In current work, a polyester suede is initially coated with Ni through a facile electroless deposition method as the conductive scaffold, followed by the growth of conductive and pseudocapacitive NiCo2S4 nanosheets. Besides, to achieve the aim of standardized batch processing of the flexible SCs, sewing and polydimethylsiloxane (PDMS) sealing techniques are employed, and SC devices are successfully assembled and encapsulated. It's worth noting that the resulting SCs demonstrate stable electrochemical performance with a high specific capacitance of 83.59 F/g at a current density of 2 A/g and a high energy density of 22 Wh/Kg at a power density of 750 W/Kg under the working voltage window of 1.5 V, as well as effective waterproof properties.
