耐熱性微粒子を、ベーマイト粉末に代えて架橋アクリル樹脂微粒子(平均粒径0.4μm):4000gとした以外は、実施例3と同様にしてセパレータを作製した。このセパレータの耐熱多孔質層における耐熱性微粒子の体積比率は94体積%、耐熱多孔質層の空孔率は49%であった。
実施例2〜4のセパレータに用いたポリエチレン製多孔質膜のみを比較例1として用いた。
<正極の作製>
正極活物質であるLiCoO2:90質量部、導電助剤であるアセチレンブラック:7質量部、およびバインダであるPVDF:3質量部を、NMPを溶剤として均一になるように混合し、正極合剤含有ペーストを調製した。このペーストを集電体となる厚さ15μmのアルミニウム箔の両面に、活物質塗布長が表280mm、裏面210mmになるように間欠塗布し、乾燥した後、カレンダー処理を行って、全厚が150μmになるように正極活物質含有層の厚みを調整し、幅43mmになるように切断して正極を作製した。その後、正極におけるアルミニウム箔の露出部にタブ付けを行った。
負極活物質である黒鉛:95質量部とPVDF:5質量部とを、NMPを溶剤として均一になるように混合して負極合剤含有ペーストを調製した。このペーストを銅箔からなる厚さ10μmの集電体の両面に、活物質塗布長が表290mm、裏面230mmになるように間欠塗布し、乾燥した後、カレンダー処理を行って、全厚が142μmになるように負極活物質含有層の厚みを調整し、幅45mmになるように切断して負極を作製した。その後、負極における銅箔の露出部にタブ付けを行った。
前記のようにして得た正極と負極とを、実施例1のセパレータを樹脂多孔質膜が負極側に向くように介在させつつ重ね、渦巻状に巻回して巻回体電極群を作製した。得られた巻回体電極群を押しつぶして扁平状にし、厚み4mm、高さ50mm、幅34mmのアルミニウム製外装缶に入れ、電解液(エチレンカーボネートとエチルメチルカーボネートを体積比で1対2に混合した溶媒にLiPF6を濃度1.2mol/lで溶解したもの)を注入した後に封止を行って、非水電解質電池を作製した。
セパレータを実施例2〜4または比較例1のものに変更した以外は、実施例5と同様にして非水電解質電池を作製した。
