| 摘要 |
A two-phase positive electrode material for a lithium battery in which particles of lithium-enriched layered oxide of formula Li1+x(MnaNibMc)1−xO2 are at least partially coated on the surface with a metal oxide of formula LiyVOz. Such a material is advantageously produced by mixing the lithium-enriched lamellar oxide with at least one precursor of the metal oxide in aqueous solution, followed by thermal treatment at a temperature no lower than 280° C. |
