Abstract[English]
The invention relates to a polymer comprising or essentially consisting of monomer units derived from 1,3-butadiene, acrylonitrile and optionally, methacrylic acid, wherein the weight content of monomer units derived from 1,3-butadiene is at most 65 wt.-%, relative to the total weight of the polymer. The polymer is useful for manufacturing a cathode for a battery cell. The invention further relates to a cathode of a battery cell comprising the polymer as well as to a composition comprising the polymer and γ-valerolactone.[French]
L'invention concerne un polymère contenant, ou comprenant essentiellement, des motifs monomères dérivés de 1,3-butadiène, d'acrylonitrile et éventuellement d'acide méthacrylique. La teneur en poids des motifs monomères dérivés du 1,3-butadiène est inférieure ou égale à 65 % en poids par rapport au poids total du polymère. Le polymère est utile pour fabriquer une cathode destinée à une cellule de batterie. L'invention concerne également une cathode d'une cellule de batterie contenant le polymère et une composition contenant le polymère et la γ-valérolactone.
