''Density/solidity'' of recombinant battery separator material—its influence on both separator and battery performance in valve-regulated lead ...
The ability of RBSM to provide a very high porosity is a major reason why this material functions well in valve-regulated lead–acid (VRLA) batteries. Investigations have shown that the separator, besides providing space for the acid, must also provide a force on the plate active-material to eliminate the effects of premature capacity loss.
In most batteries, the separators are either made of nonwoven fabrics or microporous polymeric films. Batteries that operate near ambient temperatures usually use organic materials such as cellulosic papers, polymers, and other fabrics, as well as inorganic materials such as asbestos, glass wool, and SiO 2 .
