Description
市販の電流コレクタ(Exopack,米国ニースカロライナ州マシューズ(Matthews))の両面に基準活性炭素層を室温で積層した。活性炭素層厚は約250μmである。本実施例に、また以下の実施例にも、用いられる基準活性炭素層は、市販の活性炭素材料(クラレカーボン社(Kuraray Carbon Inc.),日本国大阪府)を含み、活性炭素材料は、85重量%の活性炭素材料、5重量%のカーボンブラック及び10重量%の「テフロン」(PTFE)の比で、カーボンブラック及び結合剤と組み合わせた。
重量部がほぼ等しいカーボンブラック及びグラファイトを含む導電性インクの水性スラリーをアルミニウム1145H19ホイルの両面上にディップコーティングした。それぞれの導電性密着層の平均厚は約1〜3μmであった。導電性密着層に重ねて基準活性炭素層を200℃の積層温度及び250psi(1.72×106Pa)の積層圧力で積層した。活性炭素層の厚さは約250μmであった。得られた電極の、形成されたままの状態の膜厚方向面積比抵抗は0.04Ω-cm2であった。150℃16時間の熱処理後の膜厚方向面積比抵抗は0.05Ω-cm2であった。
日本国東京都のKDKコーポレーションから市販されている、予エッチングされたアルミニウム電流コレクタを用いて、実施例2の実験を繰り返した。基板はそれぞれのエッチング手続きの,G571,C208またはC209で指定される。G571に対応するアルミニウムは約75μm厚であり、C208及びC208に対するアルミニウムは約50μm厚である。基準活性化炭素層の積層後、膜厚方向面積比抵抗は、形成されたままの状態の電極及びストレス試験後の電極のいずれについても0.05〜0.06Ω-cm2の範囲にわたって変動した。
従来の電流コレクタの代わりに50μm厚融合炭素被覆アルミニウムシート(東洋炭素,日本国大阪府)を用いて実施例2の実験を繰り返した。融合炭素被覆の平均厚は1μm未満である。膜厚方向面積比抵抗は、15℃-16時間ストレス試験の前及び後のいずれにおいても0.03Ω-cm2であった。多層電極構造への融合炭素被覆電流コレクタの導入はアルミニウムと活性炭素の間の界面における界面抵抗を実質的に低減する。実施形態において、両面多層電極の膜厚方向面積比抵抗は0.1Ω-cm2未満であった。
活性炭素層にNLC活性炭素(85重量%のNLC活性炭素、5重量%のカーボンブラック及び10重量%のPTFE結合剤)を用いてウルトラキャパして試験セルを作成した。この活性炭素層を実施例2のディップコーティング電流コレクタに重ねて積層した。得られたセルのRC時定数は1.3秒と1.5秒の間であり、ほぼ500Fのキャパシタンスを示した。
実施例1〜6の膜厚方向面積比抵抗データ及び実施例AとBの実験試験セルデータに基づいて、本明細書に説明されるような多層電極を備える試験セルのモデルをつくり、対応する試験セル統計を計算した。多層電極を備え、活性炭素層にNLC炭素を含む、試験セルについて得られたRC時定数は約1秒と推定され、これは驚くべき有益な結果であり、モデルの構造により、高エネルギー密度及び高電力密度のいずれをも有する素子が可能になるであろうことを示唆している。
