【摘要】 本文采用真空蒸发制备了V2O5薄膜，用电化学方法从Li离子电解质中向V2O5薄膜注入Li离子.研究了V2O5薄膜中Li离于储存特性、注入／退出可逆性以及电荷注入对其光学性能的影响．实验结果表明，V2O5薄膜具有较好的Li离子储存特性和注入／退出可逆性，Li离子的注入量受到膜中V5+的含量以及锂离子可占据的总位置数限制，而且离子注入后V2O5薄膜的光学性能变化较小．更多还原

【Abstract】 Lithium was inserted electrochemically from an electrolyte into V2O5 thin films prepared by evaporation and posttreated at different temperatures in air so that LixV2O5 was obtained. Li+storage properties, reversibiliy of Li+ intercalation/deintercalation in V2O5 thin films and influence of Li+ insertion on their optical properties were investigated. The experimental results show that two factors, the V5+ concentration and the sum total of sites in V2O5 thin films, control the capacity of Li+ insertion into V2O5 thin films, and that these thin films have a good Li+ storage characteristic, stability and reversibility.更多还原
