电池用EMD的晶粒度和物相组成

Crystal Size and Phase Components of Electrolytic Manganese Dioxide Used in Battery

本文用D/max-rC型转靶×射线衍射仪和扫描电镜对不同产地EMD的晶型、物相及晶粒尺寸进行了测定和计算,并结合制成电池的放电性能数据进行了比较,给出了最佳晶粒尺寸范围和γ/β型二氧化锰含量比。

A study of crystal structure , phase components and crystal size of elctrolytic manganese dioxide samples from various sources was performed on a D/max-rC rotating anode X-ray diffractometer and a scanning electron microscope. The results were compared with their behavior on discharge characteristics of batteries. Optimum crystal size and a ratio of gamma and beta phases were given in the final conclusion.
