发明名称 Electrode for an Li ion battery having a polyether-siloxane copolymer as binder
摘要 An electrode comprises crosslinked polyether-siloxane copolymer obtained by crosslinking siloxane monomer (I), polyether macromers containing two or more alkenyl groups per molecule and optionally compound containing alkenyl groups, with polyethylene glycol functionalized with allyl group, as binder. An electrode comprises crosslinked polyether-siloxane copolymer obtained by crosslinking siloxane monomer of formula: H aR 1> bSiO ( 4 - a - b ) / 2 (I), polyether macromers containing two or more alkenyl groups per molecule and optionally compound containing alkenyl groups, with polyethylene glycol functionalized with allyl group, as binder. R 1> : monovalent, SiC-bonded 1-18C hydrocarbyl which is free of aliphatic C-C multiple bonds; a,b : non-negative integers; a+b : 0.5-3;and a : 0-2. (i) At least two silicon-bonded hydrogen atoms are present per molecule. An independent claim is included for preparation of crosslinked polyether-siloxane copolymer.
