Methods for making solid-state laminate electrode assemblies include methods of forming a solid electrolyte interphase (SEI) by ion implanting nitrogen and/or phosphorous into the glass surface by ion implantation.

Treating sulfide glass surfaces and making solid state laminate electrode assemblies

Methods for making solid-state laminate electrode assemblies include methods to prevent devitrifying and damaging a lithium ion conducting sulfide glass substrate during thermal evaporation of lithium metal, as well as methods for making thin extruded lithium metal foils.

Solid-state laminate electrode assembly fabrication and making thin extruded lithium metal foils

A flexible metal-film laminate can comprise a layered film structure having a metal layer securely bonded to a film layer. The laminate contains a unique metal-oxide attachment structure between the film and metal layer comprising randomly distributed regions of metal-oxide. After the metal/metal-oxide layer, a chromium metal or chromium alloy layer is formed before subsequent layers of copper, gold, etc. The peel strength of such a laminate is significantly improved over prior laminates and is resistant to peel strength reduction due to environmental stress. The preferred metal-film laminates made with polyester or polyimide can be used in the manufacture of high-quality, low cost, flexible printed circuit boards.

Metal-film laminate resistant to delamination

A method for preparing a castable amorphous fluorocarbon coating upon the surface of a substrate which includes the steps of initially depositing a film of a fluorocarbon having a thickness between about 1500 .ANG. and 50,000 .ANG., and thereafter applying a second coating as a coverlay upon the initial film. Both the initial film and the castable coating consist of an amorphous fluorinated (ethylenic-cyclo oxyaliphatic substituted ethylenic) copolymer having the structural repeating unit: ##STR1## wherein 'm' and 'n' represent integers providing a molecular weight of between about 230,000 and 500,000, with the relative values of 'm' and 'n' providing a copolymer with a glass transition temperature ranging from between about 160.degree. C. and 240.degree. C.

Method of preparing adherent/coherent amorphous fluorocarbon coatings

A flexible metal-film laminate can comprise a layered film structure having a metal layer securely bonded to a film layer. The laminate contains a unique metal-oxide attachment structure between the film and metal layer comprising randomly distributed regions of metal-oxide. The peel strength of such a laminate is significantly improved over prior laminates and is resistant to peel strength reduction due to environmental stress.
