Title (EN) GEL ELECTROLYTE AND PREPARATION METHOD THEREOF
(FR) ÉLECTROLYTE DE GEL ET SON PROCÉDÉ DE PRÉPARATION
(JA) ゲル状電解質およびその調製方法
Abstract:
(EN) A gel electrolyte is provided which has a low matrix polymer concentration and which can maintain a gel state. This gel polymer contains a matrix polymer, and a nonaqueous electrolytic solution comprising a lithium-containing electrolyte dissolved in a non-aqueous solvent, wherein the matrix polymer is a copolymer including vinylidene fluoride units and fluorine atom-containing monomer units, and, for the concentration C (mass%) of the matrix polymer in the gel electrolyte, the melting temperature Tm of the matrix polymer satisfies the equation Tm ≧ 145 - C (I) (In expression (I), 0.1 ≦ C ≦ 30).
(FR) La présente invention concerne un électrolyte de gel qui a une faible concentration de polymère de matrice et qui peut maintenir un état de gel. Ce polymère de gel contient un polymère de matrice, et une solution électrolytique non aqueuse comprenant un électrolyte contenant du lithium dissous dans un solvant non aqueux, le polymère de matrice étant un copolymère comprenant des motifs de fluorure de vinylidène et des motifs de monomère contenant des atomes de fluor, et, pour la concentration C (% en masse) du polymère de matrice dans l'électrolyte de gel, la température de fusion Tm du polymère de matrice satisfait à l'équation Tm ≧ 145 - C (I) (Dans l'expression (I), 0,1 ≦ C ≦ 30).
(JA) マトリクスポリマーの濃度が低く、ゲル状態を維持できるゲル状電解質を提供する。リチウム含有電解質が非水溶媒に溶解している非水電解液と、マトリクスポリマーとを含むゲル状電解質であって、マトリクスポリマーは、フッ化ビニリデン単位とフッ素原子含有モノマー単位とを含む共重合体であり、マトリクスポリマーの融点Tは、ゲル状電解質におけるマトリクスポリマーの濃度C(質量%)に対して、 T≧145-C (I) (式(I)中、0.1≦C≦30である。) を満たす。
