Title:

SEPARATOR FOR CAPACITOR, AND CAPACITOR

Document Type and Number:

Japanese Patent JP2009099836

Kind Code:

A

Abstract:

To provide a separator for a capacitor which has superior heat resistance, superior blocking performance for electrode substances etc., peeled off from plus and negative electrodes, large voidage and superior passing property for an electrolyte, and superior dynamic characteristics, durability and handling property.

(i) The separator for the capacitor includes a stack which has a nonofiber layer inside and has protective layers on both surfaces. (ii) The nanofiber layer is formed of polyamide filaments of 10 to 600 nm in average fiber diameter comprising polyamide (1), 60 mol% of dicarboxylic acid units being terephthalic acid units and 60 mol% of diamine units being 1,9-nanodiamine units and/or 2-methyl-1,8-octane diamine units. (iii) The protective layers are formed of fibers containing polyamide (a) fibers, 60 mol% of dicarboxylic acid units being terephthalic acid units and 60 mol% of diamine units being 1,9-nanodiamine units and/or 2-methyl-1,8-octane diamine units.
