PURPOSE: To enhance stability, and particularly lengthen the cycle service life of a secondary battery by forming an alkaline battery having a separator. CONSTITUTION: A separator for an alkaline battery which is substantially formed of a cross linked body obtained by cross-linking polyvinyl alcohol under the existence of a cross-linking agent and on which the cross-linking agent 13 sodium tetraboric acid and/or its hydrate and whose cross-linked body is formed independently or integrally with a mesh-like structure body and is characterized by having a sheet-like shape or the like and an alkaline battery having these, are provided. A separator is excellent in electrolyte resistance, dendrite resistance and an electrolyte keeping characteristic, and is useful since ion conductivity is excellent. |
