Abstract
A metal alloy for use in a wire included in an electrochemical cell is disclosed having an amorphous structure, microcrystalline grains, or grains that are sized less than about one micron. In various embodiments, the microcrystalline grains are not generally longitudinally oriented, are variably oriented, or are randomly oriented. In some embodiments, the microcrystalline grains lack uniform grain size or are variably sized. In some embodiments, the microcrystalline grains have an average grain size of less than or equal to 5 microns. In some embodiments, the metal alloy lacks long-range crystalline order among the microcrystalline grains. In some embodiments, the wire is used in a substrate used in the electrochemical cell. In some embodiments, the metal alloy is formed using a co-extrusion process comprising warming up the metallic alloy and applying pressure and simultaneously passing a core material through a die to obtain a composite structure.
