Abstract:

Photo-oxidation catalysts and methods for cleaning a metal-based catalyst are disclosed. An exemplary catalyst system implementing a photo-oxidation catalyst may comprise a metal-based catalyst, and a photo-oxidation catalyst for cleaning the metal-based catalyst in the presence of light. The exposure to light enables the photo-oxidation catalyst to substantially oxidize absorbed contaminants and reduce accumulation of the contaminants on the metal-based catalyst. Applications are also disclosed.

US Classification:

429/231500, 423/592000

Abstract:

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.

Abstract:

A lithium metal thin-film battery composite structure is provided that includes a combination of a thin, stable, solid electrolyte layer [ such as Lipon, designed in use to be in contact with a lithium metal anode layer; and a rapid-deposit solid electrolyte layer [ such as LiAlFin contact with the thin, stable, solid electrolyte layer [. Batteries made up of or containing these structures are more efficient to produce than other lithium metal batteries that use only a single solid electrolyte. They are also more resistant to stress and strain than batteries made using layers of only the stable, solid electrolyte materials. Furthermore, lithium anode batteries as disclosed herein are useful as rechargeable batteries.
