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.sub.4).sup.3- as at least one constituent for use as electrode material for alkali-ion rechargeable batteries.

Вымысел относит к материалам для пользы как электроды в батарее алкали-iona вторичной (rechargeable), определенно батарее лити-iona. Вымысел обеспечивает смеси переход-metalla имея prikazyvat6-olivine, доработано olivine, или rhombohedral структура NASICON и polyanion (PO.sub.4).sup.3- как по крайней мере один состав для пользы как материал электрода для батарей алкали-iona rechargeable.
