Molybdenum-Doped Manganese Dioxide for Use in Low Temperature Battery Cathodes.

摘要

A study of the chemical and electrochemical properties of manganese dioxide cathodes containing molybdenum trioxide is described. The manganese dioxide was made by the decomposition of a dossolved mixture of manganous nitrate and a small quantity of molybdenum trioxide. It was found that the chemical composition of the manganese dioxide was affected by the presence of less than 1% molybdenum trioxide. In certain cases, considerable improvement was observed in the discharge behavior of electrodes made with these oxides. The doped cathodes were assessed in the Zn/H2SO4/MnO2 reserve-primary system.
