Description
〔正極の作製〕初期放電容量が340mAh、粒度(D50)が3.3μmとなるように正極活物質V2O5を合成した。この正極活物質を、バインダーとしてのPVdF3重量%および導電性粒子としてのケッチェンブラック2重量%と混合し、溶媒としてN-メチルピロリドン(NMP)を用いてスラリーにした。その後、スラリーを、正極集電体としての多孔質のAl箔上に、ドクターブレード法によって塗工した。スラリーは、片面当たりの合材密度が、2g/cm3となるように、均一に塗布して成型し、126×97mm四方に裁断して正極とした。
実施例において、リチウム極用セパレータとして、正負極用セパレータと同じポリオレフィン系微多孔膜を用いた以外は同様にして、電極積層ユニットを作製した後に、リチウムイオン二次電池を得た。リチウム極用セパレータについて、実施例1と同様にして厚さを測定したところ、厚さは25μmであった。また、得られたリチウムイオン二次電池について、実施例と同様にして、サイクル特性および負荷特性の評価を行った。結果を図3および図4に示す。なお、ポリオレフィン系微多孔膜は、不織布には該当しない。
