  • Patent number: 10985428
    Abstract: Improved battery separators are disclosed herein for use in flooded lead-acid batteries, and in particular enhanced flooded lead-acid batteries. The improved separators disclosed herein provide for enhanced electrolyte mixing and substantially reduced acid stratification. The improved flooded lead-acid batteries may be advantageously employed in applications in which the battery remains in a partial state of charge, for instance in start/stop vehicle systems. Also, improved lead-acid batteries, such as flooded lead-acid batteries, improved systems that include a lead-acid battery and a battery separator, improved battery separators, improved vehicles including such systems, and/or methods of manufacture and/or use may be provided.

  • Patent number: 10938010
    Abstract: Disclosed herein are soluble content absorbent glass mats or AGM separators for VRLA, AGM, or VRLA AGM batteries. Such glass mats may be prepared from insoluble glass fibers blended with soluble content materials. Upon exposure to a suitable solvent, the dissolving or solvating of the soluble content produces voids within the glass mat. The voids enhance the absorption of the solvent within the glass mat. The soluble content may be acid-soluble glass fibers or microfibers.

  • Publication number: 20210057699
    Abstract: A battery separator has performance enhancing additives or coatings, fillers with increased friability, increased ionic diffusion, decreased tortuosity, increased wettability, reduced oil content, reduced thickness, decreased electrical resistance, and/or increased porosity. The separator in a battery reduces the water loss, lowers acid stratification, lowers the voltage drop, and/or increases the CCA.
