dc.description.abstract应用高温热解法合成层状二氧化锰(δ-MnO2),借助离子注入技术在其表层注入钛离子,形成复合材料(δ-MnO2-Ti).材料结构及形貌由XRD、SEM及XPS表征,用恒电流充电仪测定其电化学性能.结果表明:注入钛离子后形成新的复合材料,其MnO2的层状结构没有被破坏,钛离子主要以Ti(Ⅳ)态嵌入MnO2结构.与δ-MnO2相比,改性后的δ-MnO2-Ti首次放电比容量和最大放电比容量均有明显提升.zh_CN
dc.description.abstractLayered MnO2(δ-MnO2) was prepared by thermal decomposition of potassium permanganate.Ti was ion-implanted into such δ-MnO2 by physical techniques,forming a composite(δ-MnO2-Ti).These materials were characterized by XRD,SEM,XPS techniques and their electrochemical proprieties were investigated.The results showed that the layered structure of δ-MnO2 did not been destroyed after Ti ion implantation,and the implanted Ti element was mainly Ti4+ as indicated by XPS.Both of the first and the highest discharge specific capacities of the ion-implanted layered MnO2(δ-MnO2-Ti),compared to those of δ-MnO2,were improved significantly.zh_CN
