Abstract
Systems and methods which provide flexible zinc ion (Zn-ion) battery configurations with shape memory are described. For example, embodiments of flexible shape memory yarn batteries (SMYBs) may be fabricated using shape memory material wire, filament, and/or fiber and flexible conductive material yarn as flexible substrate materials. In accordance with some embodiments, Nickel-Titanium-based alloy wire may be coated with a zinc material to provide a flexible anode electrode for a SMYB. Additionally or alternatively, flexible stainless steel (SS) yarn may be coated with a manganese dioxide (MnO) material to provide a flexible cathode electrode for a SMYB of embodiments. An aqueous electrolyte may be combined with the flexible cathode and anode electrodes to provide a SMYB in accordance with the concepts herein. The aqueous electrolyte may, for example, comprise a polymer gel electrolyte (e.g., gelatin-borax polymer gel electrolyte).
