Abstract
Porous carbon materials were prepared from polyurethane foam waste (PFW) via a rapid carbonization method. The potential applications of the derived porous carbon materials as the cathode active material in zinc-ion hybrid capacitors (ZHCs) were investigated. The porous carbon material prepared at 800 °C, PFW-800, possesses a specific surface area of 1223.6 m2g−1. When PFW-800 was applied as the cathode active material in ZHCs, the assembled ZHC showed a high specific capacitance of 434.1 F g−1 at 0.2 A g−1. Meanwhile, the energy density reached 212.1 Wh kg−1 at the power density of 190.3 W kg−1. Furthermore, the ZHC employing PFW-800 as the cathode active material demonstrated good rate capability and maintained over 90% capacitance retention after 5000 charge–discharge cycles. This work lays the foundation for the efficient utilization of polymer waste.
以聚氨酯泡沫废渣（PFW）为原料，采用快速碳化法制备多孔炭材料。研究了所得多孔碳材料作为锌离子杂化电容器正极活性材料的应用前景。在800℃下制备的多孔碳材料PFW-800具有1223.6 m2g−1的比表面积。当PFW-800作为正极活性材料应用于ZHC时，组装的ZHC在0.2 a g−1时具有434.1 F g−1的高比电容。同时，在功率密度为190.3 W kg−1时，能量密度达到212.1 Wh kg−1。此外，采用PFW-800作为正极活性材料的ZHC具有良好的倍率性能，在5000次充放电循环后保持90%以上的电容保持率。为聚合物废弃物的高效利用奠定了基础。图形抽象
