Abstract
Composition for the manufacture of composite electrodes usable in electrochemical devices and comprising at least: (i) one lithium insertion material; (ii) one electronic conducting material; (iii) one amino-functional cationic polyelectrolyte; (iv) water.
Claims25
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).
