Thin-profile battery circuits and constructions, button-type battery circuits and constructions

A button-type battery circuit comprising:

• a first button-type battery comprising can and lid terminal members;
• a second button-type battery comprising can and lid terminal members, the first and second button-type batteries being conductively bonded in a stack;
• one of the first and second battery lid being conductively bonded to a first contact pad formed on a substrate;
• and
• the cans of both the first and second batteries being electrically coupled to a second contact pad formed on the substrate by a conductive adhesive disposed on the second contact pad.

A thin-profile battery circuit comprising at least two batteries connected in series, the circuit comprising:

• a substrate comprising an outer surface having a pair of spaced first and second electrical contact pads;
• a first thin-profile battery comprising a positive terminal and a negative terminal;
• a second thin-profile battery comprising a positive terminal and a negative terminal;
• a first electrical connection between a positive terminal of one of the first and second thin-profile batteries and a negative terminal of the other of the first and second thin-profile batteries, the first electrical connection comprising a first adhesive bond which connects the first and second batteries in a stack;
• a second electrical connection between the negative terminal of the one thin-profile battery and one of the first and second contact pads, the second electrical connection comprising a second adhesive bond;
• and
• a third electrical connection between the positive terminal of the other of the thin-profile batteries and the other of the first and second contact pads, the third electrical connection comprising a third adhesive bond.

A button-type battery circuit comprising:

• a substrate comprising an outer surface having a pair of spaced electrical contact pads;
• a first button-type battery comprising can and lid terminal housing members;
• a second button-type battery comprising can and lid terminal housing members;
• the first and second button-type batteries being conductively bonded to one another in a stack;
• one of the first and second battery can or lid being conductively bonded to one of the substrate outer surface contact pads;
• and
• the other of the first and second battery having one of its can or lid electrically connected to the other substrate outer surface contact pad and further comprising conductive adhesive disposed over a portion of the other substrate outer surface contact pad and connected with the cans of both batteries, wherein the first and second batteries comprise respective peripheral edges and further comprising an electrical insulator interposed between a portion of at least one of the peripheral edges and the other substrate outer surface contact pad.
