摘　　要：利用磁控溅射薄膜沉积技术设计制备了具有纳米阵列结构的3种(Cu O、Cu4O3、Cu2O)铜氧化物薄膜,将其直接用作锂电池负极材料进行电化学性质的表征测量.经循环200次之后,结果发现Cu O负极薄膜虽然在前50次经历了容量衰减,但之后保持有最高的比容量.在此基础上,将Cu O负极薄膜与商业钴酸锂正极匹配制作出软包薄膜全电池,并对其性能进行了表征测试,为设计高容量全电池薄膜负极材料提供一个可行的方案.Three kinds of copper oxide( CuO,Cu4O3,Cu2O) thin films with nano-array structure were prepared by magnetron sputtering. They were used as anode materials for thin film Liion battery. We found that although the CuO thin film anode suffered from the capacity deceasing during the first 50 th cycles,it could maintained the highest capacity until 200 cycling. On this basis,we selected CuO film as the anode and LCO as the cathode material for designing the full battery by lamination process and conducted characterization on the full battery performances. This work may provide a feasible solution for designing high-capacity thin film anode.
