Abstract Microscale, wire‐shaped flexible supercapacitors are gaining significant attention due to the growing demand for wearable electronics and microrobotic technologies. Among various materials, copper sulfide stands out as an ideal candidate because of its superior electrochemical properties, which can be attributed nanostructured composition. This structure enhances surface area, reduces ion transport distances, improves charge–discharge kinetics. However, conventional electrode synthesis methods—such annealing hydrothermal processes—are limited by long production times scalability issues, making them unsuitable supercapacitor development. In this study, innovative fabrication technique using atmospheric pressure plasma jet (APPJ) both treatment material is proposed. By integrating APPJ with a winding mechanism, roll‐to‐roll processing continuous enabled, significantly enhancing manufacturing process. The fabricated microscale electrodes demonstrate high specific capacitance (153.39 mF cm −2 ), energy density (15.48 µWh excellent retention (91.32%) after 30 000 cycles. Furthermore, solid‐state asymmetric assembled in coaxial configuration. exhibits exceptional flexibility storage performance, underscoring practical applicability proposed method advanced electronics.
