▎ 摘  要

NOVELTY - A flexible textile-based silver electrode comprises a flexible textile substrate having a surface, and a polymeric silver electrode wire attached to the surface of the flexible textile substrate. The electrode wire comprises an elastomeric material, and silver flakes homogeneously distributed throughout the elastomeric material. The fraction of silver (Ag0) in the silver flakes is 89-95% relative to silver (Ag+). The hysteresis ( Delta R/R0) of the flexible textile-based silver electrode following 100 cycles of being elongated by 50% of its original dimension is 1.1-2, preferably 1.86. USE - Flexible textile-based silver electrode used for sweat-activated battery for device (all claimed). ADVANTAGE - The electrode has highly increased conductivity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) sweat-activated battery, which comprises a textile substrate, a cathode comprising a cathode sweat-activated active material and an elastomeric material (M1) on the textile substrate, an anode comprising a sweat-activated active material and an elastomeric material (M2) on the textile substrate, and a current collector formed from a polymeric silver electrode wire attached to the surface of the flexible textile substrate. The electrode wire comprises an elastomeric material (M3), and silver flakes homogeneously distributed throughout the third elastomeric material. A current is produced by the battery when the battery is placed into an environment comprising an aqueous composition comprising an inorganic chloride salt and an organic acid; (2) device, which comprises one or more sweat-activated batteries and a capacitor; and (3) manufacture of flexible textile-based silver electrode, which involves (a) providing a composite material comprising a flexible textile substrate having a surface and a polymeric silver electrode wire attached to the surface of the flexible textile substrate, and (b) contacting the composite material with an aqueous solution comprising a non-toxic chloride salt and an organic acid for a period of time to form the flexible textile-based silver electrode.
