钴掺杂多孔锰氧化物自组装花球制备及其超电容特性研究
Preparation of cobalt-doped porous manganese oxides microsphere and its properties as supercapacitor electrode materials
摘要
Abstract
Flower-liked MnO2 nanospheres with different contents of cobalt ion were prepared by hydrothemal method. The actrual discharge capacity of manganese oxides and the effect of cobalt ion content on its elctrochemical performance were studied. XRD, SEM and electrochemical technique were used to characterize the samples' structure, morphology and electrochemical property. The XRD analysis shows that cobalt ions are uniformly doped into the middle of manganese oxides. The SEM images indicate that the flower-liked nanosphere, which the samples present, is composed of nano-lamellar structure. Compared with Co-doped materials, the particle size of the pure nanospheres is not homogeneous. The test results display that the size of obtained materials becomes smaller and its surface appears more loosened with the mole fraction of Co doping reaching to 10%. The small size makes electrolyte easier to acess to materials and the utlization of samples to some extent. The charge-discharge test shows that specifc capacity of the optimized sample can be up to 410.158 F·g–1.关键词
