Abstract
According to one embodiment, a plate or electrode for a lead-acid battery includes a grid of lead alloy material, a paste of active material applied to the grid of lead alloy material, and a nonwoven fiber mat disposed at least partially within the paste of active material. The nonwoven fiber mat includes a plurality of fibers, a binder material that couples the plurality of fibers together, and a conductive material disposed at least partially within the nonwoven fiber mat so as to contact the paste of active material. In some embodiments, the nonwoven fiber mat may have an electrical resistant of less than about 100,000 ohms per square to enable electron flow on a surface of the nonwoven fiber mat.
