Abstract With the urgent demand for wearable electronics and smart textiles in modern society, fabric‐based supercapacitors (FSCs) have attracted increasing attention due to their easy integration, high power density, long‐term stability. However, low energy density deformable capability of supply cause limitations actual applications. Here, a 1T‐MoS 2 @Ti 3 C T x heterostructure nonwoven fabric (NWF) with interfacial adhesion, electrical conductivity, mechanical deformability is developed, which great significance unitization as an advanced FSCs electrode. Owing designed aligned active interface, conductive network, situ coupling, NWF exhibits ion adsorption barrier, fast diffusion kinetics, accelerated electron transport, resulting large capacitance (425 F g −1 ) cycling stability (20 000 cycles) 1 m H SO 4 electrolyte. Additionally, corresponding solid‐state asymmetric (D‐SCs) provide 119.3 µWh cm −2 at 800.8 µW , realizing practical applications powering electroluminescent device, 2‐D code, sound‐controlled electronic fan. More importantly, D‐SCs exhibit robust power‐supply capability, maintaining 82.1%, 84.6%, 89.9% capacity retentions after 2000 cycles folding, twisting, bending conditions, respectively.
