Abstract
A sintered bipolar battery plate (10) is made containing two porous electrodes and a central, non-porous, metallic cell separator-current collector sheet (12) where the positive electrode contains sintered particles (14) of elemental silver sintered into an expanded metal sheet (18) and the negative electrode contains sintered particles (16) of elemental iron sintered into an expanded metal sheet (18), where the positive and negative electrodes are sintered to a thin, porous, metallic connection layer (20) selected from at least one of nickel fiber or nickel powder, which is sintered to the current collector (12). This plate (10) can be placed in a case (22) containing alkali hydroxide electrolyte and having metal end plates (29) for electrical connections.
