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.

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: Method of determining at least one dynamic characteristic of a sample of a deformable solid or fluid material, comprising: the contacting of said sample (24, 42) with at least one interaction surface (23, 25, 41a, 41b); the application of a relative movement between said sample (24, 42) and said interaction surface (23, 25, 41a, 41b); and the measurement (26) of at least one dynamic or kinematic quantity in respect of the sample (24, 42) and/or said interaction surface (23, 25, 41a, 41b), wherein said interaction surface (23, 25, 41a, 41b) has an intrinsic wettability with respect to the material that is higher than that of metals. Device for implementing this method. According to particular embodiments, said interaction surface (23, 25) is made of high-density sintered ceramic or made of single crystal silicon or germanium, preferably having a zero open porosity and an arithmetic mean roughness parameter of less than 12.5 ?m and preferably between 0.4 and 1.6 ?m.
