Compositions and papers made therefrom useful as separator materials in starved electrolyte lead/acid batteries described. The compositions comprise a mixture of 15 percent to 75 percent by weight of perlite, 20 percent to 70 percent by weight of glass fibers, and 5 percent to 20 percent by weight of acid-insoluble thermoplastic fibers, the latter preferably in the form of staple fibers. The glass fibers have diameters in the range of from 0.3 to 1.0 micrometers while the perlite has particle sizes in the range of from about 30 to about 100 micrometers. |
