ABSTRACT:
A lead-acid storage battery, in one aspect of this invention, comprises units of cells each having, between alternate fibrous structure and negative plate which are arranged in laminated fashion on each side of a positive plate which is coated on both surfaces with an anode active material, a separator comprised of a paper-like sheet having continuous micro-porous openings throughout the entire area thereof and containing at least 70% by weight of phenol resin fibers each having a diameter of 5 microns or less produced by melt-spinning and curing a novolak resin. A lead storage battery having such separators is of an improved cell capacity and output and a prolonged life span. In another aspect of the invention, the separators are such that said phenol resin fibers have at least 60% by mole of the phenolic hydroxyl groups of the resin capped. A battery employing these separators is of further improved duration and satisfactory cell capacity and output.
