| 摘 要： | <正> MnO_2是锌—锰干电池正极的活性物质,它对电池的放电容量起着决定性的作用。我国MnO_2矿源颇多,但其活性良莠不齐。长期以,来国内在电池工业中评价 MnO_2的质量均须制成实样电池进行放电实验。耗费人力和时间很多,而化学分析结果却往往又不足以作为判断之依据。基于这种情况,有必要寻找一种鉴定 MnO_2质量的简便快速、行之有效的方法,以推

Relationship between pH—MnO_2 Potential and Activity of Manganese Dioxide for Dry Battery |
| |
| Abstract: | This paper presents an electrochemical evaluation of MnO_2 for dry battery use.We have determined the PH—potential relation of MnO_2 made from five ores,and actual zinc—manganese dry batteries were made with eaeh of them Then Determined its capacity of discharge,compared the MnO_2 potential with the capacity,we have obtained an eleetrochemical evalation of manganese dioxide for dry btatery use. |
