Abstract
【解決手段】第3の結着剤として水溶性結着剤の一種であるカルボキシメチルセルロースをさらに用い、前記有機溶媒溶解性結着剤であるポリビニルピロリドンの溶媒としてジメチルホルムアミドを用いることにより、激しい層分離現象のために困難であった有機溶媒溶解性結着剤と水溶性結着剤との組み合わせを可能にする。

Description
しかしながら、このゲル状の電解液は、漏液性及び電解液枯渇の側面で有利ではあるものの、伝導度が低いために高率放電時に容量及び出力の低下が発生し、しかも極めて制限的な環境でしか作動しないために特定用途に限定して使用されている。
しかしながら、高分子を添加する方法の場合、その効果面で極めて制限的であり、水銀を添加する方法の場合、環境保全の面で極めて有害であるという問題がある。
しかしながら、これら技術による電池は、作動期間が極めて短いために、応用器機に適用することが現実的に無理である。また、可能であるとしても、電解液が腐食性であるために、機器損傷のおそれがある。さらに、電解液内での電解質の濃度と一定の大気中の相対湿度とが熱力学的に平衡を保つことから、大気の湿度変化に応じて電解液の出入りが行われ、電池性能を維持し難くなるという短所がある。
しかしながら、この場合、疎水性の導電剤との均一な混合が困難であり、電池の長期放置時あるいは放電中に電極が集電体から脱離してしまう現象が発生する。このような脆弱な電極耐久性は、特に機械的支持体のない薄型マンガン電池の性能を劣化させる主な原因の一つとされている。
有機溶媒溶解性結着剤は、ポリビニルピロリドン、ポリフッ化ビニリデン、ポリメタクリル酸メチル及びスチレンブチルゴムからなる群から選択される1種以上であることが好ましい。さらに、水溶性結着剤は、ポリビニルアルコール、ポリエチレンオキサイド、架橋結合されたポリエチレンオキサイド又は2−ヒドロキシエチルセルロースにカルボキシメチルセルロースを添加したものであることが好ましい。
また、本発明は、導電剤であるアセチレンブラックをボールミルに入れて1〜7日間粉砕し、それを105℃の乾燥炉で12時間以上1次乾燥させ、その後、真空乾燥機で1時間2次乾燥させ;
正極製造用正極合剤基準で、60〜98重量%の二酸化マンガンと、0.1〜20重量%の予め粉砕乾燥したアセチレンブラックとを混合した後、高速混合機で1〜24時間混合し;
合剤基準で0.01〜5重量%となるように水溶性結着剤を水溶媒に溶解させ、これに合剤基準で0.1〜5重量%となるように有機溶媒溶解性結着剤を混合して、結着剤溶液を調製し;
混合された二酸化マンガン及びアセチレンブラック粉末に、最終正極板基準で有機溶媒溶解性結着剤が0.1〜5重量%、水溶性結着剤が0.01〜5重量%となるように結着剤溶液を添加撹拌して、正極製造用正極合剤スラリーを調製し;
調製された正極合剤スラリーを、包装材用高分子フィルムの集電体上にドクターブレードで50〜300μmmの厚さに塗布し、それを60℃の乾燥炉で2時間以上乾燥させる;
ことを特徴とする超薄型マンガン電池用正極の製造方法である。
先ず、導電剤のアセチレンブラックをボールミルに入れて1〜7日間粉砕し、それを105℃の乾燥炉で12時間以上1次乾燥させ、その後、真空乾燥機で1時間2次乾燥させる。
下記のような組成及び方法に基づいて電極を作製し、これを用いて超薄型マンガン電池を組み立てた。
正極製造にあたり、多成分結着剤溶液の代わりに単一結着剤として、正極合剤基準で5重量%となるようにポリビニルアルコールを混合した以外は、実施例1と同様にして正極及び電池を作製した。
正極製造にあたり、多成分結着剤溶液の代わりに単一結着剤として、正極合剤基準で5重量%となるようにポリビニルピロリドンを混合した以外は、実施例1と同様にして正極及び電池を作製した。
正極製造にあたり、多成分結着剤溶液の代わりに単一結着剤として、正極合剤基準で5重量%となるようにポリエチレンオキサイドを混合した以外は、実施例1と同様にして正極及び電池を作製した。
実施例及び比較例から得られた電池を用いて、終止電圧までの電池容量を試験し、正極及び負極の製造時の合剤混合量に基づいて正極活物質の利用率を測定した。
