  • Electrolytes for electrochemical generator
    Patent number: 11613520
    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.
    Type: Grant
