ABSTRACT:
A multi-layered gas permeable separator for lead-acid maintenance-free batteries, particularly for sealed gas recombining type rechargeable lead-acid batteries, is disclosed. The outer separator layers, adapted to be positioned against the opposite polarity plates of the battery, are composed of ultrafine fibers particularly glass fibers of relatively high fiber surface area. A third layer is interposed between the outer layers and is comprised of ultrafine fibers particularly of fiber glass, but has a fiber surface area on an equivalent weight basis which is substantially less than that of at least one of the outer layers. High rate, low temperature discharge performance of the battery is enhanced.
