In accordance with at least selected embodiments, the present application or invention is directed to novel or improved porous membranes or substrates, separator membranes, separators, composites, electrochemical devices, batteries, methods of making such membranes or substrates, separators, and/or batteries, and/or methods of using such membranes or substrates, separators and/or batteries. In accordance with at least certain embodiments, the present application is directed to novel or improved porous membranes having a coating layer, battery separator membranes having a coating layer, separators, energy storage devices, batteries, including lead acid batteries including such separators, methods of making such membranes, separators, and/or batteries, and/or methods of using such membranes, separators and/or batteries. The disclosed separators and/or batteries have improved charge acceptance, improved surface conductivity, improved oxidation resistance, reduced acid stratification, improved resistance to metal contamination induced oxidation, reduced black residue, improved wettability, and/or improved stiffness. 1. A lead acid battery separator comprising a porous membrane or substrate having at least one electrically non-conductive , conductive or semiconductive layer , film , coating , deposition , or material comprising at least one of particles , fibers or materials of at least one of silica , fumed silica , silicon oxide , alumina , aluminum oxide , metal , metal oxide , cellulose , cellulosic material , glass , fiber glass , carbon , conductive carbon , or combinations , blends or mixtures thereof on at least one side thereof.2. The lead acid battery separator according to claim 1 , comprising a conductive carbon selected from graphite claim 1 , graphene claim 1 , carbon nanotubes claim 1 , graphene oxides claim 1 , carbon fibers claim 1 , and combinations claim 1 , blends or mixtures thereof.3. The lead acid battery separator according to claim 1 , comprising ...
