The invention relates to materials for use as electrodes in an alkali-ion secondary (rechargeable) battery, particularly a lithium-ion battery. The invention provides transition-metal compounds having the ordered-olivineor the rhombohedral NASICON structure and the polyanion (PO)as at least one constituent for use as electrode material for alkali-ion rechargeable batteries.

Cathode materials for secondary (rechargeable) lithium batteries

The present invention is concerned with cross-linked sulfonated polymers, eventually perfluorinated, and their preparation process. When molded in the form of membranes, the polymers are useful in electrochemical cells, in a chlorine-sodium electrolysis process, as separator in an electrochemical preparation or organic and inorganic compounds, as separators between an aqueous phase and an organic phase, or as catalyst for Diels-Alder additions, Friedel-Craft reactions, aldol concentrations, cationic polymerisation, esterification, and acetal formation.

The invention relates to materials for use as electrodes in an alkali-ion secondary (rechargeable) battery, particularly a lithium-ion battery. The invention provides transition-metal compounds having the ordered-olivine, a modified olivine, or the rhombohedral NASICON structure and the polyanion (PO ) as at least one constituent for use as electrode material for alkali-ion rechargeable batteries.

The present invention concerns polymers obtained by anionic initiation and bearing functions that can be activated by cationic initiations that are not reactive in the presence of anionic polymerization initiators. The presence of such cationic initiation functions allow an efficient cross-linking of the polymer after moulding, particularly in the form of a thin film. It is thus possible to obtain polymers with well-defined properties in terms of molecular weight and cross-linking density. The polymers of the present invention are capable of dissolving ionic compounds inducing a conductivity for the preparation of solid electrolytes.
