Abstract: Glass-fiber mats for lead-acid batteries are described. The glass-fiber mats may include a plurality of glass fibers held together with a binder. The binder may be made from a binder composition that includes (i) an acid resistant polymer, and (ii) a hydrophilic agent. The hydrophilic agent increases the wettability of the glass-fiber mat such that the glass-fiber mat forms a contact angle with water or aqueous sulfuric acid solution of 70° or less. Also described are methods of making the glass-fiber mats that include applying a binder composition to the glass fibers, and including a hydrophilic agent in the glass fiber mat that increases the wettability of the mat. The hydrophilic agent may be added to the binder composition, applied to the glass-fiber mat, or both.
