Abstract

A wire mesh including a warp which includes a first nickel alloy wire having a first peak tensile strength; and a weft which includes a wire including nickel having a second peak tensile strength, wherein the first peak tensile strength is greater than or equal to the second peak tensile strength, is provided. A current collector and a zinc-air battery that includes the wire mesh are also provided.

Claims (43)
