Abstract

Disclosed herein are soluble absorbing glass mats or AGM separators for VRLA, AGM or VRLA AGM batteries. Such glass mats can be prepared by mixing insoluble glass fibers with soluble materials. Upon exposure to a suitable solvent, the solubles dissolve or decompose creating voids within the glass mat. The voids enhance the absorption of solvents within the glass mat. The solubles may be acid soluble glass fibers or microfibers.
