Abstract:
The present invention discloses an amorphous material comprising nickel oxide doped with tantalum that is an anodically coloring electrochromic martial. The material of the present invention is prepared in the form of an electrode (200) having a thin film (202) of an electrochromic material of the present invention residing on a transparent conductive film (203). The material of the present invention is also incorporated into an electrochromic device (100) as a thin film (102)in conjunction with a cathodically coloring prior art electrochromic material layer (104) such that the devices contain both anodically coloring (102) and cathodically coloring (104) layers. The materials of the electrochromic layers in these devices exhibit broadband optical complimentary behavior, ionic species complimentary behavior, and coloration efficiency complimentary behavior in their operation.

Abstract:
A reverse configuration, lithium thin film battery (300) having a buried lithium anode layer (305) and process for making the same. The present invention is formed from aprecursor composite structure (200) made by depositing electrolyte layer (204) onto substrate (201), followed by sequential deposition of cathode layer (203) and current collector (202) on the electrolyte layer. The precursor is subjected to an activation step, wherein a buried lithium anode layer (305) is formed via electroplating a lithium anode layer at the interface of substrate (201) and electrolyte film (204). The electroplating is accomplished by applying a current between anode current collector (201) and cathode current collector (202).
Abstract:
A thermally-activated exhaust treatment device, such as a catalytic converter (20), for vehicles includes a core having an inner housing (21) and a catalytic material (27, 27'). A jacket includes an outer housing (22) enclosing the inner housing (21) but characteristically not contacting the inner housing (21). The inner and outer housings (21, 22) includes walls (30, 31) forming a vacuum-drawn sealed insulation cavity (26) around the inner housing (21). A temperature-activated variable insulator device is positioned within the outer housing (22) and includes a hydrogen source (32) and controls for controlling the variable insulator device. A vacuum-maintenance device is incorporated into the insulation cavity (26), and includes a small container, getter material positioned in the container, a porous member allowing gas in the insulation cavity (26) to communicate with the getter material. A multi-layered radiation shield is positioned in the vacuum space and is loosely coupled to the inner housing (21). A vacuum detector includes a visible indicator of the vacuum in the insulation cavity (26).

Abstract:
A lithium metal thin-film battery composite structure is provided that includes a combination of a thin, stable, solid electrolyte layer [18] such as Upon, designed in use to be in contact with a lithium metal anode layer; and a rapid-deposit solid electrolyte layer [16] such as LiAIF 4 in contact with the thin, stable, solid electrolyte layer [18]. 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.
