Description
厚さ50μmの銅箔の両面をアチソン・コロイズ(Acheson Colloids B.V.)社の市販の懸濁液EB012(熱可塑性結合剤中のチキソトロピー性の黒鉛懸濁液)で被覆した。塗布に最適な粘度に調整するために該懸濁液中の固形分を水の添加によって30%から20%に減じた。被覆を簡単な積層ローラ(Kaschierwalze)により片面ずつ先ず表側に、そして2回目に通過させた際に裏側に行なった。該銅箔は、電池への適用のための市販の標準の箔である。液状塗装膜の厚さは、送り速度2.5m/分で約20μmであった。乾燥を約80℃で行なった。乾燥後に接着増進層の膜厚はなお4μmであった。引き続き、このようにして被覆された箔をエクスパンドメタルへとさらに加工した。引伸しは、短いほうの対角線が長さ1mmを有しかつ長いほうの対角線が長さ2mmを有するように調整した。得られた材料は剥離することはなく、また金属に亀裂もなく、かつ100%までが引き続き使用することができた。
実施例1を繰り返し、その際、引伸しは、短いほうの対角線は長さ1.5mmを有しかつ長いほうの対角線が長さ3mmを有するように調整した。製品において被覆に亀裂が見られ、数箇所で該被覆が剥離していた。不良率は面積割合で約30%であった。
実施例1を繰り返したが、但し、銅箔を最初にエクスパンドメタルに変え、そしてこれを上記のとおりに被覆した。得られた材料には、裂け目の入った箇所および被覆が剥離した箇所が多数、不均一に分布しているのが見られた。6ロット(ローラ処理)のうち全体で1つだけが、エクスパンドメタルを導電体にさらに加工するのに用いることができる程度に使用可能であった。全体として、エクスパンドメタルの50%を超える面積が損傷していた。
厚さ50μmのアルミニウム箔の両面を上記のアチソン・コロイズ社の市販の懸濁液EB012で被覆した。塗布に最適な粘度に調整するために該懸濁液中の固形分を水の添加によって30%から20%に減じた。被覆を簡単な積層ローラにより片面ずつ先ず表側に、そして2回目に通過させた際に裏側に行なった。該銅箔は、電池への適用のための市販の標準の箔である。液状塗装膜の厚さは、送り速度2m/分で約20μmであった。乾燥を約80℃で行なった。乾燥後に接着増進層の膜厚はなお4μmであった。引き続き、このようにして被覆された箔をエクスパンドメタルにさらに加工した。引伸しは、短いほうの対角線が長さ1mmを有しかつ長いほうの対角線が長さ2mmを有するように調整した。得られた材料は剥離することはなく、また金属に亀裂もなく、かつ100%までが引き続き使用することができた。
実施例2を繰り返し、その際、引伸しは、短いほうの対角線は長さ1.5mmを有しかつ長いほうの対角線が長さ3mmを有するように調整した。製品において被覆に亀裂が見られ、数箇所で該被覆が剥離していた。不良率は面積割合で約25%であった。
アノード箔を作製するために球状黒鉛MCMB1.7gに導電性カーボンブラック(アセチレンブラック)0.1g、共重合体(PVDF−HFP)を含むポリフッ化ビニリデン0.2gおよびアセトン2gを添加し、カッティング撹拌機(Schneidruehrer)を用いて均一に分散したペーストに加工した。該ペーストから引き続きドクターブレードを用いてガラス板上で箔を作製した。溶剤の蒸発後に自己支持形の箔が残留し、この箔をガラス板から取り除いた。乾燥膜の膜厚は、約100μmであった。
アノード箔と同様にして同じ大きさのカソード箔を次の組成で作製した。即ち、LiCoO2 3.6gに導電性カーボンブラック(アセチレンブラック)0.2gおよびPVDF0.2gならびにアセトン4gを添加した。該箔の膜厚は、同じく約100μmであった。
PVDF−HFP0.5gおよびアセトン2.4gを用いてセラミック充填材(リン酸リチウムアルミニウムチタン(Lithiumaluminiumtitanphosphat) Li1.3Al0.3Ti1.7(PO4)3)1.5gを(3)に記載されたとおりにして厚さ約50μmのセパレータ箔に加工した。
各導電格子への電極箔の積層をロールラミネータで行なった。この場合には箔を160℃で予熱し、次にロール下に圧搾力236kpで積層した。送り速度は40mm/秒であった。引き続いてのテープテストは、対応する導電格子への各箔の良好な接着が示していた。第2の積層ステップで3つの構成要素、銅導電格子を備えたアノード、アルミニウム導電格子を備えたカソードおよびセパレータ箔を貼り合せた。同じく積層温度160℃および送り速度20mm/秒で圧搾力は16kpであった。蓄電池本体の構造が図1および2に示されている。図1は蓄電池本体の断面図であり、それに対して図2は蓄電池本体の上面図を示している。図1には、貼り付けられたカソード箔(5)およびセパレータ箔(6)を伴った、接着増進剤で被覆されたアルミニウムエクスパンドメタル(4)が示されている。対向電極は、貼り付けられたカソード箔(7)を伴った、接着増進剤で被覆された銅エクスパンドメタル(8)から成る。図4の上面図の場合には、アルミニウムエクスパンドメタル(10)を見ている。箔で包装した後の蓄電池への接触のための2つのコンタクトスタッド(9)がわきから引き出されている。
蓄電池をプラスチックで被覆されたアルミニウム箔中に、導電体の電気接点を外に引き出すことができるように入れた。水分不含の保護ガス雰囲気下で、引き続き、市販の導電性塩溶液LP30を貼り合わされた箔複合材中に吸引によって導入した。次にこの袋を密閉した。
