Abstract
A multi-layer separator for use in alkaline storage batteries is disclosed. In one aspect of the invention the separator comprises bibulous, non-membranous layers together with a coating of a relatively thin layer of a gelling agent applied to at least one side of one of the bibulous layers. In another aspect of the invention, outer bibulous, non-membranous layers sandwich and are bonded to a semi-permeable membranous layer with an adherent gelling agent to form a high-strength laminated separator. These separators find use in a variety of alkaline galvanic cells, particularly in rechargeable cells such as nickel-cadmium, nickel-zinc, silver-zinc, manganese dioxide-zinc, and similar cells.
