Recently, rapid development of intelligent wearable electronic equipment has triggered great needs for flexible and lightweight portable energy storage systems. Here, we demonstrate a low-cost ($ 0.5 m-2) and low density carbonized facial tissue paper (FCP) for high-conductive NiCo2S4 nanotubes assisted novel ultra-flexible solid-state supercapacitors (SSCs). The hydrothermal synthesized FCP-900@NiCo2S4 electrodes in this paper only have a density of 5 mg cm−2 and show large specific capacitance of 3115 mF cm−2 at 2 mA cm−2. Based on the high performance of FCP-900@NiCo2S4 electrodes, the as assembled SSCs can deliver an energy density of 1.2 mWh cm−3, high power density of 58.16 mW cm−3. It also shows great bending-state capacitive performance with high capacitance retention after 5000 cycles, providing a new opportunity for developing high-performance flexible wearable energy storage devices.
