用锌离子吸附（ＺＩＡ）法、模拟电池放电实验、ＸＲＤ技术研究从高品位低活性天然二氧化锰（ＮＭＤ）制得的活化天然二氧化锰（ＡＮＭＤ）产品的比表面积、放电行为以及晶体结构等物理化学性能．实验结果表明，ＡＮＭＤ具有大的比表面积、高的放电活性，其晶型属于α－ＭｎＯ２．与ＮＭＤ相比，ＡＮＭＤ的比表面从ＮＭＤ的８．９ｍ２／ｇ提高到６０．１ｍ２／ｇ，放电容量在ＮＨ４Ｃｌ＋ＺｎＣｌ２介质中从ＮＭＤ的１４．０ｍＡ·ｈ提高到２３．２ｍＡ·ｈ，在ＫＯＨ介质中从ＮＭＤ的１６．０ｍＡ·ｈ提高到２９．１ｍＡ·ｈ．ＡＮＭＤ的放电性能接近电解二氧化锰（ＥＭＤ）的水平。
The specific surface area, discharge behavior and crystal structure of activated natural manganese dioxide (ANMD) prepared from high-grade low-activity natural manganese dioxide (NMD) were studied by means of zinc ion adsorption (ZIA), simulated battery discharge and XRD Other physical and chemical properties. Experimental results show that, ANMD has a large specific surface area, high discharge activity, the crystal belongs to α-MnO2. Compared with NMD, the specific surface area of ANMD increased from 8.9m2 / g to 60.1m2 / g and the discharge capacity increased from 14.0mA · h to 23.2mA · h in NH4Cl + ZnCl2 medium in NH4Cl + Increased from 16.0 mAh of NMD to 29.1 mAh. The discharge performance of ANMD is close to the level of electrolytic manganese dioxide (EMD).
