PASTING PAPER FOR BATTERIES COMPRISING MULTIPLE FIBER TYPES

Articles and methods involving pasting papers are generally provided. In certain 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， the average fiber diameter of each plurality of fibers is greater than or equal to 1 micron. In some embodiments， a pasting paper may have a thickness of less than 0.2 mm， an air permeability of less than or equal to 300 CFM， a 1.28 spg sulfuric acid wicking height of greater than 3 cm， and/or may be configured to have a dry tensile strength in a machine direction of greater than or equal to 1 lb/in after storage in 1.28 spg sulfuric acid at 75C for 168 hours. 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. Articles and methods involving pasting papers are generally provided.
