Abstract:
A method of automatic mass production and packaging of a plurality of single cell electrochemical devices which comprisesproviding a length of cathode coated current collector material with spaced terminals thereon,providing a length of first adhesive plastic tape with first release tape thereon,removing said first release tape,joining said first adhesive plastic tape to said cathode material in overlying relation,providing a length of insulating net,coating said net with liquid electrolyte,assembling said coated net, said cathode material and said first adhesive tape,curing said electrolyte coating,providing a length of anode material with spaced terminals thereon,cutting said length of anode material into anode leafs, with said terminals thereon,assembling said anode leafs onto said coated net in spaced and synchronized manner,providing a length of second adhesive plastic tape with second release tape thereon,removing said second release tape,joining together by pressure said cathode length, said first adhesive tape, said electrolyte coated net, said anode material leafs and said second adhesive tape into a layered assembly with said second adhesive tape in overlying relation, with said electrolyte coated net between said anode leafs and cathode length, and with said adhesive tapes on the outside of said cell, wherein said cathode length, said electrolyte coated net and said anode leafs are assembled in synchronized relation,cutting said layered assembly between said anode leafs to form individual cells, andstacking and packaging said cells.
