Abstract
A lead-acid battery in which the plates are fabricated from a paste containing principally lead oxide and a small amount of dimensionally isotropic graphite fiber of a specific type. The specific type of graphite fiber may be either a graphite fiber synthesized from a polyacrylonitrile (PAN) precursor or a graphite fiber synthesized from a pitch precursor.
