Title (EN) ELECTROLYTIC SOLUTION FOR NONAQUEOUS ELECTROLYTIC SOLUTION BATTERY, AND NONAQUEOUS ELECTROLYTIC SOLUTION BATTERY USING SAME
(FR) ÉLECTROLYTE POUR BATTERIE À ÉLECTROLYTE NON AQUEUX, ET BATTERIE À ÉLECTROLYTE NON AQUEUX METTANT EN ŒUVRE CELUI-CI

Abstract:
(EN) This electrolytic solution for a nonaqueous electrolytic solution battery comprises: (I) at least one type of silane compound represented by general formula (1); (II) at least one type of compound from cyclic sulfonic acid compounds and cyclic sulfate ester compounds; (III) a nonaqueous organic solvent; and (IV) a solute. The electrolytic solution can achieve, in a balanced manner, an improvement in high-temperature storage properties at 70°C or higher, and the effect of reducing the amount of gas produced during high-temperature storage. (In general formula (1), R1s each independently represent a group including a carbon-carbon unsaturated bond; R2s are each independently selected from a fluorine group or a C1-10 linear or C3-10 branched alkyl group, wherein the alkyl group may include a fluorine atom and/or an oxygen atom; and x is from 2 to 4.)
(FR) L’électrolyte pour batterie à électrolyte non aqueux de l’invention contient (I) au moins une sorte de composé silane représenté par la formule générale (1), (II) au moins un composé choisi parmi un composé acide sulfonique cyclique et un composé ester de sulfate cyclique, (III) un solvant organique non aqueux, et (IV) un soluté. Cet électrolyte permet de développer de manière équilibrée une amélioration des caractéristiques de stockage à haute température à 70°C ou plus, et des résultats de réduction de quantité gaz généré lors d’un stockage à haute température. [Dans la formule générale (1), chaque R1 représente indépendamment un groupe possédant une liaison insaturée carbone-carbone. Chaque R2 est choisi indépendamment parmi un groupe fluor, et un groupe alkyle à chaîne droite de 1 à 10 atomes de carbone ou ramifié de 3 à 10 atomes de carbone, ledit groupe alkyle pouvant posséder un atome de fluor ou un atome d’oxygène. x est compris entre 2 et 4.]
(JA) 本発明の非水電解液電池用電解液は、(I)下記一般式(1)で示される少なくとも1種のシラン化合物、(II)環状スルホン酸化合物及び環状硫酸エステル化合物からなる少なくとも1種、(III)非水有機溶媒、及び、(IV)溶質とを含む。該電解液は、70℃以上での高温貯蔵特性の向上、及び高温貯蔵時に発生したガス量の低減効果をバランスよく発揮することができる。 [一般式(1)中、R1はそれぞれ互いに独立して、炭素-炭素不飽和結合を有する基を表す。R2はそれぞれ互いに独立して、フッ素基、炭素数が1~10の直鎖あるいは炭素数が3~10の分岐状のアルキル基から選択され、前記アルキル基はフッ素原子及び/又は酸素原子を有していても良い。xは2~4である。]
