Abstract
Electrical connection is maintained between an electrical conductor element (32) and a fragile expanded-metal grid current collector element (12) of a flexible laminate structure rechargeable battery (10) by means of thermally-activated adhesive sheet material (34) which provides physical reinforcement as well as maintaining stable electrically-conductive contact between the elements, Such adhesive materials comprising a metal foil surface (46) may also provide direct electrical connection between current collector or battery electrode elements and external utilization devices.
Claims14
A method of making an electrical connection between a pair of electrically-conductive elements
- characterized in that
- a) said conductive elements are placed in physical, electrically-conductive contact;
- and
- b) at least a portion of an adhesive element comprising a flexible substrate bearing a layer of adhesive composition is applied over a first of said conductive elements to adhesively engage said first element and at least a portion of the surface of the second of said elements which encompasses the area of said physical contact, thereby maintaining said physical contact.
A method of making an electrical connection to a battery structure comprising laminated polymeric electrode and separator/electrolyte members and having at least one electrically-conductive collector member outwardly exposed at the surface of an associated electrode member, said connection being made by fixed electrical contact between a conductor element and said collector member
- characterized in that
- a) said conductor element is placed in physical contact with said collector member;
- and
- b) at least a portion of an adhesive element comprising a flexible substrate bearing a layer of heat-activatable polymeric ionomer adhesive composition is applied over said conductor element to adhesively engage said conductor element and at least a portion of the surface of said collector member encompassing the area of said physical contact, thereby maintaining said physical contact.
A battery structure comprising laminated polymeric electrode and separator/electrolyte members, at least one electrically-conductive collector member having a surface disposed outwardly from an associated electrode member, and an electrical conductor member in fixed electrical contact with said collector member
- characterized in that
- a) said conductor member is in physical contact with said collector member;
- and
- b) said physical contact is maintained by an adhesive element comprising a flexible substrate bearing a layer of adhesive composition adhesively engaging said conductor member and at least a portion of the surface of said collector member encompassing the area of said physical contact.
