Beschreibung
Zusammenfassung:	This alkaline secondary cell disclosed with this application includes a positive electrode comprising a positive electrode mixture layer that contains silver oxide; a negative electrode; and an alkaline electrolyte, wherein the positive electrode mixture layer further contains insulating inorganic particles and carbon particles, and contains graphite particles and carbon black particles as the carbon particles, the negative electrode contains zinc-based particles selected from zinc particles and zinc alloy particles, and the alkaline electrolyte contains potassium hydroxide or sodium hydroxide, lithium hydroxide, and polyalkylene glycols. Also, with a charging method and charging device of the alkaline secondary cell disclosed with this application, the charging voltage during constant voltage charging is set to a voltage for which with the positive electrode, an oxidation reaction progresses from silver to silver oxide (I), but the oxidation reaction does not progress from silver oxide (I) to silver oxide (II).
