Abstract
Embodiments of the invention provide methods and apparatuses for enhancing electron flow within a battery, such as a lead-acid battery. In one embodiment, a battery separator may include a conductive surface or layer upon which electrons may flow. The battery separator may include a fiber mat that includes a plurality of electrically insulative fibers. The battery separator may be positioned between electrodes of the battery to electrically insulate the electrodes. The battery separator may also include a conductive material disposed on at least one surface of the fiber mat. The conductive material may contact an electrode of the battery and may have an electrical conductivity that enables electron flow on the surface of the fiber mat.
