Construction of porous nanosheet arrays of transition‐metal sulfides (TMSs) holds great potential for energy storage. Herein, a one‐step hydrothermal process is employed for the construction of porous Ni_1.43Fe_.5Co_.5S_.97 nanosheet arrays (NFCS‐NS) on the nickel foam as a proper positive electrode for hybrid supercapacitor. Owing to the appealing structural features, the NFCS‐NS depicts a high capacity of 1156 C g⁻¹ at 2 A g⁻¹, desirable rate capability of 81.1 %, and significant cyclability of 92.9 %. Also, a promising hybrid device (NFCS‐NS//AC) based on NFCS‐NS and activated carbon (AC) represents a reasonable energy density of 57.3 Wh kg⁻¹ at 807.04 W kg⁻¹ and a notable power density of 20000 W kg⁻¹ at 40 Wh kg⁻¹. Therefore, our current research can introduce an effective strategy for the fabrication of high‐performance electrodes with porous architectures.
