Patent ID: 8475962

Claim:
A combination comprising an aqueous suspension A and a composition B, wherein the aqueous suspension A comprises: one of the two materials selected from: (i) lithium insertion materials, (ii) an electronic conductor, and (iii) at least one amino-functional cationic polyelectrolyte selected from polymers produced by the combination of monomers carrying functions selected from the group consisting of: aminal, oxime, nitrile, imine, primary amine, secondary amine, tertiary amine, pyridine, enamine, ynamine, hydrazone, amide, amino acid, amino ester, isocyanate, nitrene, carbamate, carbazate, hydrazine, oxasiridine, β-lactam, enamide, cyanhydrin, pyrimidine, hydropyrimidine, pyrazine, piperazine, imidazolidine, pyridazine, aziridine, azetidine, pyrrolidine, piperidine, oxazole, oxazoline, oxazolidine, oxazolidinone, imidazoles, pyrrole, carbamic acid, urea, imide, hydroxymic acid, triazole, and isooxazole, alone or in combination with nonionic monomers, the quantity of polyelectrolyte being between 1.10 −5 and 5% by weight of the quantity of material (i) or (ii) also present in A and in that the composition B, which may be in the form of a powder or in the form of an aqueous suspension, comprises the other material selected from (i) and (ii).
