Button-type battery constructions

Abstract

Thin-profile battery electrode connection members, button-type battery electrode connection members, thin-profile battery constructions, button-type battery constructions, and methods of establishing electrical connections with and between both thin-profile batteries and button-type batteries are described. In one implementation, an electrode connection member comprises an inner conductive surface, and outer peripheral conductive surface, and an intermediate conductive surface joined with and extending between the inner and outer surfaces. The connection member defines an internal volume which is sized to receive at least one thin-profile battery. In one aspect, the intermediate conductive surface tapers between the inner and outer surfaces. The taper enables more than one thin-profile battery to be mounted within the internal volume without the need for edge insulation material over one of the batteries to prevent grounding. The electrode connection member can be mounted on a substrate for providing a generally self-contained, space-conserving power source which can include more than one battery connected in a series electrical connection.
