1. ( 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(xué)碩士學(xué)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(xué)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(xué)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。
