Abstract: Method of improving the performance of a Li-ion battery comprising metal-based cathode material which produces M2+ metal ions. The method comprises using a small organic compound in association with the electrolyte of the battery or using a polymer compound in association with the cathode active material of the battery. The small organic compound and the polymer compound comprise at least one chemical group suitable for forming complexes with the M2+ metal ions thereby preventing dissolution thereof.

Abstract: A copolymer including a monomer A with a molar ratio a varying between around 0.01 and around 0.20, a monomer B with a molar ratio b varying between around 0.2 and around 0.4, and a monomer C with a molar ratio c varying between around 0.50 and around 0.70, the monomer A being a hydrophilic monomer including a pendant chain of poly(ethylene oxide) (POE) with low molar weight, the monomer B being a hydrophobic monomer with a glass transition temperature (Tg) of around −30° C. or less, the monomer C being a monomer that is more hydrophobic than the monomer Band having a glass transition temperature (Tg) of around 80° C. or more, said monomers being organised in a hydrophilic segment, a hydrophobic segment and an intermediate segment located between the hydrophilic segment and the hydrophobic segment.

Abstract: This application describes an electrode material comprising an indigoid compound, i.e. indigo blue or a derivative thereof, for instance, together with particles of an electrochemically active material dispersed in a binder. Processes for the preparation of the electrode material and electrodes containing the material, as well as to the electrochemical cells and their use are also contemplated.

Abstract: This application describes an electrode material comprising particles of an electrochemically active material dispersed in a polymer binder, where the polymer binder is an acidic polymer or a mixture comprising a binder soluble in an aqueous solvent or a non-aqueous solvent (e.g. NMP) and an acidic polymer. The application also further relates to processes for the preparation of the electrode material and electrodes containing the material, as well as to the electrochemical cells and their use.

Abstract: Crosslinked polymers and their uses in electrochemical systems, for example, as electrolyte membrane, are described. More precisely, these crosslinked polymers are formed by the crosslinking of a random copolymer based on monomers of glycidyl methacrylate or acrylate and of poly(ethylene glycol) methyl acrylate or methacrylate with a volatile polyamine crosslinking agent.
