This specification discloses a thin-film gas diffusion electrode (GDE) and the method for making the same. The thin-film GDE is formed in a unitary way. A dual-nature porous thin film is used as the substrate. A surface processing is performed to make one surface of the thing film hydrophlic while the other surface hydrophobic. The hydrophlic area serves as the active layer for electrochemical reactions after chemical processing. The hydrophobic area is kept dry to form a smooth gas channel, functioning as a gas diffusion layer. In this method, the thin-film GDE is free from the use of binders and high-temperature high-pressure manufacturing processes.

Thin-film gas diffusion electrode and the method for making the same

A method for fabricating cylindrical and prismatic rechargeable metal-air batteries is devised. The method includes using micro fans to control air flowing through the batteries via air pathways between the packs of electrodes and separator sheet. The air pathways are created by protrusions printed or molded on plastic spacer film. The air is used by the positive electrode for generating electricity when the metal-air battery is discharged. By conjunction of a second positive electrode and an energy storage device, the micro fans can be actuated as soon as the metal-air battery is demanded by a load. The in-cell air management can not only supply air for reactions but also shut the system to preserve materials when they are not in service.

This invention provides a method for making an electrode film for a composite polymer material. A composite plating method is used to form a conductive plate film with microrough surface of 0.01 to 100 microns which will be adhered to a composite polymer material, enhances the adhering performance and reduces the interface electrical resistance.

The present invention is related to a method for manufacturing lead frames and a lead frame material including an intermediate layer and a top layer. The intermediate layer is composed of a layer of nickel-cobalt alloy having 5 to 30 wt. % of cobalt and a thickness of 3 to 20 microinches and a layer of nickel or nickel alloy having a thickness of 10 to 80 microinches. The intermediate layer can inhibit the diffusion of the base metal to the surface of the leads. The top layer consisting of gold or gold alloy, which is composed of gold and at least one metal selected from the group consisting of palladium, silver, tin and copper and has at least 60 weight percent gold, has a thickness of 0.1 to 5 microinches.

The present invention provides a porous electrode used for a conductive material-filled polymer composite. At least one surface of the porous electrode is an open porous structure, which includes a plurality of macropores and micropores randomly distributed and interconnected with each other. The conductive material-filled polymer composite includes a polymer substrate and conductive particles filled therein. When the surface of the open porous structure of the porous electrode is bonded with the conductive material-filled polymer composite, the conductive particles in the conductive material-filled polymer composite can be trapped in the macropores of the porous structure, and the polymer substrate in the conductive material-filled polymer composite can be immersed into the micropores of the porous structure. This enables a better direct contact between the conductive particles and the porous electrode. There is good adhesion strength between the porous electrode and the conductive material-filled polymer composite, and the interfacial resistance is decreased.
