Description
例えば、第1分離膜と接触する第2ラミネータL2の上部ブロックより、第2分離膜/正極と接触する第2ラミネータL2の下部ブロックの温度を10〜30℃ほど高く維持し、不要な電力消耗を減らすことができる。
基本単位体に備えられる電極は正極又は負極に区別され、正極及び負極との間に分離膜を介在させた状態で相互結合させて製造される。正極は、例えば、正極集電体上に正極活物質、導電材及びバインダの混合物であるスラリーを塗布した後、乾燥及びプレッシングして製造され得、必要に応じては前記混合物に充填剤をさらに添加したりする。正極をロールに装着されるシート状に具現すれば、基本単位体の製造工程の速度を向上させることができる。
正極集電体は、一般的に3〜500μmの厚さに作製する。このような正極集電体の材料は、電池に化学的変化を誘発すること無く高い導電性を有するものであれば特に制限されるものではなく、例えば、ステンレススチール、アルミニウム、ニッケル、チタン、焼成炭素、又はアルミニウムやステンレススチールの表面にカーボン、ニッケル、チタン、銀などで表面処理したものなどが用いられ得る。正極集電体の表面に微細な凹凸を形成し、正極活物質の接着力を高めることもでき、フィルム、シート、ホイル、ネット、多孔質体、発泡体、不織布体など多様な形態が可能である。
正極活物質はリチウム二次電池の場合、例えば、リチウムコバルト酸化物(LiCoO2)、リチウムニッケル酸化物(LiNiO2)などの層状化合物や、1又はそれ以上の遷移金属に置換された化合物;化学式Li1+xMn2-xO4(ここで、xは0〜0.33である)、LiMnO3、LiMn2O3、LiMnO2などのリチウムマンガン酸化物;リチウム銅酸化物(Li2CuO2);LiV3O8、LiFe3O4、V2O5、Cu2V2O7などのバナジウム酸化物;化学式LiNi1-xMxO2(ここで、M=Co、Mn、Al、Cu、Fe、Mg、B又はGaであり、x=0.01〜0.3である)で表現されるNiサイト型リチウムニッケル酸化物;化学式LiMn2-xMxO2(ここで、M=Co、Ni、Fe、Cr、Zn又はTaで、x=0.01〜0.1である)又はLi2Mn3MO8(ここで、M=Fe、Co、Ni、Cu又はZnである)で表現されるリチウムマンガン複合酸化物;化学式のLiの一部がアルカリ土金属イオンに置換されたLiMn2O4;ジスルフィド化合物;Fe2(MoO4)3などを挙げることができるが、これらだけで限定されるものではない。
負極は、例えば、負極集電体上に負極活物質を塗布、乾燥及びプレッシングして製造され得、必要に応じて導電材、バインダ、充填剤などが選択的にさらに含まれ得る。負極をロールに装着されるシート状に具現すれば、基本単位体の製造工程の速度を向上させることができる。
負極集電体は、一般的に3〜500μmの厚さに作製される。このような負極集電体は、電池に化学的変化を誘発すること無く導電性を有するものであれば特に制限されるものではなく、例えば、銅、ステンレススチール、アルミニウム、ニッケル、チタン、焼成炭素、銅やステンレススチールの表面にカーボン、ニッケル、チタン、銀などで表面処理したもの、アルミニウム−カドミウム合金などが用いられ得る。また、正極集電体と同様に、表面に微細な凹凸を形成して負極活物質の結合力を強化させることもでき、フィルム、シート、ホイル、ネット、多孔質体、発泡体、不織布体などの多様な形態が可能である。
負極活物質は、例えば、難黒煙化炭素、黒煙系炭素などの炭素;LixFe2O3(0≦x≦1), LixWO2(0≦x≦1), SnxMe1-xMe’yOz (Me:Mn, Fe, Pb, Ge; Me’:Al、B、P、Si、周期律表の1族、2族、3族元素、ハロゲン;0<x≦1;1≦y≦3;1≦z≦8)などの金属複合酸化物;リチウム金属;リチウム合金;ケイ素系合金;錫系合金;SnO, SnO2, PbO, PbO2, Pb2O3, Pb3O4, Sb2O3, Sb2O4, Sb2O5, GeO, GeO2, Bi2O3, Bi2O4, and Bi2O5などの金属酸化物;ポリアセチレンなどの導電性高分子;Li-Co-Ni系材料などが用いられ得る。
分離膜は、フォールディング工程やロール(roll)工程とは関係なく、単純積層工程により基本単位体を形成して単純積層を具現することになる。特に、分離膜と電極の接着は、ラミネータの内部で圧力(又は圧力と熱)によって行われ得る。これにより、電極と分離膜シートとの間の安定的な界面接触が可能になる。
