Silver(II) oxide cell and its manufacture |
摘要 |
A silver(II) oxide cell which comprises a positive electrode comprising a shaped body of silver(II) oxide as a positive active material, a negative electrode comprising zinc as a negative active material and an alkaline electrolyte, characterized in that the shaped body is a molding product of a composition comprising particles of which each particle comprises a core part of silver(II) oxide and a surface part of silver(I) oxide integrally and continuously provided around the core part, the weight ratio of the silver(II) oxide and the silver(I) oxide being from about 70 : 30 to 90 : 10. Such silver(II) oxide cell has large discharge capacity and shows a flat and even discharge characteristics without any substantial deterioration in performances on storage.
