Abstract:
1. A bipolar electrode assembly, comprising: a first non-conductive frame defining a first window, wherein the first frame is coupled to a second nonconductive frame defining a second window, being connected together by a continuous laser weld to create a seal therebetween; a lead foil disposed between and coupled to the first and second frames such that opposite first and second sides of the lead foil are accessible through the first and second windows, respectively; wherein at least one of the first and second non-conductive frames further comprises an enhanced adhesive comprising a viscosity modifier and a coupling agent, wherein the enhanced adhesive is positioned between the lead foil and the at least one of the first and second non-conductive frames; a first phantom grid coupled to a positive electrode material, wherein the first grid and the positive electrode material are positioned in the first window and are conductively coupled to the first side of the lead foil; and a second phantom grid coupled to a negative electrode material, wherein the second grid and the negative electrode material are positioned in the second window and are conductively coupled to the second side of the lead foil.
