PROBLEM TO BE SOLVED: To provide a separator containing a certain amount of inorganic oxide, thereby enhancing the electrolyte-retaining property of the separator, and improving the long-term cycle life characteristics and charge / discharge characteristics at high temperatures. Provide the next battery. SOLUTION: It is selected from the group of inorganic oxides consisting of calcium oxide, aluminum oxide, manganese oxide, magnesium oxide, tin oxide, nickel oxide, cobalt oxide, yttrium oxide, ytterbium oxide, zinc oxide, vanadium oxide and silicon dioxide. A separator for an alkaline secondary battery in which at least one kind is present. |
