Description
項1. リチウム溶融塩を電解液に用いたリチウム二次電池であって、前記リチウム溶融塩は、Li[(FSO2)(CF3SO2)N]とLi[(FSO2)2N]を混合した混合塩の溶融塩である、リチウム二次電池。
項2. 前記混合塩が、モル比でLi[(FSO2)(CF3SO2)N]:Li[(FSO2)2N]=0.2〜0.8:0.8〜0.2である、項1に記載のリチウム二次電池。
粘弾性測定装置(TA instruments, AR-G2)を用いて乾燥空気フロー中でサンプルの粘度を測定した。
脱水雰囲気のドライチャンバー(ダイキン, HRG-50AR)内でサンプル中に導電率測定セル(Radiometer Analytical, CDC749)を導入し、インピーダンスアナライザ(東陽テクニカ, SI1260)用いた電気化学インピーダンス測定からサンプルの導電率を求めた。
アルゴン雰囲気のガス循環生成装置付グローブボックス(美和製作所, MDP-1.58-T1000, MP-H60W)内でセパレータに含浸させたサンプルをリチウム金属箔2枚と組み合わせて密閉し、二極式リチウム対称セルを作成した。このセルとポテンショスタット/ガルバノスタット(VMP3, Biologic)を用いた電気化学インピーダンス測定より溶液抵抗(Rs)と界面移動抵抗(Rct)を、クロノアンぺロメトリーより一定電圧(E)下における定常電流(I)を測定し、下式に従ってサンプルのリチウムイオン輸率(tLi)を求めた。
[数1]
tLi = Rs / (E/I - Rct)
公知の様々なリチウム塩の液相温度領域を測定した。結果を図1に示す。LiFTAの液相温度領域は100〜200℃、LiFSAの液相温度領域は139〜180℃であった。
Li[FTA]とLi[FSA]それぞれの単塩、それらを1:1のモル比で混合した混合塩(Li[(FSA)0.5(FTA)0.5])の粘度を測定した。結果を図2に示す。Li[FSA]はLi[FTA]よりも液相温度範囲は狭いが粘度は低い。それを添加したLi[(FSA)0.5(FTA)0.5]はLi[FTA]よりも粘度が低下し、また両単塩が凝固する100℃以下でも液体であることが分かった。
Li[FTA]とLi[FSA]それぞれの単塩、混合塩(Li[(FSA)0.5(FTA)0.5])のイオン導電率を測定した。結果を図3に示す。粘度とは逆にLi[(FSA)0.5(FTA)0.5]はLi[FTA]よりも高い導電率を発揮することが明らかになった。
Li[(FSA)0.5(FTA)0.5]を電解液としてセパレータに含浸させ、LiFePO4合材正極(LiFePO4:AB:PVDF = 84:8:8 wt%)、リチウム金属と組み合わせた電池試験ハーフセル(Li/Li[(FSA)0.5(FTA)0.5]/LiFePO4)を作製し、0.1 Cで充放電試験を行った。結果を図4に示す。室温域(35℃)から110℃まで安定に充放電することを確認した。特に45℃以上ではLiFePO4の理論容量(150 mAh・g−1)に近い放電容量を示した。
AB: アセチレンブラック
PVDF:ポリビニリデンフルオライド
Li/Li[(FSA)0.5(FTA)0.5]/LiFePO4電池セルで充放電速度を変えてレート試験を行った。結果を図5に示す。有機電解液(エチレンカーボネート(EC)とジメチルカーボネート(DMC)混合溶媒にLi[PF6]を濃度1 mol・dm−3添加)の結果と比較したところ、65〜110℃溶融塩のレート特性は室温(25℃)の有機電解液よりも高く、同温度(65℃)で比較しても同等であった。
Li/Li[(FSA)0.5(FTA)0.5]/LiFePO4電池セルで充放電サイクル試験を行った。結果を図6に示す。80℃の1 C充放電を70回繰り返したところ、140 mAh・g−1以上の放電容量を維持し、各サイクルのクーロン効率は初回を除き99.8%以上であった。
Li[(FSA)0.5(FTA)0.5]をLiCoO2合材正極(LiCoO2:AB:PVDF = 86:7:7 wt%)及びリチウム金属の対極と組み合わせたハーフセルで0.1C充放電試験を行った。結果を図7に示す。65〜110℃でLiFePO4の場合と同様に安定かつ高容量の充放電を確認した。
Li[(FSA)0.5(FTA)0.5]を炭素負極(炭素:PVDF = 95:5 wt%)及びリチウム金属の対極と組み合わせたハーフセルで0.1C充放電試験を行った。結果を図8に示す。80℃で正極と同様の安定かつ理論値(300 mAh・g−1)に近い容量で充放電を確認した。
低融点アルカリ金属溶融塩における輸送特性を比較した。Li0.4Cs0.6[FTA]は、Li[FTA]と Cs[FTA]をモル比で0.4:0.6の比率で混合することにより作製し、粘度、イオン導電率、リチウムイオン輸率は、上記のように測定し、リチウムイオン導電率は、イオン導電率とリチウムイオン輸率をかけ算することにより算出した。結果を表1に示す。
