Abstract
Embodiments of the invention provide a lead-acid battery having a positive electrode, a negative electrode, and a separator positioned between the electrodes to electrically insulate the electrodes. Battery includes a nonwoven fiber mat positioned adjacent an electrode. Mat includes a mixture of first glass fibers having diameters between 8 μm to 13 μm and second glass fibers having diameters of at least 6 μm and a silane sizing. An acid resistant binder bonds the glass fibers to form mat. A wetting component is applied to increase the wettability such that mat exhibits an average water wick height of at least 1.0 cm after exposure to water for 10 minutes. A conductive material is disposed on a surface of mat such that when mat is adjacent an electrode, the conductive material contacts the electrode. An electrical resistance of less than 100,000 ohms per square enables electron flow about mat.
