Abstract[English]
A composition comprising a non-spherical powderous cross-linked polymer obtained by grinding, wherein the cross-linked polymer comprises the monomer units 1,3 butadiene, (hydroxyethyl)methacrylate and trimethylolpropane trimethacrylate, and the non-spherical powderous cross-linked polymer has a particle size D(90) of 180 – 450 µm. The compositionfurther comprises a silica anti-caking agent. The compositions are used as binders in anodes of a rechargeable battery.[French]
L'invention concerne une composition comprenant un polymère réticulé pulvérulent non sphérique obtenu par broyage, le polymère réticulé comprenant les motifs monomères 1,3 butadiène, (hydroxyéthyl)méthacrylate et triméthacrylate de triméthylolpropane, et le polymère réticulé pulvérulent non sphérique ayant une taille de particules D (90) comprise entre 180 à 450 µm. La composition comprend en outre un agent anti-agglomérant de silice. Les compositions sont utilisées comme liants dans des anodes d'une batterie rechargeable.
