Description
まず、溶媒としてのTHF 300mlと塩としてCH3OK 30gとを約150℃で加熱して、塩を溶かした溶液を作った。次いで、PVdF 10gを前記溶液に入れ、約200℃で3〜5時間ほど攪拌しつつ合成を進めた。合成が完了した後、溶液をフィルタリングし、残りの反応物を100℃で乾燥して、溶媒及び有機物を除去した。最終合成物は、エタノール及び蒸留などで洗浄し、再び乾燥した。また、アニーリングを900〜1,000℃で進めて結晶性を高め、最終的に、陰極活物質を合成した。
前記製造例1で、PVdFの代わりに、それぞれPVC、PE、及びPPを使用したことを除いては、前記製造例1と同じ過程で実施して、陰極活物質を合成した。
前記製造例1で製造されたカルビン5gを結合剤であるポリ塩化ビニリデン(PVdF:(KF1100、日本・クレハ化学))5wt%のN−メチルピロリドン(NMP)溶液0.35gに混合してスラリーを製造した。前記スラリーをドクターブレードを使用して銅集電体上に約50μmの厚さに塗布し、常温で2時間乾燥した後、真空、120℃の条件で2時間間さらに乾燥して陰極板を製造した。
前記製造例1で製造されたカルビンの代わりに、前記製造例2で製造されたカルビンを使用したことを除いては、前記実施例1と同じ方法でコインセルを製造した。
陰極活物質として、前記製造例1で製造されたカルビン2.5gと共に、黒鉛(SFG6、TimCal社)2.5gを使用したことを除いては、前記実施例1と同じ方法でコインセルを製造した。
陰極活物質として、カルビンの代わりに、黒鉛(SFG6、TimCal社)5gのみを使用したことを除いては、前記実施例1と同じ方法でコインセルを製造した。
前記実施例1−3及び比較例1で製造されたリチウム電池に対して、陰極活物質1g当たり10〜20mAの電流で電圧が0.001V(vs.Li)に至るまで充電し、再び同じ電流で電圧が1.5V(vs.Li)に至るまで放電した。次いで、同じ電流及び電圧区間で充電及び放電を50回反復した。第1サイクルでの充放電結果を図7に示した。容量維持率は、下記数式1で定義される。実施例1−3及び比較例1の容量維持率を、表3に示した。
容量維持率[%]=第50サイクルでの放電容量/第2サイクルでの放電容量(数式1)
