Abstract: front page image
(EN)Provided is an electrolyte in which the process temperature of an aluminum precipitation/dissolution reaction can be reduced. Also provided is a secondary battery in which the electrolyte is used. The electrolyte comprises an aluminum salt, an alkylsulphone (R1-S(=O)2-R2, where R1 and R2 each represent an alkyl group), and a solvent (relative permittivity: 20 or less). The content of the solvent is from 30 mol% to less than 88 mol%, and the molar ratio (content of aluminum salt/content of alkylsulphone) is from 4/5 to less than 7/3.
(FR)L'invention concerne un électrolyte permettant de réduire la température du processus réactionnel de précipitation/dissolution de l'aluminium. L'invention concerne également une batterie secondaire utilisant l'électrolyte. L'électrolyte comprend un sel d'aluminium, une alkylsulfone (R1-S(=O)2-R2, où R1 et R2 représentent chacun un groupe alkyle), et un solvant (permittivité relative : 20 ou moins). La teneur en solvant est de 30 % en moles ou inférieure à 88 % en moles, et le rapport molaire (teneur en sel d'aluminium/teneur en alkylsulfone) est de 4/5 à moins de 7/3.
(JA)アルミニウムの析出溶解反応の進行温度を低下させることが可能な電解質およびそれを用いた二次電池を提供する。この電解質は、アルミニウム塩と共に、アルキルスルホン(R1-S(=O)2 -R2:R1およびR2はいずれもアルキル基を表す。)および溶媒(比誘電率は20以下)を含む。溶媒の含有量は、30mol%以上88mol%未満であると共に、モル比(アルミニウム塩の含有量/アルキルスルホンの含有量)は、4/5以上7/3未満である。
