Abstract:

New and/or improved coatings, layers or treatments for porous substrates, including battery separators or separator membranes, and/or coated or treated porous substrates, including coated battery separators, and/or batteries or cells including such coatings or coated separators, and/or related methods including methods of manufacture and/or of use thereof are disclosed. Also, new or improved coatings for porous substrates, including battery separators, which comprise at least a matrix material or a polymeric binder, and heat-resistant particles with additional additives, materials or components, and/or to new or improved coated or treated porous substrates, including battery separators, where the coating comprises at least a matrix material or a polymeric binder, and heat-resistant particles with additional additives, materials or components are disclosed. Further, new or improved coatings for porous substrates, including battery separators, and new and/or improved coated porous substrates, including battery separators, new or improved coatings for porous substrates, including battery separators, which comprise at least (i) a matrix material or a polymeric binder, (ii) heat-resistant particles, and (iii) at least one component selected from the group consisting of a cross-linker, a low-temperature shutdown agent, an adhesion agent, and a thickener, and new and/or improved coated porous substrates, including battery separators, where the coating comprises at least (i) a matrix material or a polymeric binder, (ii) heat-resistant particles, and (iii) at least one component selected from the group consisting of a cross-linker, a low-temperature shutdown agent, an adhesion agent, a thickener, a friction-reducing agent, and a high-temperature shutdown agent are disclosed.
