PASTING PAPERS AND CAPACITANCE LAYERS FOR BATTERIES COMPRISING MULTIPLE FIBER TYPES AND/OR PARTICLES
Articles and methods involving pasting papers and/or capacitance layers are generally provided. The pasting paper may comprise a capacitance layer, and/or a stand-alone capacitance layer may be provided. In some embodiments, a pasting paper may comprise a plurality of cellulose fibers, a plurality of multicomponent fibers, and a plurality of glass fibers. In some embodiments, a pasting paper may comprise a plurality of conductive species, a plurality of capacitive species, and/or a plurality of inorganic particles. In some embodiments, a pasting paper may be disposed on a battery paste, such as a battery paste for use in a lead-acid battery. In some cases, forming a battery plate may comprise disposing a pasting paper on a battery paste. In some cases, a lead-acid battery may be assembled by assembling a first battery plate comprising a pasting paper with a separator and a second battery plate.
