The purpose of the present invention is an electrode for an Li ion battery, which contains, as a binder, a crosslinked polyether-siloxane copolymer (V), which can be prepared by crosslinking siloxane macromers (S) having the chemical formula 1 by means of polyether macromers (P) containing at least two alkenyl groups per molecule and optionally further compounds (W) containing alkenyl groups, with polyethylene glycols functionalized by one allyl group being excepted from the compounds (W); and also a method for preparing a crosslinked polyether-siloxane copolymer (V) as a binder for the electrode of an Li ion battery in a crosslinking step. [Chemical formula 1] H_aR^1_bSiO_(4-a-b)/2 wherein R1 is a monovalent, SiC-bonded C1-C18 hydrocarbon radical that is free of aliphatic carbon-carbon multiple bonds and a and b are nonnegative integers, with the proviso that 0.5 < (a+b) < 3.0 and 0 < a < 2, and that at least two silicon-bonded hydrogen atoms are present per molecule. |
