ABSTRACT:
The alkaline storage battery comprises a positive electrode, a negative electrode, a separator, and alkaline electrolyte. The separator is a single layer of synthetic fiber non-woven fabric. Treating the separator to increase either the amount of fiber interconnection at the surface or the amount the fibers are broken apart at the surface or both improves separator strength without sacrificing permeability. This prevents internal short circuits, reduces internal pressure, and significantly improves battery lifetime.
