ABSTRACT:
The invention provides lithiated molybdenum oxides useful as cathode (positive electrode) active materials in rechargeable batteries, especially in lithium ion rechargeable batteries. In one aspect, the invention provides lithiated molybdenum oxides, some of which can be represented by nominal formulas LixMoO2where x ranges from 0.1 to 2, and Li4Mo3O8. The crystal structure of the lithiated molybdenum oxides of the invention is characterized as being in a hexagonal space group with unit cell dimensions in a determined range. In a preferred embodiment, the lithiated molybdenum oxides of the invention can be formulated with known materials to provide electrodes for electrochemical cells. The invention also provides rechargeable batteries made by combining one or more such electrochemical cells.
