With the surging demand for flexible and portable electronic devices featuring high energy and power density, the development of next-generation lightweight, flexible energy storage devices is crucial. However, achieving the expected energy and power density of supercapacitors remains a great challenge. This work reports a facile plasma-enabled method for preparing supercapacitor electrodes made of MoS nanosheets grown on flexible and lightweight N-doped carbon cloth (NCC). The MoS/NCC presents an outstanding specific capacitance of 3834.28 mF/cm at 1 mA/cm and energy density of 260.94 µWh/cm at a power density of 354.48 µW/cm. An aqueous symmetric supercapacitor fitted with two MoS/NCC electrodes achieved the maximum energy density of 138.12 µWh/cm and the highest power density of 7,417.33 µW/cm, along with the excellent cycling stability of 83.3 % retention over 10,000 cycles. The high-performance energy storage ASSSs (all-solid-state supercapacitors) are demonstrated to power devices in both rigid and flexible operation modes. This work provides a new perspective for fabricating high-performance all-solid-state flexible supercapacitors for clean energy storage.
随着对具有高能量和功率密度的柔性便携式电子设备的需求激增，开发下一代轻质、柔性储能设备至关重要。然而，实现超级电容器预期的能量和功率密度仍然是一个巨大的挑战。这项工作报道了一种简便的等离子体辅助方法，用于制备由生长在柔性轻质氮掺杂碳布（NCC）上的MoS纳米片制成的超级电容器电极。MoS/NCC在1 mA/cm²时呈现出3834.28 mF/cm²的出色比电容，在354.48 μW/cm²的功率密度下能量密度为260.94 μWh/cm²。配备两个MoS/NCC电极的水系对称超级电容器实现了138.12 μWh/cm²的最大能量密度和7417.33 μW/cm²的最高功率密度，以及在10000次循环中83.3%的出色循环稳定性。高性能储能全固态超级电容器（ASSs）被证明能够在刚性和柔性操作模式下为设备供电。这项工作为制造用于清洁能源存储的高性能全固态柔性超级电容器提供了新的视角。
