In recent years, a substantial advancement in flexible and wearable consumer electronics has expedited the research community to develop flexible, lightweight, and sophisticated energy storage systems via cost-effective and safe preparation methods. In this context, we propose a state-of-the-art hot-water therapy (HWT) method to trigger nickel-copper-cobalt layered double hydroxide nanosheets on flexible conductive fabric (Ni-Cu-Co LDH NSs/CF). In the proposed HWT method, de-ionized water plays a significant role in generating NSs from CF in a manner similar to germination of plants in a farmland. Exploiting the morphological and inherent traits of the active material, the Ni-Cu-Co LDH NSs/CF electrode delivered maximum areal capacity of 104.2 mu Ah cm(-2) with an outstanding cycling stability of 124.5%. Furthermore, a supercapattery that fabricated with Ni-Cu-Co LDH NSs/CF and activated carbon delivered high areal capacitance of 232 mF cm(-2) at 2 mA cm(-2). Additionally, the device exhibited maximum areal energy and power densities of 0.0734 mWh cm(-2) and 15 mW cm(-2), respectively. A prototype flexible charge-storage station has been also designed using the fabricated supercapatteries in conjunction with a flexible solar cell panel to demonstrate the real-time feasibility of our flexible device. The prolific and state-of-the-art HWT approach can initiate substantial advancements in the rational design of ecofriendly electrode materials for wearable applications.
