Abstract
Thin-profile battery circuits and constructions, and in particular button-type battery circuits and constructions and methods of forming the same are described. In one implementation, a substrate is provided having an outer surface with a pair of spaced electrical contact pads thereon. At least two thin-profile batteries are conductively bonded together in a stack having a lowermost battery and an uppermost battery. The batteries include respective positive and negative terminals. The lowermost battery has one of its positive or negative terminals adhesively bonded to one of the pair of electrical contact pads while the uppermost battery has one of its positive or negative terminals electrically connected to the other of the pair of electrical contact pads. The batteries can be provided into parallel or series electrical connections.
