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.
