Description
その理由は、エチレングリコールを主溶媒とする電解液中で、t−ブチルパーオキシラウレートのエーテル基部分が電極箔の酸化皮膜と反応して耐水性の皮膜を形成するため、電解液と電極箔との化学反応が抑えられ、耐電圧の向上を図ることができると考えられる。
しかも、t−ブチルパーオキシラウレートは、エチレングリコールを主成分とする溶媒に対して溶解性が高いため、多量に添加することができ、かつ、電解液を調製する際、電解液の加熱と攪拌が短時間で済む。
さらに、t−ブチルパーオキシラウレートは、主溶質のカルボン酸とのエステル化反応が少ない。
従って、本発明に係る電解液によれば、低比抵抗化および耐電圧の上昇の双方を図ることができる。
また、本発明に係る電解液を用いたアルミニウム電解コンデンサは、熱安定性に優れるため、アルミニウム電解コンデンサの信頼性を向上することができる。
