Title: (EN) ELECTROLYTE SOLUTION FOR ELECTROLYTIC CAPACITOR AND ELECTROLYTIC CAPACITOR UTILIZING SAID ELECTROLYTE SOLUTION
(ZH) 电解电容器用的电解液及使用所述电解液的电解电容器
Abstract:
(EN) The purpose of the present invention is to provide an electrolyte solution for an electrolytic capacitor which has high withstand voltage. The electrolyte solution for an electrolytic capacitor that is used contains a solvent which contains gamma-butyrolactone; an acrylic polymer which has a hydroxy group and/or a carboxy group; and an electrolyte. The acrylic polymer which has a hydroxy group and/or a carboxy group is preferably a polymer which has, as essential constituent monomers, a monomer having a (meth)acryloyl group and a hydroxy group, and/or a monomer having a (meth) acryloyl group and a carboxy group.
(ZH) 本发明的目的在于提供一种具有高的耐受电压的电解电容器用的电解液。本发明使用含有:包含γ‑丁内酯的溶剂、具有羟基及羧基的丙烯酸聚合体、以及电解质的电解电容器用的电解液。所述具有羟基及羧基的丙烯酸聚合体优选为以具有(甲基)丙烯酰基及羟基的单体、以及具有(甲基)丙烯酰基及羧基的单体作为必需构成单体的聚合体。
