Description
アルミニウム多孔体の製造方法を説明する。まず連通気孔を有する樹脂多孔体を準備する。樹脂多孔体の素材はアルミニウムの融点以下の温度で分解可能なものであれば任意の樹脂を選択できる。ポリウレタン、ポリプロピレン、ポリエチレン等が樹脂多孔体の素材として例示できる。なお樹脂多孔体と表記したが、連通気孔を有するものであれば任意の形状の樹脂を選択できる。例えば繊維状の樹脂を絡めて不織布のような形状を有するものも樹脂多孔体に代えて使用可能である。樹脂多孔体の気孔率は80%〜98%、気孔径は50μm〜500μmとするのが好ましい。発泡ウレタンは気孔率が高く、また気孔の連通性、孔径の均一性があるとともに熱分解性にも優れているため樹脂多孔体として好ましく使用できる。
次にアルミニウム多孔体を用いた電池用電極材料及び電池について説明する。例えばリチウムイオン電池の正極に使用する場合は、活物質としてコバルト酸リチウム(LiCoO2)、マンガン酸リチウム(LiMn2O4)、ニッケル酸リチウム(LiNiO2)等を使用する。活物質は導電助剤及びバインダーと組み合わせて使用する。従来のリチウムイオン電池用正極材料は、アルミニウム箔の表面に活物質を塗布している。単位面積当たりの電池容量を向上するために、活物質の塗布厚みを厚くしている。また活物質を有効に利用するためにはアルミニウム箔と活物質とが電気的に接触している必要があるので活物質は導電助剤と混合して用いられている。これに対し、本発明のアルミニウム多孔体は気孔率が高く単位面積当たりの表面積が大きい。よって多孔体の表面に薄く活物質を担持させても活物質を有効に利用でき、電池の容量を向上できるとともに、導電助剤の混合量を少なくすることができる。
アルミニウム多孔体は、電気二重層コンデンサ用の電極材料として使用することもできる。アルミニウム多孔体を電気二重層コンデンサ用の電極材料として使用する場合は、電極活物質として活性炭等を使用する。活性炭は導電助剤やバインダーと組み合わせて使用する。導電助剤としては黒鉛、カーボンナノチューブ等が使用できる。またバインダーとしてはポリテトラフルオロエチレン(PTFE)、スチレンブタジエンゴム等を使用できる。
(アルミニウム多孔体の製造:蒸着法によるアルミニウム層の形成)
以下、アルミニウム多孔体の製造例を具体的に説明する。樹脂多孔体として、気孔率97%、気孔径約300μmのポリウレタンフォーム(厚み1mm)を準備し、20mm角に切断した。ポリウレタンフォームの表面にアルミニウムを蒸着し、厚み15μmのアルミニウム層を形成した。
アルミニウム層を形成した樹脂多孔体を温度500℃のLiCl−KCl共晶溶融塩に浸漬し、−1Vの負電位を30分間印加した。溶融塩中に気泡が発生し、ポリウレタンの分解反応が起こっていると推定された。その後大気中で室温まで冷却した後、水洗して溶融塩を除去し、アルミニウム多孔体を得た。得られたアルミニウム多孔体のSEM写真を図6に示す。図6より、得られたアルミニウム多孔体は連通気孔を有し、気孔率が高いことがわかる。また得られたアルミニウム多孔体の表面を15kVの加速電圧でEDX分析した結果を図7に示す。酸素のピークはほとんど観測されず、アルミニウム多孔体の酸素量はEDXの検出限界(3.1質量%)以下であることがわかる。さらに得られたアルミニウム多孔体を用いて電池としての評価を行ったところ、良好に作動することが確認できた。
樹脂多孔体として、気孔率97%、気孔径約300μmのポリウレタンフォーム(厚み1mm)を準備し、幅100mm、長さ200mmに切断した。ポリウレタンフォームの表面にアルミニウムを蒸着し、厚み15μmのアルミニウム層を形成した。幅160mm、長さ430mm、深さ80mmで厚みが10mmのアルミニウム漕にLiCl−KCl共晶溶融塩を入れて温度500℃に加熱した。LiCl−KCl共晶溶融塩中に窒素ガスを流量3×10−4m3/秒で流しながら、アルミニウム層を形成した樹脂多孔体を溶融塩中に5分間浸漬した。アルミニウム層には−1.1Vの負電位を印加した。溶融塩中に気泡が発生し、ポリウレタンの分解反応が起こっていると推定された。その後大気中で室温まで冷却した後、水洗して溶融塩を除去し、アルミニウム多孔体を得た。得られたアルミニウム多孔体の表面を15kVの加速電圧でEDX分析したところ、酸素量は2.9質量%、炭素量は1.54質量%であった。
溶融塩中に窒素ガスを流さなかったこと以外は実施例2と同様の操作を行ってアルミニウム多孔体を作製し、評価した。酸素量は7.61質量%、炭素量は1.74質量%であった。溶融塩中に窒素ガスを流しながら樹脂の分解を行った実施例2と比較すると酸素量、炭素量共に若干多くなっている。
