A reverse configuration, lithium thin film battery ( ) having a buried lithium anode layer ( ) and process for making the same. The present invention is formed from a precursor composite structure ( ) made by depositing electrolyte layer ( ) onto substrate ( ), followed by sequential depositions of cathode layer ( ) and current collector ( ) on the electrolyte layer. The precursor is subjected to an activation step, wherein a buried lithium anode layer ( ) is formed via electroplating a lithium anode layer at the interface of substrate ( ) and electrolyte film ( ). The electroplating is accomplished by applying a current between anode current collector ( ) and cathode current collector ( ).

A method is disclosed of forming a vanadium oxide film on a substrate utilizing plasma enhanced chemical vapor deposition. The method includes positioning a substrate within a plasma reaction chamber and then forming a precursor gas comprised of a vanadium-containing chloride gas in an inert carrier gas. This precursor gas is then mixed with selected amounts of hydrogen and oxygen and directed into the reaction chamber. The amounts of precursor gas, oxygen and hydrogen are selected to optimize the final properties of the vanadium oxide film An rf plasma is generated within the reaction chamber to chemically react the precursor gas with the hydrogen and the oxygen to cause deposition of a vanadium oxide film on the substrate while the chamber deposition pressure is maintained at about one torr or less. Finally, the byproduct gases are removed from the plasma reaction chamber.

Thin-film vanadium oxide layer that is suitable for use as a cathode in a lithium ion battery or other electronic applications, such as ion insertion layers in electrochromic devices as well as other uses, is deposited by a plasma-enhanced chemical vapor deposition at room temperature at rates as high as 11 /sec. from a vanadium-containing precursor reacted with oxygen and hydrogen. The vanadium oxide-based cathode produced by a lower temperature process and at a high deposition rate, exhibits a high discharge capacity, a high energy density, and a negligible capacity fade fiom its second cycle to at least 2,900 cycles, thus providing enhanced cyclic stability and an improved component for rechargeable lithium-ion batteries and other electronic devices.
