【摘要】 从MnCl₂溶液在不同条件下电解制备出八个纤维态电解二氧化锰（FEMD）样品（No.1,No.2.No.4…No.9）,把这些样品和我国及日本制造的电解二氧化锰（EMD）分别制成R₂₀型干电池,进行放电时间的比较,其结果指出FEMD远比EMD优越,尤其是在高电压范围（终止电压1.0—0.95伏）的重电流放电。此外,还研究了FEMD的某些特性。更多还原

【Abstract】 Eight samples of FEMD （№.1,№.2,№.4-№.9） prepared from various onditions of electrolyzing MnCl₂ solutions and samples of EMD made in China nd Japan have been used for manufacturing R₂₀ dry cells. The comparison of ischarge time of these dry cells showed that the FEMD samples are far more uperior than the EMD,especially during heavy current discharge in the range f higher voltage （e. g. at ending voltage 1.0-0.95 volt）. Some characteristic properties of FEMD were studied.更多还原
