  • Manganese oxide based materials as ion intercalation hosts in lithium batteries
    Publication number: 20050135993
    Abstract: The present invention is directed to a process for making an amorphous nanostructured cation-doped manganese oxide material useful as an ion intercalation host for rechargeable batteries, including the steps of preparing a solution containing cation permanganate combined optionally with a cation donor compound, mixing the solution with a reducing agent to yield a hydrogel comprising a manganese oxide compound, cryogenically freezing the hydrogel, drying the frozen gel to yield a cryogel amorphous nanostructured cation-doped manganese oxide, and heat treating the dried cryogel.
