Description
本開示は、電気化学キャパシタ又は電気化学セル等のエネルギー貯蔵装置に有用であり得る電気化学的導電性物品に関する。
化石燃料の利用可能性の減少に対する懸念から、将来のエネルギー需要のために風力及び太陽光等の自然動力源を使用することへの関心が高まりつつある。これらの動力源のいくつかは、継続的にエネルギーを生産しない。例えば、風が常に吹くとは限らず、また太陽が常時照るとは限らない。したがって、エネルギー貯蔵装置及びシステムが、エネルギー生産の中断時間の間、これらの自然動力源から集められたエネルギーの使用を可能にするために、ますます需要のあるものとなっている。
例えば、リチウムイオン電気化学セル又は電気化学キャパシタに使用するための、高導電率及び高表面積を有する導電性電極等の導電性物品が必要である。単純かつ経済的である、そのような導電性物品を生産する方法も必要である。最後に、高いエネルギー容量及び高い電源供給率を提供するためのエネルギー貯蔵システムに使用され得る導電性物品が必要である。
「活性」又は「電気的に活性」は、リチウムが可逆的に挿入され、電気化学的手段によって取り出され得る材料を指す。
以下の説明において、本明細書の説明の一部を構成し、いくつかの特定の実施形態が例として示される添付の一連の図面を参照する。本発明の範囲又は趣旨を逸脱せずに、その他の実施形態が考えられ、実施され得ることを理解すべきである。したがって、以下の詳細な説明は、限定的な意味で解釈されるべきではない。
C=εrεoA/d
等式(1)
式中、εrが電解質の誘電率であり、εoが真空の誘電率であり、dが二重層の有効厚さ(電荷分離距離)であり、Aが電極表面積である。キャパシタンスの量、Cは、電極表面に正比例し、電荷分離距離に反比例する。
厚さ20マイクロメートルのエッチングされたアルミニウム箔のシート(15.3cm×26.7cm、Toyo Aluminum K.K,Japanから入手可能)は、接着テープを有するガラスプレートに付着された。HSAG300グラファイト粉末(Timcal,Bodio,Switzerlandから入手可能)は、この箔の上にランダムに散布された。塗料パッド(Shur−Line,Huntesville,NC.のEZ Paintr)と適合されたMakitaシート仕上げ研磨機(Makita Company,Whitby.Ontario,CanadaのモデルBO4900V)を使用し、2の速度設定で、研磨機を手動で前後に動かすことによって、この箔を研磨した。この研磨機は、均一な灰色着色のコーティングが箔の上に堆積されたことが認められた時点の8秒後に、この箔から取り出された。
実施例と同様の方法が、異なる持続時間(8秒、15秒、及び30秒)のバフコーティングを使用してエッチングされたアルミニウムをコーティングするために使用された。試料の全てを、電流コレクタとして確実に検査した。
Claims (3)
- 電流コレクタと、
前記電流コレクタと接触するグラファイトコーティングと、を備え、
前記グラファイトコーティングが、結合剤を含まず、
前記電流コレクタが、多孔質金属を含み、
