Description
フッ酸はLiPF6等のフッ素を含有する支持塩の加水分解によって発生することが知られている。フッ酸の量はフッ酸トラップ剤によるフッ酸除去またはフッ酸添加により、フッ酸量を調整することができる。
(参考例1)
V2O5とLiOHとH3PO4をモル比およそ1:2:2とし、密閉容器中において160℃で8時間加熱し、得られたペーストを空気中600℃4時間焼成した。このようにして得られた粒子はβ型LiVOPO4であることがわかった。LiVOPO4粒子と、アセチレンブラックとを、90:10の重量比で秤量し、これに対して遊星型ボールミルによる1分間の混合処理をおこなったこれにより得た混合物とバインダーであるポリフッ化ビニリデン(PVDF)とを混合したものを、溶媒であるN−メチル−2−ピロリドン(NMP)中に分散させてスラリーを調製した。なお、スラリー中における混合物とPVDFとの重量比を90:10に調整した。このスラリーを集電体であるアルミニウム箔上に塗布し、乾燥させた後、圧延を行い、活物質層が形成された電極(正極)を得た。
正極と、負極とを、それらの間にポリエチレン微多孔膜から成るセパレータを挟んで積層し、積層体(素体)を得た。この積層体を、アルミラミネートパックに入れた。
電解液はエチレンカーボネート(EC)、ジエチルカーボネート(DEC)を体積比3:7で配合し、支持塩としてLiPF6を1mol/Lになるように溶解した。そこにフッ素を15ppmになるように添加した。
積層体を入れたアルミラミネートパックに、上記電解液を注入した後、真空シールし、参考例1の評価用セルを作製した。
評価用セルは0.1Cの電流値で3.6Vまで定電流定電圧充電をおこない、充電状態でのガス発生量を測定した。ガスの発生量の測定にはアルキメデス法を用いた。具体的にはセルを純水中に沈め、浮力を測定し、押しのけた水の体積からガス発生量を求めた。
Claims (1)
- 正極は、水熱合成法により合成されたLiVOPO 4 からなる活物質を含有し、電解液はフッ酸を10〜20ppm含有し、負極は炭素材料からなる活物質を含有し、前記負極はバナジウムを30〜80ppm含有するリチウムイオン二次電池。
