Description
コバルトのみがドープされた材料(即ちx=0)では、ホルムアルデヒド-レゾルシノールゾルゲル合成経路を使用して、一般式
実施例1による材料を、9kWのCu回転アノードを備えたリガク社製(RTM)SmartLabを利用して行う粉末X線回折(PXRD)で検査した。
実施例1による材料を、BioLogic社製VMP3及びMaccor社製4600シリーズのポテンショスタットで実施される定電流サイクルによって電気化学的に特性評価した。すべての試料を金属リチウムに対してステンレス鋼コイン型電池に取り付け、2~4.8Vvs.Li+/Li、50mAg-1の電流レートで100サイクル行った。使用した電解液はLP30(1:1w/wの比のEC:DMC中LiPF6の1M溶液)であった。
本発明に従う各々の材料の1つのペレットをEL-Cell社製PAT-Cell-Press(RTM)単セルに取り付けた。すべての試料を金属リチウムに対して取り付け、OCVから4.8Vvs.Li+/Liまでサイクルにかけた後50mAg-1の電流レートで2Vまで放電させた。使用した電解液はLP30(1:1w/wの比のEC:DMC中LiPF6の1M溶液)であった。このセルは特にヘッドスペース内の圧力変化を記録するように設計されており、次いでこれをカソードから放出されたガスのモルに関連付けることができた。セル内の圧力センサは、USBリンクを介してコンピュータにつながれているコントローラボックスを介して接続されていた。次にこれは、EL-Cell社(RTM)により提供されるDatalogger及びEC-Linkソフトウェアを介して記録された。データは電圧、電流、時間及び圧力として記録された。これらの値は理想気体の法則を組み合わせてサイクル中に放出されたガスのモル数を計算することができ、これを使用して周囲条件下で放出されたガスの体積を計算することができた。充電中の各々の材料の総ガス損失を計算して図7に等高線図を作成した。これは三元空間内に組成の関数としてガス損失を示す。
