摘要:
A separator for a lead-acid battery enabling the lead acid battery to infallibly have a predetermined capacity after the initial charging and a prolonged service life by limiting the maximum quantity of reducing substance liberated or produced from the separator at or below a given level.The separator for a lead-acid battery comprising a porous membrane made mainly from a polyolefin resin, an inorganic powder and a mineral oil and containing a surface active agent as an auxiliary material, characterized in that the amount of any reducing substance liberated or eluted after 24 hours of electrolysis carried out at about 25° C. with a direct current of 1.2 A by using an electrolytic cell composed of the porous membrane, a positive electrode, a negative electrode and diluted sulfuric acid is 1.0 ml or less per 100 cm2 when calculated from the consumption of a (1/100)N potassium permanganate solution per 100 cm2 of the porous membrane.

摘要:
A separator for a valve regulated lead-acid battery which comprises a paper sheet where very fine glass fiber is a main component, which has a piercing strength (puncture strength) of 4.5 N/mm or more and a tensile strength of 7.0 N/10 mm2 or more. The paper sheet is made by blending 80 to 90% by weight of glass fiber having 1.5 μm or less average fiber size, 5 to 10% by weight of single-material monofilament-form thermally non-adhesive organic fiber (non-heat-bondable organic fiber) and 5 to 10% by weight of single-material monofilament-form thermally adhesive organic fiber (heat-bondable organic fiber) comprising the same kind of material as in the thermally non-adhesive organic fiber in a wet papermaking process whereupon the fiber materials are bonded each other by thermal fusion of the thermally adhesive organic fiber whereby a coat (film) by melting of the organic fiber is not substantially formed on the surface of the glass fiber.

摘要:
A separator for a lead-acid battery, a pasting paper for a lead-acid battery, a plate for a lead-acid battery, and a lead-acid battery using the same are disclosed. The separator comprises a microporous sheet containing a heavy metal adsorbent comprising a rare earth compound having high heavy metal adsorbability in a neutral region and low heavy metal adsorbability in an acidic region, wherein the heavy metal adsorbent is unevenly distributed in a thickness direction of the sheet, thereby forming the heavy metal adsorbent-containing layer extending in a horizontal direction of the sheet and a layer which does not substantially contain the heavy metal adsorbent.
