Abstract
【解決手段】 ジメチルカーボネート(DMC)及びプロピレンカーボネート(PC)の混合溶媒、好ましくは、DMC:PCの容量混合比率が10:90乃至40:60の混合溶媒に、電解質として一般式〔1〕で表されるテトラフルオロホウ酸第4級スピロアンモニウムを溶解させた電気二重層キャパシタ用電解液であり、また、該電解液を用いて作製された電気二重層キャパシタである。
(式中、X及びYは、炭素数1〜4のアルキル基またはハロゲンを、k及びiは、0または1〜4の正整数を、n及びmは、炭素数3〜7のメチレン鎖を表す。)
【選択図】 なし
Description
DMC及びPCの容量混合比率が30:70の溶媒に、電解質であるPSP−BF4を溶解させて、濃度1.5mol/Lの電気二重層キャパシタ用電解液(以下、「PSP−BF4/DMC+PC」と略記する。)を調製した。該電解液の温度30℃における粘性率及び電導度の測定値を表1に示す。
実施例において、電解液として、濃度1.5mol/LのPSP−BF4を電解質とするPC溶液(以下、「PSP−BF4/PC」と略記する。)を用いた以外は、実施例と同様にして、電気二重層キャパシタ用電解液を得、粘性率及び電導度を測定した結果を比較例1に、同様に、電解液として、濃度1.5mol/LのTEMA−BF4を電解質とするPC溶液(以下、「TEMA−BF4/PC」と略記する。)を用いた結果を比較例2として、表1に示す。また、得られた電解液を用いた以外は、実施例と同様にして電気二重層キャパシタを作製し、長期信頼性試験を行った結果を表2に示す。
Claims (3)
- ジメチルカーボネート及びプロピレンカーボネートの容量混合比率が、10:90乃至40:60であることを特徴とする請求項1に記載の電気二重層キャパシタ用電解液。
- 請求項1または請求項2のいずれかに記載の電気二重層キャパシタ用電解液を用いて作製されてなることを特徴とする電気二重層キャパシタ。
