| 摘 要： | 应用真空蒸发法在泡沫铜基底上制备锡薄膜负极.XRD、SEM分析表征薄膜的物相结构及其微观形貌,并测试了材料的电化学性能.结果表明,泡沫铜基底的三维结构增强了活性物质与基底的结合力.在同一基底温度下,锡颗粒随蒸发时间延长逐渐增大,电池电化学性能降低;而在同一时间内,升高基底温度,颗粒无明显变化,电池循环寿命有了很大提高.样品A″电池(基底温度:200℃,蒸发时间:0.5 h)经100次充放电循环后比容量仍达407.3 mAh·g-1.

| Abstract: | Sn thin films as the anode materials of Li-ion batteries were prepared by vacuum-evaporation method on the copper foam substrate.The phase structure,surface morphology and electrochemical property of the as-prepared films were characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),and galvanostatic cycling.The results showed that three-dimensional structure of copper foam substrate enhanced the adhesion strength between the active material and the substrate,under the same substrate temper... |
