・活物質:層状リチウム・ニッケル・マンガン・コバルト含有酸化物 90重両部
・導電剤:カーボンブラック(粉状アセチレンブラック) 8重両部
・結着剤:PVDF 2重両部
活物質層の塗工時の混練溶媒:N−メチル−2−ピロリドン(NMP)
集電箔:20μm厚のアルミ箔
塗工時の目付量:15mg/cm2
以下の条件で作製した。
活物質層の固形分:
・活物質:天然黒鉛 98重両部
・結着剤:SBR 1重両部
・増粘剤:カルボキシメチルセルロース(CMC) 1重両部
活物質層の塗工時の混練溶媒:水
集電箔:10μm厚の銅箔
塗工時の目付量:15mg/cm2
以下の条件で作製した。なお,基材樹脂の融点および耐熱層の端面部の厚さは,各実施例および各比較例により,後述のように変更した。
基材(多孔質フィルム):
・樹脂の種類:ポリオレフィン系樹脂のうちのPEを選択した。
・幅:120mm
・厚さ:20μm
耐熱層:
・無機フィラー粒子の種類:前述のもののうちアルミナを選択した。
・バインダーの種類:前述のもののうちアクリル系を選択した。
・主面部の厚さ:片面当たり2μm
・塗工後の乾燥条件:60℃5分間
以下の条件とした。
電極体:扁平捲回型
電解液:
・溶媒:エチレンカーボネート,エチルメチルカーボネート,ジエチルカーボネートの非水混合液(混合比は体積比にて3:5:2)
・電解質:ヘキサフルオロリン酸リチウム(LiPF6)(濃度は1M)
電池ケース:
・タイプ:図5に示したような平板角形状のハードケースで,安全弁付きとした。

作製した電池を,環境温度25℃にて,5A(Cレートにて1Cに相当)の定電流で4.2Vまで充電し,5分間休止後に3.0Vまで放電した。その後5分間休止してから,CC−CV充電(4.1V,レート1C,0.01Cカット)およびCC−CV放電(3.0V,レート1C,0.01Cカット)により初期容量確認を行った。
各実施例および各比較例での使用樹脂の融点より高い200℃で収縮試験を行った。この試験は,電池ではなくセパレータ単体の状態で行った。具体的には,50mm×50mmのサイズに切り出したセパレータを,カプトンテープ(「カプトン」は登録商標)でガラス板に固定したものを供試体とした。この供試体を一旦200℃まで加熱し,その後最も収縮した部位の長さLを測定し,(L/50)×100を算出して維持率(%)とした。こうして算出した維持率が85%以上の供試体を合格とし,85%未満となった供試体を不合格とした。
この試験は当然,電池の形にしたものを供試体とした。4.2Vに充電した状態を出発状態とし,環境温度25℃にて,10Cのレートの充電電流でさらに充電した。そのときの電池の表面温度が,150℃に達した(不合格)か,達しなかった(合格)かにより合否判定した。
