Description
また、上記発明において、前記第三の電極は、銀-塩化銀電極、白金電極、リチウム電極から選ばれる参照電極であることが好ましい。
(電極の作製)
比表面積が1800m2/gの活性炭1.0g、ケッチェンブラック0.1g、ポリフッ化ビニリデン0.1gを乳鉢にて混合・混練し、これにN−メチル−2−ピロリドンを適量添加し、粘度調整を行ったスラリー溶液を得た。このスラリー溶液を0.04mm厚のアルミ箔上に片面塗布し、その後120℃、2時間乾燥し、電極層厚0.08mmの片面電極シートを作製した。また、0.05mm厚のアルミ箔上に両面塗布し、その後120℃、2時間乾燥し、電極層厚0.08mmの両面電極シートを作製した。得られた電極シートを規定の大きさに成形し、片面活性炭電極および両面活性炭電極とした。このとき、各電極シートの一端に凸形状を有する外部電極引き出しタブを設けた。
負極3の片面活性炭電極を両端に、両面活性炭電極を二枚の活性炭電極間に厚さ0.05mm厚のセルロース製セパレータ4を挟みながら規定枚数積層し電極素子とした。正極2および負極3ごとに、外部電極引き出しタブを集合し、各々にアルミ板からなるリード端子6、7を超音波溶接により取り付けた。この電極素子5の外周に厚さ0.05mm厚のセルロース製セパレータ4を巻き回し、アルミ製ラミネートフィルムからなる外装体10内に電極素子5を収容した。このとき、外装体10の四辺ある端部のうち一辺に開口部を設けるように外装体10の端部を熱シールした。外装体10の開口部と電極素子5との間には、第三の電極8を収容するためのスペースを設けた。
