Abstract
There is provided a nickel electrode for an alkaline secondary battery, in which the coefficient of use of nickel hydroxide, which is an active substance, is high, the swell restricting effect is high, and the charging/discharging cycle life characteristic is high. The nickel electrode is formed by filling a conductive, porous substance of a three-dimensional network structure with a mixture containing an active substance consisting mainly of nickel hydroxide. The nickel hydroxide is such that, when thermogravimetric analysis is performed at a heating rate of 10.degree. C./min and the TG curve is plotted, the value obtained by subtracting the weight decrease percentage at a temperature of T.degree.C. at which the DTG curve, the differential curve of the TG curve, turns to an upward curve from the weight decrease percentage of the nickel hydroxide at a temperature of 100.degree. C. is 0.6 to 1.5%.
