Abstract: Thermotropic ionic liquid crystal molecules, comprising a so-called rigid part, a so-called flexible part bonded covalently, directly or via a spacer, to said rigid part, and one or more ionic groups bonded covalently to said rigid part. Said molecules can be used as electrolytes in an electrochemical device, in particular a lithium-ion battery.

Abstract: The present invention relates to thermotropic ionic liquid crystal molecules of general formula (I) With E1 and E2, which may be identical or different, representing, independently of one another, a linear, saturated and unsubstituted C10 to C14 hydrocarbon-based radical, Ax− representing a sulfonate anion or a sulfonylimide anion of formula —SO2—N−—SO2CyF2y+1 with y being an integer ranging from 0 to 2 and Cx+ a sodium, lithium or potassium ion, most particularly advantageous for their conductivity performance qualities as an electrolyte in particular for lithium batteries.
