Abstract: A battery containing an alkaline electrolyte, having within a container, said electrolyte and two electrodes separated by a separator; said separator being made of a partially reticulated polyvinyl acetal produced by the action of at least one aldehyde on polyvinyl alcohol; preferably an aromatic aldehyde, which may also have at least one hydroxyl radical, being used together with formaldehyde.

Abstract: In this invention, according to a first embodiment, the collector part of the electrode is formed by a full plate on which are deposited longitudinal strips of polytetrafluorethylene before the depositing of the electrochemically active part. In a second embodiment, the collector part is formed by a grid which is coated, before the depositing of the electrochemically active part, with a zinc oxide paste and polytetrafluorethylene In this way, one or more spaces are provided between the collector part and the electrochemically active part, the result thus being that the gases given off by the reactional process may escape easily by following the space(s), thus avoiding any deformation of the electrode.

Abstract: A Cd-Ni cell and its separator prepd. by (A) dissolving polyvinyl alcohol in crater adding an aldehyde to transform the alcohol to acetal, an acidifying cpd. and an anti-oxidant, the wt. of which is 0.5-2% of that of the polyvinyl alcohol, (B) forming a membrane with soln. from (A) and allowing to dry, (C) heating the membrane in a non-oxidising atmos. at 120-250 degrees C and (D) impregnating the membrane with water, as in parent patent, is improved in that an alkali sulphate esp. NaSO4 is incorporated in stage (A) in an amt. 1-5, pref. 3% of the wt. of polyvinyl alcohol. The sulphate increases the life of the separator. The cell is a reversible electrochemical generator and the separator has excellent selectivity w.r.t. O2 and low electrical resistance.
