Battery systems employing bipolar electrodes

Abstract

A bipolar system comprises a plurality of flexible, conductive electrode strips assembled into a stack with porous, flexible, insulating separator strips being interposed between adjacent electrode strips. Each electrode strip at the exterior of the stack is provided on its innermost surface with electrochemically active material, and the or each electrode strip in the interior of the stack is provided on each of its opposite major surfaces with electrochemically active material. Sealing means is provided around the ends and lowermost edges of the electrode strips. The stack of electrode strips and separator strips is folded into a serpentine configuration and then mounted in a generally rectangular battery box such that the serpentine configuration winds back and forth between opposite walls of the box with electrochemically active material of opposite polarity on an adjacent strip.
