Separator for alkaline secondary battery |
| abstract |
(57) An object of the present invention is to provide a separator for an alkaline secondary battery that is excellent in alkali resistance, oxidation resistance, and self-discharge characteristics and can be made into a thin film. In a separator for an alkaline secondary battery using an ultrahigh molecular weight polyethylene porous sheet, one sulfonic acid group per 20 to 1100 ethylene monomer units is added to the ultrahigh molecular weight polyethylene porous sheet. Sulfonation treatment is performed so that The sulfonation treatment can be carried out by a gas phase method using anhydrous sulfuric acid, The amount of sulfonic acid group introduced can be adjusted by adjusting the contact time between the ultrahigh molecular weight polyethylene porous sheet and sulfuric anhydride gas. |
