Abstract
Separators for storage batteries, particularly separators for sealed lead-acid storage batteries, comprise glass fibers entangled in the shape of a sheet without the use of a binder, a first portion being glass fibers having a fiber diameter smaller than 1 micron and a second portion being glass fibers having a fiber diameter larger than 5 microns, preferably larger than 10 microns, as well as an average fiber length of at least 5 mm. The inventive separators have high electrolyte retention, good mechanical strength, and good shape recovery.
