Description
The development of high-performance flexible aqueous zinc batteries requires innovative manufacturing protocols, suitable electrode composition and large area, three-dimensional architecture that results in exceptional electrochemical properties even under mechanical deformation. This work presents a unique approach for synthesizing flexible alkaline Ni-Zn batteries utilizing Ni?S?/NiO composite cathode over highly flexible and durable micro/nano-textured stainless steel mesh with excellent electrochemical performance. The binder-free composite cathode was developed through nickel electrodeposition followed by hydrothermal processing to create Ni?S?/NiO composite nanowires. The innovative anode design employs zinc composite coated on a pressed copper foam, significantly outperforming conventional zinc foil configuration. The Ni3S2/NiO/SSE composite cathode delivers an impressive specific capacity of 452 mAh/g, demonstrating excellent electrochemical properties at the electrode level. This advanced electrode architecture also enables the assembled device to showcase outstanding performance, delivering 316 mAh/g specific capacity at 1 A/g, a remarkable energy density of 553 Wh/kg, and exceptional power density of 11.19 kW/kg, substantially exceeding most reported aqueous zinc battery systems. Further, the device maintains stable electrochemical performance across various bending conditions, demonstrating superior mechanical flexibility essential for the advanced electronics and flexible energy storage applications. 2025 Elsevier B.V.
