Description
すなわち、本発明に係る電解コンデンサの駆動用電解液では、エチレングリコールを主成分とする溶媒に、少なくとも、有機カルボン酸またはその塩と、以下の化学式で示されるtert−ブチル−2−ヒドロキシオクタネートとを配合し、前記tert−ブチル−2−ヒドロキシオクタネートの配合量が、電解液全体に対して0.1〜5.0重量%であることを特徴とする。
ここで、tert−ブチル−2−ヒドロキシオクタネートの配合量は、電解液全体に対して0.1〜5.0重量%であることが好ましい。
また、電解液にはホウ酸またはその塩を配合することもある。
その理由として、tert−ブチル−2−ヒドロキシオクタネートは還元作用を有しており、陽極においてtert−ブチル−2−ヒドロキシオクタネートが酸化して陽極酸化皮膜に吸着し、陽極酸化皮膜を保護するため、電解コンデンサの漏れ電流上昇を抑制できると考えられる。
