Description
以上の問題に鑑みて、本発明の課題は、低比抵抗で、かつ、高温条件下で安定した電気特性を示す電解コンデンサ用の電解液を提供することにある。
すなわち、エチレングリコールと水とを混合した溶媒に、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シアヌル酸トリアリルエステルとを溶解し、該シアヌル酸トリアリルエステルの溶解量が電解液全体に対して0.1〜1.0wt%であり、かつ水の混合量が電解液全体に対して2.0〜10.0wt%であることを特徴とする電解コンデンサの駆動用電解液である。
ここで、シアヌル酸トリアリルエステルの溶解量は、0.1〜1.0wt%の範囲が好ましく、0.1wt%未満では水和防止に十分な効果が得られず、1.0wt%を超えると比抵抗が高くなり、低比抵抗用途に不向きとなる。
また、水の混合量は、2.0〜10.0wt%の範囲が好ましく、2.0wt%未満では比抵抗が高いので、低比抵抗用途に不向きであり、10.0wt%を超えると、シアヌル酸トリアリルエステルの水和防止効果が低下し、漏れ電流が増加するので、不適当である。
