Description
以下、実施例に基づいて本発明をより詳細に説明する。下記の実施例は本発明を例示するためのもので、本発明の範囲が下記の実施例によって限定されるものではない。
正極活物質はスピネルLiMn2O4を使用し、正極用導電材料はアセチレンブラックを使用し、負極活物質としては黒鉛を使用した。電解液は、ECとEMCを3:7の割合で適用した有機溶媒に1MのLiPF6塩を溶解させて使用した。正極バインダーとしては、PVDF(polyvinylidenefluoride)を、負極用バインダーとしてはSBR/CMC(styrene butadiene rubber/carboxy methyl cellulose)を使用し、パウチはアルミニウムでなったものを使用し、パウチの厚さは120μmであった。セパレーターとしてはポリエチレンセパレーターを使用した。
電池容量の70%まで初期充電することを除き、実施例1と同様な方法で電池を製造した。製造された電池に対し、フォーメーションの前と後の厚さ変化を測定し、その増加率を図1に示した。
電池容量の100%まで初期充電し、フォーメーションの際に満充電過程省略することを除き、実施例1と同様な方法で電池を製造した。製造された電池に対し、フォーメーションの前と後の厚さ変化を測定し、その増加率を図1に示した。
電池容量の10%までに初期充電することを除き、実施例1と同様な方法で電池を製造した。製造された電池に対し、フォーメーションの前と後の厚さ変化を測定し、その増加率を図1に示した。
添加剤としてVCを最終電解液を基準として3.0重量%添加したことを除き、実施例3と同様な方法で電池を製造した。製造された電池に対して55℃高温放置実験を実施し、2週ごとにASIを測定して経時によるASI変化を観察し、その結果を図2に示した。
