Li1+a[Ni1−x−y−zCoxMnyMz]1−aO2
LiCoO2、カーボンブラック、PVDFバインダーを95:2.5:2.5の割合(重量比)でN‐メチルピロリドン溶媒中に混合して正極活物質層形成用組成物を製造し、それをアルミニウム集電体の一面に塗布した。その後、130℃で乾燥後、圧延密度3.53g/ccで圧延して正極を製造した。この際、集電体上に形成された正極活物質層は3.53g/cc、厚さ61μmであり、空隙率(porosity)は25%であった。
犠牲塩溶液に正極を浸漬してから乾燥する過程を3回繰り返したことを除き、実施例1と同様に行って正極を製造した。
犠牲塩溶液に浸漬および乾燥する過程を行わなかったことを除き、実施例1と同様に行って正極を製造した。
実施例1の正極活物質形成用組成物に、LiCoO2:LiN3の重量比が98:2となるようにアジ化リチウム(LiN3)を混合し、それをアルミニウム集電体の一面に塗布した後、130℃で乾燥後、電極密度3.53g/ccで圧延して正極を製造した。
実施例1の正極活物質形成用組成物に、LiCoO2:LiN3の重量比が98:2となるようにアジ化リチウム(LiN3)を混合し、130℃で乾燥後、電極密度3.6g/ccで圧延して正極を製造した。
実施例1、2および比較例1〜3で製造された正極の正極活物質層の密度、厚さ、および空隙率(porosity)を測定し、その結果を表1に示した。
実施例1、2および比較例1〜3で製造された正極を用いてコイン半電池(coin half cell)充放電実験を行って0.1C容量および効率を測定し、その結果を下記表2に示した。
放電条件:0.1C、CC(3.0V cut‐off)
