摘要

PURPOSE: A compound is provided to improve the content of phosphoric acids and mechanical properties and to improve voltage characteristics and cell performances in a high current density region. CONSTITUTION: A compound is represented by chemical formula 1. In chemical formula 1, Ar is a substituted or unsubstituted C6-C20 arylene group or a substituted or unsubstituted C3-C20 hetero arylene group, and n is a number from 1 to 300. A cross-linked material is obtained through a cross-linking reaction of a compound represented by chemical formula 1, wherein the cross-linking reaction is a cross-linking reaction between the compound represented by chemical formula 1, or a cross-linking reaction between the compound represented by chemical formula 1 and at least one carboxylic acid compound selected from the group consisting of aromatic tricarboxylic acid, heteroaromatic tricarboxylic acid, aromatic tetracarboxylic acid, and heteroaromatic tetracarboxylic acid.
