Abstract
Abstract A porous battery plate comprising nickel metal powder sintered to nickel metal mesh and having an electrochemically active material such as cadmium hydroxide impregnated therein is shown to be secured to a nickel lead member for use in electrically connecting the plate as an electrode in an alkaline electrolyte battery or the like by inserting a nickel-plated nickel wire between portions of the lead member and plate and by welding the lead member to the plate by electrical resistance welding, the nickel wire plating embodying a phosphor constituent or the like such as is inherently deposited therein during formation of the plating by electroless nickel-plating techniques for lowering the melting temperature of the nickel plating below the melting temperature of the nickel lead member, the plated nickel wire serving as a weld projection for securing the lead member to the plate.

Claim 4
Dependent Claim
31 words
The method as set forth in claim 1 wherein said wire embodies a nickel metal core coated with nickel metal material having a melting temperature lower than said electrode lead material.
Claim 5
Independent Claim
112 words
A method for forming a cadmium battery electrode comprising the steps of electroless nickel plating a nickel wire to form a wire coating of a nickel metal material having a phosphor constituent therein, arranging said wire in U-shape in a plane between a portion of a nickel metal strip and a portion of a battery plate so that substantial portion of the wire periphery is in contact with said strip and plate, said plate embodying a porous, sintered nickel plaque having electrochemically active cadmium material impregnated therein, and directing electrical current through the strip, wire and plate for resistance welding the wire to the strip and plate to form a battery electrode.
Claim 6
Independent Claim
110 words
A method for forming a nickel battery electrode comprising the steps of electroless nickel plating a nickel wire to form a wire coating of a nickel metal material having a Phosphor constituent therein, arranging said wire in U-shape between a portion of a nickel material strip and a portion of a battery plate so that a substantial portion of the wire periphery is in contact with said strip and plate, said plate embodying a porous, sintered nickel plaque having electrochemically active nickel material impregnated therein, and directing electrical current through the strip, wire and plate for resistance welding the wire to the strip and plate to form a battery electrode.
Claim 7
Dependent Claim
83 words
A battery electrode comprising a porous battery plate, a flat metal strip lead member, and a length of wire disposed in a plane between said lead and plate having a substantial portion of said wire in contact with said lead and plate, said wire having at least a surface layer of metal material which has a similar but slightly lower melting temperature than the melting temperature of the metal embodied in the lead member, said wire being welded to said lead and plate.
Claim 8
Dependent Claim
25 words
A battery electrode as set forth in claim 8 wherein said battery plate comprises a porous, sintered nickel plaque having electrochemically active material impregnated therein.
Claim 9
Dependent Claim
20 words
A battery electrode as set forth in claim 8 wherein said lead comprises a flat strip of nickel metal material.
Claim 10
Dependent Claim
32 words
A battery electrode as set forth in claim 8 wherein said wire comprises a nickel metal core coated with a nickel metal material having a melting temperature lower than said lead material.
Claim 11
Dependent Claim
84 words
A cadmium battery electrode comprising a porous sintered nickel plaque having electrochemically active cadmium material impregnated therein, a flat strip of nickel metal material having a portion superimposed on a portion of said plate, and a wire embodying a nickel metal core having an electroless nickel plated coating thereon, said wire being formed in U-shape and disposed in a plane between said superimposed strip and plate portions in contact with said strip and plate portions, said wire being welded to said strip and plate.
Claim 12
Dependent Claim
84 words
A nickel battery electrode comprising a porous sintered nickel plaque having electrochemically active nickel material impregnated therein, a flat strip of nickel metal material having a portion superimposed on a portion of said plate, and a wire embodying a nickel metal core having an electroless nickel plated coating thereon, said wire being formed in U-shape and disposed in a plane between said superimposed strip and plate portions in contact with said strip and plate portions, said wire being welded to said strip and plate.
