    Abstract: The present invention provides an acidic aqueous composition for copper electroplating comprising (a) copper ions; (b) bromide ions; and (c) at least one additive of formula (S1) wherein XS1 is selected from a linear, branched or cyclic C1-C12 alkanediyl, which may be substituted or unsubstituted, and which may optionally be interrupted by O, S or NRS40; RS1 is a monovalent (a) poly(oxy(C3 to C6 )alkylene)-block-poly(oxyethylene) group which is bound to the N-atom by the poly(oxy(C3 to C6 )alkylene part, or (b) a poly(oxyethylene)-block-poly(oxy(C3 to C6)alkylene)-block-poly(oxyethylene), which both have a poly(oxyethylene) content of from 5 to 30 % by weight; RS2, RS3, RS4 (a) are selected from H, RS1, RS40, or (b) RS3 and an adjacent group RS4 or, if n>2, two adjacent groups RS4 may together form a divalent group XS3; RS40 is selected from (a) linear or branched C1-C20 alkyl, which may optionally be substituted by hydroxy, alkoxy or alkoxycarbonyl, and (b) linear or branched C1-C20 alkenyl, which may optionally be substituted by hydroxyl, alkoxy or alkoxycarbonyl; XS3 is selected from a linear, branched or cyclic C1-C12 alkanediyl, which may be substituted or unsubstituted, and which may optionally be interrupted by O, S or NRS40; and n is an integer of from 1 to 6.

    Abstract: Process for making a partially coated electrode active material wherein said process comprises the following steps:
    (a) formula Li 1+x TM 1-x O 2 , wherein TM contains at least 90 mol-% Ni, and x is in the range of from - 0.05 to 0.05,
    (b) treating said electrode active material with an alkoxide or amide of zirconium,
    (c) treating the material obtained in step (b) with moisture,
    (d) repeating the sequence of steps (b) and (c) four to twelve times,
    (e) performing a post-treatment by heating the material obtained after the last step (d) at a temperature from 250 to 750°C.
