Battery mounting apparatuses, electronic devices, and methods of forming electrical connections are described. In one implementation, a flexible circuit substrate has an area within which an electrical component, e.g. a thin-profile battery terminal housing member, is to be adhered. A conductive contact node pattern is disposed within the area and sized to be conductively adhered with the component. In one aspect, the conductive contact node pattern comprises an outer conductive node on the substrate at least a portion of which is positioned within the outermost 25% of the area. An electrical component is conductively bonded with the contact node pattern and encapsulating material is provided over and underneath the component. In a preferred aspect, the substrate and electrical component are vacuum processed sufficiently to redistribute the encapsulating material under the component. The positioning of the contact node pattern provides sufficient support during vacuum processing such that any tendency of the substrate to become lodged against the component is reduced, if not eliminated.

A button-type battery has an anode, a cathode, and an electrolyte encased with two terminal housing members. The terminal housing members have respective peripheries that are crimped together to form a fluid-tight seal. An insulating gasket is provided between the peripheries to electrically insulate the two terminal housing members. A porous separator physically separates the anode and cathode and extends between the terminal housing member peripheries at least partially into the fluid-tight seal. According to one aspect, the separator overlaps the gasket in the seal. According to another aspect, the separator and gasket are formed of a single, integral piece of material.

An enclosed electrical circuit and method for manufacturing the electrical circuit are provided. Initially a flexible substrate is formed with a plurality of electrical circuits. By way of example, each circuit can contain a conductive trace, a battery and a die, all in electrical communication. During the manufacturing process, a barrier is placed on the substrate and a curable encapsulant is poured into a cavity formed by the barrier and the substrate to encapsulate each circuit. The barrier can be formed as a compartmentalized dam having a separate cavity for each circuit, as a perimeter dam having a single cavity, or as a spacer sheet having a separate cavity for each circuit formed by a pattern of cut outs. Following the encapsulation step, the electrical circuits can be singulated into separate encapsulated circuits.

In one aspect, a method of making a battery includes fusing an alkali metal onto a patterned conductive layer. In another aspect, a method of forming a battery includes: a) providing a cathode base which comprises: a first nonconductive surface; a first conductive layer superjacent the first nonconductive surface; the first conductive layer comprising a first area; and a cathode layer superjacent the first conductive layer leaving at least a portion of the first area exposed; b) providing an anode base which comprises: a second nonconductive surface; a second conductive layer superjacent the first nonconductive surface, the second conductive layer comprising a second area; and an anode layer superjacent the second conductive layer leaving at least a portion of the second area exposed, the anode layer comprising an alkali metal; and c) aligning and coupling the anode layer of the anode base with the cathode layer of the cathode base, wherein the aligning and coupling leaves at least a portion of the first area and at least a portion of the second area exposed for electrical connection. The invention also encompasses batteries formed by such methods.

摘要:
A container for a battery and a method for manufacturing such a container are provided. The container includes a housing; a cover adapted for attachment to the housing by crimping; and a gasket crimped to the cover and housing. One or more grooves are formed in the housing or cover or both. During assembly, the gasket is positioned between the cover and the housing, and a portion of the cover and a portion of the housing are crimped together causing the gasket to flow into and conform to the shape of the grooves. Placement of the gasket within the grooves increases the surface area of the resultant seal thereby improving the seal quality without significantly increasing the thickness of the battery or cell. In addition the grooves prevent the gasket from flowing out of the crimped seam and help to maintain the crimp pressure throughout the lifetime of the battery.
