Abstract With the rapid development of wearable electronic devices, demand for flexible, durable, and high‐performance energy storage systems has increased significantly. Nevertheless, maintaining stable electrochemical performance during stretching while ensuring high stretchability mechanical stability remains a challenge. Herein, this study proposes novel type stretchable supercapacitors made from carbon nanotube (CNT) styrene‐butadiene‐styrene (SBS) composite scaffolds prepared on pre‐stretched fabrics using breath figure method. Hydrothermal treatment is then performed to grow NiCo‐LDH at treated fabrics. This method induces formation hierarchically porous structure under humidity conditions, controls hydrothermal growth in CNT/SBS scaffold, significantly enhances stability. The supercapacitor demonstrates remarkable retention 94% capacitance 80% tensile strain sustains small 8% degradation over 20 000 charge–discharge cycles, achieving specific 4948 mF cm⁻ 2 mA . device an density 801.6 µWh (400.6 Wh kg⁻¹) exhibits excellent power 3.5 mW (1749.5 W kg⁻¹). These properties make potential next‐generation smart wearables electronics.
