気孔の平均大きさが400μmであり、気孔度が90%である銅フォームの集電体上にリチウムホイルを載せた後、ロールプレスによって前記銅フォームの気孔に挿入して電極複合体を製造した。この際、リチウム金属は、電極複合体の重量に対して5重量%となるようにした。その後、前記電極複合体上に5μm厚さのポリビニリデンフルオライド−ヘキサフルオロプロピレンのリチウムイオン伝導性保護膜を形成することで、負極を製造した。
(3)リチウム二次電池の製造
前記製造された正極と負極との間に、ポリプロピレン系多孔性膜を挟めた電極組立体をパウチ型の電池ケースに挿入した後、前記電池ケースに非水電解液(1M LiPF6、EC:EMC=3:7(体積比))を注入した上、完全に密封することでリチウム二次電池を製造した。
負極として、電極複合体の重量に対して10重量%のリチウム金属が含まれた電極複合体が適用された負極を用いたことを除いては、実施例1と同様の方法でリチウム二次電池を製造した。

負極として、電極複合体の重量に対して30重量%のリチウム金属が含まれた電極複合体が適用された負極を用いたことを除いては、実施例1と同様の方法でリチウム二次電池を製造した。
負極として、電極複合体の重量に対して50重量%のリチウム金属が含まれた電極複合体が適用された負極を用いたことを除いては、実施例1と同様の方法でリチウム二次電池を製造した。
負極として、リチウムイオン伝導性保護膜が形成されていない電極複合体のみを用いたことを除いては、実施例1と同様の方法でリチウム二次電池を製造した。
負極として、銅フォームではない一般の銅集電体に、リチウムホイルと、5μm厚さのポリビニリデンフルオライド−ヘキサフルオロプロピレンのリチウムイオン伝導性保護膜とが順次積層されたものを用いたことを除いては、実施例1と同様の方法でリチウム二次電池を製造した。
負極として、銅フォームではない一般の銅ホイル集電体にリチウムホイルが積層されたものを用いたことを除いては、実施例1と同様の方法でリチウム二次電池を製造した。
前記実施例及び比較例で製造されたリチウム二次電池に対し、0.1C電流密度の充電及び0.1C電流密度の放電を繰り返しながら、電池の短絡が起こる時点を測定し、下記の表1に示した。
