Title:
SEPARATOR FOR ALUMINIUM ELECTROLYTIC CAPACITOR, AND ALUMINIUM ELECTROLYTIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2014/098180
Kind Code:
A1
Abstract:
[Problem] To provide a separator for an aluminium electrolytic capacitor and an aluminium electrolytic capacitor, the separator exhibiting excellent impedance characteristics and short-circuiting resistance, and comprising a cellulose porous membrane manufactured using an amine oxide cellulose solution.
[Solution] A separator for an aluminium electrolytic capacitor and an aluminium electrolytic capacitor that is characterised by using the separator, the separator being formed from a cellulose porous membrane that comprises regenerated cellulose that has been dissolved and regenerated without forming a cellulose derivative, the cellulose porous membrane comprising regenerated cellulose that is obtained by forming a cellulose solution, which is cellulose dissolved in an amine oxide solvent or the like, into a membrane, solidifying and regenerating cellulose by immersing the membrane in water or a poor solvent of an amine oxide solvent, and, after having removed the amine oxide solvent from the regenerated cellulose, drying the result.
