Description
例1― 黒鉛アノード(比較例)
比較のためのアノードの形成では、グラファイト粉(Aldrich)100g、カーボンブラック(Cabot Corporation)2g、ポリフッ化ビニリデン(PVDF)(Alfa Aesar)10g、およびN−メチル−2−ピロリドン(NMP)溶媒(Sigma−Aldrich)190gを混合して、滑らかなスラリーを形成することにより、グラファイトスラリーを調製した。スラリーは、ドクターブレードを用いて、銅箔上に約1mmの厚さに分散した。グラファイトスラリーで被覆した銅箔は、最初に換気フードで乾燥し、120℃のオーブンで真空乾燥した後、直径1.4cmの電極になるように賽の目状に切断した。黒鉛電極(黒鉛+銅の集電体)の典型的な厚さは、約17mmであった。
例2―LTO(チタン酸リチウム)アノード(比較例)
LTO電極インクは、0.40gのLTO(Aldrich)、0.05gのカーボンブラック(Cabot Corporation)、0.05gのPVDF、および4.00gのNMPを乳鉢で混合することにより調製した。インク混合物は、ピペットを用いて銅箔(25マイクロメートル)上に分散し、大気雰囲気下で2日間乾燥した。得られた電極シートは、さらに真空オーブンにて120℃で一晩乾燥した。乾燥電極シートは、直径1.4cmのディスク状に切断した。
粉砕したフェノール樹脂を、200℃/時間の加熱速度で1000℃まで加熱し、1000℃で2時間保持して樹脂を炭化した後、室温まで冷却した。熱サイクルは、窒素雰囲気下にて、6.18リットル/分のガス流量で行った。得られた炭素は、37%の塩酸に一晩浸漬させ、脱イオン水で水洗し痕跡不純物を除去した。試料を、さらに29%のNH4OH水溶液に一晩浸漬させた後、脱イオン水で水洗した。浄化された硬質炭素は、窒素雰囲気下で、1000℃で2時間加熱した。炭素スラリーは、42.5gの得られた硬質炭素粉、5gのPVDF、2.5gのカーボンブラックおよび120mlのNMP溶媒を用いて調製した。
例3を、複合電極に20重量%のLTOを用いて繰り返した。
例5―LTO38.6%含有の硬質炭素複合アノード
例3を、複合電極に38.6重量%のLTOを用いて繰り返した。
図6は、例2から例5のラゴンプロット(出力密度対エネルギー密度)である。図6のデータは、例3から例5の本発明の複合アノードをベースにしたキャパシタが、例2のLTOアノードキャパシタと比べてエネルギー密度および出力密度が高いことを示している。さらに、20重量%のLTO複合アノードのエネルギー密度および出力密度は、14.6重量%の複合アノードと38.6重量%の複合アノードの場合のエネルギー密度および出力密度より高かった。
