Sulfide / polysulfide ionic liquid electrolyte for lithium-sulfur batteries

摘要

Comprising an ionic liquid comprising at least one lithium salt, at least one non-aqueous solvent, and a compound of formula I: M2Sy / M2 (Sm) y, M is an organic cation, m is an integer from 1 to 16, y relates to an electrolyte that is an integer indicating the stoichiometry necessary to neutralize the 2M positive charge. The invention also relates to a method for producing an electrolyte, a battery comprising it, and its use in electronic equipment, stationary applications, and transportation equipment.
