  • Method for preparing solid solution materials such as lithium manganese oxide
    Patent number: 5961950
    Abstract: Lithiated manganese oxides are synthesized using a novel two stage process. Using appropriate starting materials, lithiation is accomplished via low temperature ion exchange in aqueous warm salt solution. A drying stage follows which completes the synthesis. Materials suitable for use as cathodes in lithium ion rechargeable batteries have been prepared in this way. Other solid solution transition metal materials might also be prepared using a similar low temperature ion exchange process.
