Electrodes, alkaline secondary battery, and method for manufacturing alkaline secondary battery

摘要

An alkaline secondary battery which is characterized in that it comprises, a positive electrode containing nickel hydroxide having a value of 0.8° or more in the half-width of a peak in the (101) plane thereof as measured by X-ray powder diffraction (2theta) using Cu-Kalpha ray, and 4.0 to 15% by weight of at least one material selected from the group consisting of zinc and zinc compounds, and an alkali electrolyte, the ratio of which to theoretical capacity of the positive electrode being 0.7 to 2.0 cm3/Ah, the weight of the at least one material being one calculated as zinc element and based on the weight of the nickel hydroxide.
