Title:
【発明の名称】高放電電解二酸化マンガン及び電極並びにこれを組み入れたアルカリ電池
Document Type and Number:
Japanese Patent JP2003506849
Kind Code:
A
Abstract:
An alkaline electrochemical cell is disclosed having a positive electrode, a negative electrode, and an electrolyte. The positive electrode comprises electrolytic manganese dioxide having a pH-voltage of at least about 0.860 volt. The electrolytic manganese dioxide also preferably has less than about 250 ppm and more preferably less than about 150 ppm of potassium impurities by weight. Electrolytic manganese dioxide having these properties exhibits significant synergistic and unexpected improvements in high-rate service, which translates to improved high-rate service life of the electrochemical cell containing the improved electrolytic manganese dioxide in its positive electrode.
