO样品。采用XRD、SEM对其结构和形貌进行了表征 ,同时用恒电流充放电等技术研究了其充放电特性和循环稳定性。实验结果表明 :通过对氧化锌进行表面改性处理 ,改进了其电化学性能 。ZnO was suface-modified with oxide by immersed in Mg(CH-3COO)-2 or Ca(CH-3COO)-2 solution, then evaporated and subsequent heated at high temperature. The crystal structure was characterized by XRD and SEM. The charge/discharge behavior and cycle lifetime were tested by Galvanostatic charge-discharge experiment. The experimental results showed that zinc oxide surface-modified by MgO or CaO has better electrochemical performance and longer cycle time than pure ZnO.
