Abstract: A method for delaminating an electrode material of an electrode sheet from a current collector of the electrode sheet comprises positioning the electrode sheet in a sonicating bath, and at least partially within a target area of a sonotrode, wherein, in the target area, the distance between a front face of the sonotrode and the electrode sheet is less than or equal to 2 cm; and ultrasonically treating the electrode sheet, using the sonotrode, with a power density at the sonotrode front face greater than or equal to 50 W/cm2. An electrode material delaminating apparatus for performing the method is also disclosed.

Abstract: Ionic compounds having a freezing point of no more than 50° C., formed by the reaction of at least one amine salt of the formula R1R2R3R4N+X− (I) with at least one hydrated salt, which is a chloride, nitrate, sulphate or acetate of Li, Mg, Ca, Cr, Mn, Fe, Co, Ni, Cu, Zn, Cd, Pb, Bi, La or Ce; wherein R1, R2 and R3 are each independently a C1 to C5 alkyl or a C6 to C10 cycloalkyl group, or wherein R2 and R3 taken together represent a C4 to C10 alkylene group, thereby forming with the N atom of formula (I) a 5 to 11 membered heterocyclic ring, and wherein R4 is hydrogen, or phenyl, or C1 to C12 alkyl or cycloalkyl group, optionally substituted with at least one group selected from OH, Cl, Br, F, I, phenyl, NH2, CN, NO2, COOR5, CHO, COR5 and OR5, wherein R5 is a C1 to C10 alkyl or cycloalkyl group, and X− is an anion capable of being complexed by the said hydrated salt.
