Title (EN) NONAQUEOUS ELECTROLYTE SOLUTION AND ELECTROCHEMICAL ENERGY STORAGE DEVICE USING SAME
(FR) SOLUTION ÉLECTROLYTIQUE NON AQUEUSE ET DISPOSITIF DE STOCKAGE D’ÉNERGIE ÉLECTROCHIMIQUE L’UTILISANT
(JA) 非水電解液およびそれを用いた電気化学エネルギー蓄積デバイス
Abstract:
(EN) Disclosed is a nonaqueous electrolyte solution containing a lithium salt (A), a quaternary ammonium salt (B) containing a straight chain alkyl group having 4 or less carbon atoms, and a solvent (C) composed of at least one compound selected from the group consisting of ethylene carbonates, propylene carbonates, butylene carbonates, ϝ-butyrolactones, dimethyl carbonates, ethyl methyl carbonates, diethyl carbonates, dimethoxyethanes, ethoxymethoxy ethanes and diethoxyethanes. The molar ratio of the solvent (C) to the lithium salt (A) C/A or the molar ratio of the solvent (C) to the ammonium salt (B) C/B is not more than 6, and the nonaqueous electrolyte solution is composed of a single phase. Consequently, there can be obtained a nonaqueous electrolyte solution of high ion concentration having excellent oxidation resistance and reduction resistance.
(FR) La présente invention concerne une solution électrolytique non aqueuse contenant un sel de lithium (A), un sel d’ammonium quaternaire (B) contenant un groupe alkyle à chaîne droite comportant 4 atomes de carbone ou moins et un solvant (C) composé d’au moins un composé sélectionné parmi des carbonates d’éthylène, des carbonates de propylène, des carbonates de butylène, des ϝ-butyrolactones, des carbonates diméthyliques, des éthylméthylcarbonates, des carbonates diéthyliques, des diméthoxyéthanes, des éthoxyméthoxyéthanes et des diéthoxyéthanes. Le rapport molaire du solvant (C) au sel de lithium (A) C/A ou le rapport molaire du solvant (C) au sel d’ammonium (B) C/B n’est pas supérieur à 6 et la solution électrolytique non aqueuse est composée d’une phase unique. En conséquence, on peut obtenir une solution électrolytique non aqueuse de concentration ionique élevée ayant une excellente résistance à l’oxydation et une excellente résistance à la réduction.
(JA)  本発明の非水電解液は、リチウム塩(A)と、炭素数が4以下の直鎖状アルキル基を含む第4級アンモニウム塩(B)と、エチレンカーボネート、プロピレンカーボネート、ブチレンカーボネート、γ-ブチロラクトン、ジメチルカーボネート、エチルメチルカーボネート、ジエチルカーボネート、ジメトキシエタン、エトキシメトキシエタン、およびジエトキシエタンからなる群より選択された少なくとも1種の化合物からなる溶媒(C)とを含む。リチウム塩(A)に対する溶媒(C)のモル比C/A、またはアンモニウム塩(B)に対する溶媒(C)のモル比C/Bが6以下であり、非水電解液は単一の相からなる。 これにより、優れた耐酸化性および耐還元性を有する、高イオン濃度の非水電解液が得られる。
