NOVELTY - The bipolar battery assembly (700A) has a second rigid current collector which includes a surface having a second active material conductivity type. The second active material conductivity type corresponds to a battery electrode polarity opposite the first active material conductivity type. The first electrolyte region is defined at least in part by stackable casing frame, and first and second rigid current collectors. The compressible plastic seal, adhesive seal, metallized seal, melt seal, knife-edged seal, or welded seal, provides a liquid-tight enclosure for first electrolyte region.    USE - Bipolar battery assembly.    ADVANTAGE - Simplifies the battery assembly process since compressible plastic seal, adhesive seal, metallized seal, melt seal, knife-edged seal, or welded seal, provides a liquid-tight enclosure for first electrolyte region. Enhances conduction between the active material and the conductive silicon wafer since the conductive silicon wafer can include an ohmic contact layer, such as a metal silicide. Provides compatibility with an electrolyte in the electrolyte region since an adhesion layer. Produces an easily scalable architecture since the casings can include mating features. Enables the stress during impact to be shifted at least in part away from the current collector and transferred to the casing material due to the cup shape. Enables the current collectors to be made thinner or lighter in weight. Lowers the cost by reducing an amount of adhesive dispensed during fabrication. Reduces corrosion or erosion of the adhesive since the electrolyte cannot penetrate even when it manages to bypass the seals. Allows for thinner bi-plates and less weight in the battery by using fragile materials e.g., silicon wafers, to be used as bi-plates. Ensures that intimate contact is always maintained between the components since the adhesive seal can be placed between the plastic seal and the plastic casing frame. Enhances reliability due to the improved robustness of both the bi-plate-plastic seal and the plastic seal-plastic casing frame interfaces. Inhibits electrolyte from leaking into an environment surrounding the assembly by utilizing rings having weld joint.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for forming the bipolar battery assembly.    DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the assembled six-cell bipolar battery.    Bipolar battery assembly (700A)
