    • A process for manufacture of manganese dioxide comprising subjecting an aqueous bath comprising manganese sulfate (MnSO 4 ) and sulfuric acid (H2S04) to electrolysis in a closed cell wherein the electrolysis bath is maintained at an elevated temperature above 110°C, preferably above 115°C and at superatmospheric pressure. Desirably the bath can be maintained at an elevated temperature between about 115°C and 155°C. The electrolysis is carried out preferably at elevated current density of between about 12.5 and 37 Amp/sq.ft (135 and 400 Amp/sq.meter) of the anode surface which allows for smaller or fewer electrolysis units. An MnO 2 product having a specific surface area (SSA) within desired range of between 18-45 m 2 /g can be obtained. A doping agent, preferably a soluble titanium dopant can also be employed to help obtain the desired specific surface area (SSA) of the MnO¿2¿ product. The manganese dioxide product when used as cathode active material in zinc/MnO 2 alkaline cells results in excellent service life, particularly when the cell is used in high power application.
    • 一种制造二氧化锰的方法,包括使包含硫酸锰(MnSO 4)和硫酸(H 2 SO 4)的水浴在封闭的电池中进行电解,其中电解浴保持在高于110℃,优选高于115℃的高温 并在超大气压下。 理想地,浴可以保持在约115℃和155℃之间的升高的温度。电解优选在升高的电流密度下进行,电流密度在约12.5和37安培/平方英尺之间(135和400安培/平方米) ),其允许更小或更少的电解单元。 可以获得具有在18-45m 2 / g之间的期望范围内的比表面积(SSA)的MnO 2产物。 还可以使用掺杂剂,优选可溶性钛掺杂剂来帮助获得所需的MnO 2产物的比表面积(SSA)。 当用作锌/锰氧化物碱性电池中的阴极活性材料时,二氧化锰产品具有优异的使用寿命,特别是当电池用于大功率应用时。
