Abstract
(EN) An electrolytic solution for electric double layer capacitor characterized in that a spiro compound of formula (1) is contained as an electrolyte in an aprotic solvent and that the electric conductivity thereof at -40°C is 0.85 mS/cm or higher. This electrolytic solution for electric double layer capacitor realizes a high dissolution of electrolyte in solvent and exhibits excellent conductivity and electrostatic capacity over a wide temperature range from low to high temperature. Further, the electrolytic solution for electric double layer capacitor exhibits high resistance to voltage and even under long-term high voltage load, exhibits suppressed lowering of electrostatic capacity to thereby excel in long-term reliability.
(FR) Solution électrolytique pour un condensateur électrique à double couche, caractérisée en ce qu'un composé spiro de formule (1) est contenu en tant qu'électrolyte dans un solvant aprotique et en ce que la conductivité électrique de ladite solution à 40 °C est de 0,85 mS / cm ou plus. Cette solution électrolytique pour un condensateur électrique à double couche présente une forte dissolution de l'électrolyte dans le solvant et une conductivité ainsi qu'une capacité électrostatique excellentes sur une large plage de températures, de températures basses à des températures élevées. En outre, ladite solution électrolytique pour condensateur électrique à double couche possède une grande résistance à la tension, même en cas de charges de tension élevées et à long terme, ainsi qu'une suppression de la baisse de capacité électrostatique, ce qui confère à ladite solution une excellente fiabilité à long terme.
(JA)  非プロトン性溶媒中に、式(1)で表されるスピロ化合物を電解質として含有し、その電導度が、−40℃において、0.85mS/cm以上であることを特徴とする電気二重層キャパシタ用電解液である。本発明の電気二重層キャパシタ用電解液は、電解質の溶媒への溶解度が高く、低温から高温に至るまでの広い温度範囲で優れた電導度と静電容量を示し、耐電圧が高く、長期間の高電圧負荷によっても静電容量が低下しにくく長期信頼性に優れている。
