Description
(a)セルを、100%の充電状態に到達するまで充電する工程、
(b)当該セルを、開回路で少なくとも48時間の期間、100%の充電状態で保管する工程、
(c)充電及び保管中に発生したガスを除去する工程。
まずセルが電解質の注入(100)によって活性化される。セル内で室温(23℃)での48時間の含浸(200)期間が後続する。100%の充電状態に到達するまで充電(300)された後、セルは開回路で4週間室温で保管(400)される。
(図2の曲線Bによれば0.6ml)。この観察はカソード/電解質界面が徐々に安定化していることを示している。
2.1ガス放出に関する結果
上述のように、図2は、本発明による製造方法の繰り返し回数に伴って、Liイオンバッテリセルによるガス放出の低下が進むことを示している。従って、100%の充電状態で室温で4週間の第1の保管(400)の後、曲線Aは、セルが1.4mlのガスを発生することを示す。
図3は、本発明による製造方法の繰り返し回数に伴い、自己放電の低下が進むことを示している。従って、第1の保管(400)の後、Liイオンバッテリセルの自己放電は29%と評価されている。
