摘要:
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.
摘要:
An electrochemical cell comprising a lithium anode and a fluorinated silver vanadium oxide cathode activated with a nonaqueous electrolyte is described. The fluorinated silver vanadium oxide is of the formula Ag4V2O11-xFx, wherein x ranges from about 0.02 to about 0.3.
