Description
Sample#1の場合、基本的なリチウム硫黄バッテリー用の正極製作方法で、アルミホイルの上に均一に混合された正極スラリー(導電材、硫黄、バインダー、溶媒)をコーティングした後、乾燥させて製作する。
Sample#1の場合、sampleの中で最も低い硫黄ローディング量である6.4mg/cm2であるにもかかわらず、炭素構造層がなくて電解質を效果的に補液することができず、硫黄の反応面積が不十分なので、低い放電電圧と用量を表した。したがって、硫黄ローディング量8.0mg/cm2以上の電極では、もっと低い電圧と用量を表すのであろう。
20:硫黄正極(硫黄+導電材+バインダー)
30:アルミホイル
40:炭素構造層
50:硫黄含浸された炭素構造層
60:炭素コーティング層
