Abstract
An alkaline storage battery comprising at least one positive electrode and a negative zinc electrode in contact with an electrolyte via at least one electrolyte-impregnated separator is disclosed. The electrodes are clamped against two respective bipolar screens supported by a sealing frame. The positive electrode is in contact with a first electrolyte having a predetermined volume and composition via at least one first separator, the negative electrode is in contact with a second electrolyte having a predetermined volume and composition different from those of the first electrolytes via at least one second separator, and the first and second electrolytes are separated by a membrane forming a zincate and optionally aluminate filter, particularly an anionically conductive membrane defining first and second compartments.
