( 3 ) the free - standing porous silicon films with continuous porous structure were prepared on single crystal silicon wafer by the method of anodic oxidation and electrochemical etching - electropolishing , and firstly used as the anode materials for lithium ion secondary batteries . the capacities of lithium ions storage and the process of charge and discharge of this nano - silicon anode materials as well as the influence of the structure of ps on behavior of storing lithium ions were inspected at length . on the other hand , through the process of charge and discharge in cells , the lithium of light metal element could be electrochemically doped into ps at different doping levels 胡勁松河北師死大學碩士學位論文( 3 )利用陽極氧化法在單晶硅基底上制備了多孔硅自支撐膜,并首次將這種具有連續(xù)多孔結(jié)構(gòu)的硅材料用作了理離子電池的陽極材料,考察了這種納米級硅陽極的儲鉀性能和充放電過程,分析了材料結(jié)構(gòu)對其儲理行為的影響;另一方面,利用這種電池充放電過程在多孔硅中電化學引入了不同點綴程度的輕金屬鉀元素,考察了鉀點綴對多孔硅自身結(jié)構(gòu),及至性質(zhì)所帶來的影響,提供了一種通過電化學方法插入埋離子從而連續(xù)調(diào)整多孔硅發(fā)光性質(zhì)的有效方法。
