Abstract
【解決手段】スラリー組成物は、カルボキシメチルセルロース(CMC)、スチレンブタジエンゴム(SBR)、及びPVDFからなる。スラリーのpHを下げるためにポリアクリル酸(PAA)を使用することができる。スラリーは、スラリー中のCMC及びSBRを合わせた濃度が0.5〜30質量%のときに安定しており、10質量%では更に安定化する。
【選択図】なし
Description
グラファイト電極スラリーはCMC又はPAAを2%、SBRを5%、PVDFを3%、カーボンブラックを2%及びグラファイトを88%含んでなることができる。上記成分は水溶液中のスラリーと混合することができる。前記水溶液は脱イオン水でよい。安定な分散液中にPVDFを維持するためにラテックスを前記溶液に添加してもよい。使用された材料は市販のものである。他の材料は使用しない。水分量は、活性材料、バインダー及び他の導電性の材料、並びにスラリー中で使用されたそれらの濃度に依存する。
実施例2−カソード電極スラリー
それにもかかわらず、Li-NCO電極はNMP、水、アセトン、DMAC又は他の有機溶媒を使用することにより調製できる。
