Abstract: Process for making a cathode comprising the following steps (a) Providing a cathode active material selected from layered lithium transition metal oxides, lithiated spinels, lithium transition metal phosphate with olivine structure, and lithium nickel-cobalt aluminum oxides, (b) treating said cathode active material with an oligomer bearing units according to general formula (I a), wherein R1 are the same or different and selected from hydrogen and C1-C4-alkyl, aryl, and C4-C7-cycloalkyl, R2 and R3 are selected independently at each occurrence from phenyl and C1-C8-alkyl, C4-C7-cycloalkyl, C1-C8-haloalkyl, OPR1(O)—*, and —(CR92)p—Si(R2)2—* wherein one or more non-vicinal CR92-groups may be replaced by oxygen, R9 is selected independently at each occurrence from H and C1-C4-alkyl, and p is a variable from zero to 6, and wherein the overall majority of R2 and R3 is selected from C1-C8-alkyl, and, optionally, at least one of carbon in electrically conductive form and, optionally, a binder, (c) appl
