電気化学素子用セパレータ

Abstract

<P>PROBLEM TO BE SOLVED: To provide a separator for an electrochemical element which is superior in heat resistance, favorable in handling, and small in pore diameter. <P>SOLUTION: (1) The separator for the electrochemical element is the separator so that interspaces of a fiber matrix are filled with aluminiumoxides and microfibrillated cellulose having a dispersed agglomeration diameter of smaller than 1 &mu;m, or (2) that interspaces of a fiber matrix are filled with aluminiumoxides, hydroxylated aluminiumoxides, and a microfibrillated cellulose and the dispersed agglomeration diameter of an agglomerated structure composed of the aluminiumoxid and hydroxylated aluminiumoxid is sam than 1 &mu;m. <P>COPYRIGHT: (C)2010,JPO&amp;INPIT
