Abstract:

A novel method for production of and an apparatus for an encapsulated solid-state electrochemical device is disclosed. The present invention provides for electrical devices, such as, for example, thin-film batteries with sensitive chemistries that can survive environmental exposure while providing external electrical contact to the internal cell chemistry. The method of packaging of the present invention may include bonding one or more protective multi-layer laminates to the environmentally sensitive surfaces of an electronic device. The present invention may provide the advantage of avoiding entrapped air beneath the laminates.

Infinite Power Solutions, Inc. - Littleton CO

International Classification:

H01M 6/40
H01M 6/42
H01M 6/46

US Classification:

429162, 429149, 429156

Abstract:

The present invention relates to apparatus, compositions and methods of fabricating high performance thin-film batteries on metallic substrates, polymeric substrates, or doped or undoped silicon substrates by fabricating an appropriate barrier layer composed, for example, of barrier sublayers between the substrate and the battery part of the present invention thereby separating these two parts chemically during the entire battery fabrication process as well as during any operation and storage of the electrochemical apparatus during its entire lifetime. In a preferred embodiment of the present invention thin-film batteries fabricated onto a thin, flexible stainless steel foil substrate using an appropriate barrier layer that is composed of barrier sublayers have uncompromised electrochemical performance compared to thin-film batteries fabricated onto ceramic substrates when using a 700 C. post-deposition anneal process for a LiCoOpositive cathode.

Assignee:

Infinite Power Solutions, Inc. - Littleton CO

International Classification:

B05D 1/32

US Classification:

427282, 427272

Abstract:

The present invention relates to masking techniques and apparatuses, and in particular, to a method and apparatus for masking a flexible substrate to be coated with one or more material layers. The method involves flexing a substrate to provide a curved surface and providing a flexible sheet on the curved surface to properly apply a coating on the surface of the substrate. The apparatus includes a substrate and a flexible sheet. An elastic material, such as a spring pin, or an off-axis roll-down bar may be used to create the tension used to flex the substrate and or flexible sheet.
