Abstract
【解決手段】基板に装着される電気二重層キャパシタが、電解液を有するセパレータとガスケットを備え、電解液にプロピレンカーボネート(PC)を、ガスケットにテトラフルオロエチレンパーフルオロアルキルビニルエーテル共重合体(PFA)を用いる。
【選択図】 図1
Description
前記有機溶媒はプロピレンカーボネート(PC)を含み、且つ、前記ガスケットはテトラフルオロエチレンパーフルオロアルキルビニルエーテル共重体(PFA)からなることを特徴とする。
活性炭とアセチレンブラックとポリテトラフルオロエチレンとを90:5:5の重量比になるように混合し、該混合物を直径10mm、厚さ0.5mmの円板状に成形した後、150℃で2時間真空乾燥させて分極性電極を作製した。
プロピレンカーボネートとγ‐ブチロラクトンとを5:95の体積比で混合させた有機溶媒に、支持塩であるテトラエチルアンモニウムテトラフルオロボーレイト((C2H5)4NBF4)を1.0mol/lの濃度になるように溶解させて電解液を作製した。
図1に示すように、ステンレス製のコイン缶(蓋)4a、コイン缶(ケース)4bの底面に集電体5、6として黒鉛粉末と水ガラスとを混合した導電塗料を塗布した後、前記分極性電極を載置する。そして、分極性電極2の上面に前記電解液を含んだガラス繊維のセパレータ3を載置し、前記コイン缶(ケース)4bの内側にテトラフルオロエチレンパーフルオロアルキルビニルエーテル共重合体からなるガスケット7を装着させてコイン缶(蓋)4aを被せた後、かしめ封止させて電気二重層キャパシタを作製した。
