NOVELTY - A bipolar electrode assembly, comprises: a first non-conductive frame defining a first window, where the first frame is coupled to a second non-conductive frame; 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; where at least one of the first and second non-conductive frames further comprises an enhanced adhesive comprising a viscosity modifier and a coupling agent; and a second phantom grid coupled to a negative electrode material.    USE - The bipolar electrode assembly is used in a valve regulated lead acid battery (claimed).    ADVANTAGE - The bipolar electrode assembly is economical, highly improved and can be manufactured easily at a low cost.    DETAILED DESCRIPTION - A bipolar electrode assembly, comprises: a first non-conductive frame defining a first window, where the first frame is coupled to a second non-conductive frame defining a second window; 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; where at least one of the first and second non-conductive frames further comprises an enhanced adhesive comprising a viscosity modifier and a coupling agent, where the enhanced adhesive is positioned between the lead foil and the of the first and second non-conductive frames; a first phantom grid coupled to a positive electrode material, where 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, where the second grid and the negative electrode material are positioned in the second window and arc conductively coupled to the second side of the lead foil. INDEPENDENT CLAIMS are:    (1) a lead acid battery bipole for use in a valve regulated lead acid battery, comprising a non-conductive phantom grid coupled to a material selected from positive active material, negative active material, and lead oxide paste, and where a weight ratio of the positive active material to the phantom grid, is equal or less than 050;    (2) a valve regulated lend acid battery, comprising a set of non-conductive phantom grids and having a metallic lead and/or metallic lead alloy content of less than or equal to 10 g/Ah in fully discharged condition and a specific energy content of at least 45 Wh/kg; and    (3) a method of manufacture of a bipolar electrode assembly, comprising: positioning a lead foil having opposite first and second sides between a first non-conductive frame defining a first window and a second non-conductive frame defining a second window; positioning an enhanced adhesive between the lead foil and at least one of the first and second non-conductive frames, where the enhanced adhesive comprises a viscosity modifier and a coupling agent; laser-welding or ultrasonic welding the first frame to the second frame such that the first and second sides of the lead foil are accessible through the first and second windows, respectively; coupling a first phantom grid to a positive electrode material, and positioning the first grid and the positive electrode material in the first window to conductively couple the positive electrode material to the first side of the lead foil; and coupling a second phantom grid to a negative electrode material, and positioning the second grid and the negative electrode material in the second window to conductively couple the negative electrode material to the second side of the lead foil.
