Abstract

Metal-incorporated oxy-carbide nanostructures are pondered as a potential material for future-generation energy storage, conversion, and harvesting devices. Here, we proposed the synthesis of porous boron-oxy-carbide (PBOC) nanosheets via a hydrothermal-assisted annealing process and revitalized their utilization in wearable electrochemical supercapacitor devices. Physiochemical analysis, such as X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Brunauer–Emmett–Teller (BET), and high-resolution transmission electron microscopy (HR-TEM) analysis, revealed the formation of PBOC nanosheets and further coating on carbon cloth (CC) electrodes for wearable supercapacitor (WESC) fabrication. The fabricated WESC using PBOC nanosheets exhibited better capacitive behavior with superior device capacitance of (121.82 F g⁻¹ and 304.56 mF cm⁻²), excellent energy density (43.31 Wh kg⁻¹ and 0.16 mWh cm⁻²) with better cyclic life over 10,000 prolonged cycles. Further, the PBOC-CC WESC revealed an extraordinary rate capacity with excellent self-discharge behavior and high-power density of (16,000 W kg⁻¹ and 1.6 mW cm⁻²) compared to state-of-the-art WESCs. In addition, we displayed a self-powered energy system by integrating solar cells with the PBOC-CC WESC to prove its ability in wearable devices. These cumulative results suggest the priority of PBOC nanosheets as a potential electrode material that may be suitable for application in upcoming electrochemical wearable technology.

多孔硼氧碳化物杂化纳米片：高性能可穿戴超级电容器的新型电极材料

金属含氧碳化物纳米结构被认为是未来一代能量存储、转换和收集装置的潜在材料。在这里，我们提出了通过水热辅助退火工艺合成多孔碳化硼氧纳米片（PBOC），并振兴其在可穿戴电化学超级电容器器件中的应用。物理化学分析，如x射线衍射（XRD）， x射线光电子能谱（XPS），布鲁瑙尔-埃米特-泰勒（BET）和高分辨率透射电子显微镜（HR-TEM）分析，揭示了PBOC纳米片的形成和进一步涂层在碳布（CC）电极上用于制造可穿戴超级电容器（WESC）。使用PBOC纳米片制备的WESC具有良好的电容性能，器件电容为121.82 F g−1和304.56 mF cm−2)，能量密度为43.31 Wh kg−1和0.16 mWh cm−2，循环寿命超过10,000次。此外，与最先进的WESC相比，PBOC-CC WESC显示出非凡的倍率容量，具有优异的自放电行为和高功率密度（16,000 W kg - 1和1.6 mW cm - 2）。此外，我们还展示了一个将太阳能电池与PBOC-CC WESC集成的自供电能源系统，以证明其在可穿戴设备中的能力。这些累积的结果表明，PBOC纳米片作为一种潜在的电极材料，可能适合应用于即将到来的电化学可穿戴技术。图形抽象

期刊介绍： Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field. The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest. Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials. Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
