摘要： A solidified, conformable porous composite having interconnected pores and containing thermally-expanded polymer microspheres and a particulate filler material is disclosed herein. An energy storage device containing a solidified, conformable porous composite having interconnected pores and comprising thermally-expanded polymer microspheres and particulate filler material is disclosed herein. A method of making a solidified, conformable porous composite in which no solvent is introduced into and extracted from the composite in the formation of pores is disclosed herein.

摘要： This disclosure relates to battery separators for use in lead acid batteries. In particular, the disclosure relates to nonporous polymer sheets in which the porosity manifests itself after cavitation and/or biaxial stretching to form a microporous membrane. The disclosure also relates to nonporous polymer sheets in which the porosity manifests itself after dissolution of an acid soluble filler to form a microporous membrane. In addition to meeting all battery performance requirements, these microporous membranes eliminate environmental and health concerns because they do not require the use of an organic solvent during their production.
