This work describes the development of a woven carbon fiber and thermoset polyester resin based structural supercapacitor via three-dimensional (3D) printing. The specific surface area and capacitance of the electrodes were increased by hydrothermally synthesized N-doped Zn-Co selenide nanowires on the surface. The supercapacitor with N@ZnCoSe2-MXene exhibited an energy of 2.69 Wh kg–1, a power density of 43.20 W kg–1, and a Coulombic efficiency of 88.8% at 1000 mA g–1 of current density. The cyclic stability and multifunctionality of the device were satisfactory, and the capacitance retention was 83.7% at the same current density after 6000 consecutive charge–discharge cycles. The device’s high tensile strength (637.679 MPa) and modulus (36.92 GPa), with an impact energy absorption capacity of 2.22 J g–1, indicated its mechanical robustness. The device exhibits a comparable performance under various weather conditions. It retains 39.11 F g–1 of specific capacitance, 4.62 Wh kg–1 of energy, and 67.29 W kg–1 of power density at 70 °C, while it retains 7.87 F g–1 of specific capacitance, 1.78 Wh kg–1 of energy, and 20.98 W kg–1 of power density at −5 °C.

这项工作描述了通过三维 (3D) 打印开发基于编织碳纤维和热固性聚酯树脂的结构超级电容器。通过在表面上水热合成 N 掺杂 Zn-Co 硒化物纳米线，增加了电极的比表面积和电容。具有 N@ZnCoSe 2 -MXene的超级电容器显示出 2.69 Wh kg –1的能量、43.20 W kg –1的功率密度以及 1000 mA g –1时的 88.8% 的库仑效率。电流密度。该器件的循环稳定性和多功能性令人满意，在相同电流密度下连续6000次充放电循环后的电容保持率为83.7%。该装置的高拉伸强度 (637.679 MPa) 和模量 (36.92 GPa) 以及 2.22 J g –1的冲击能量吸收能力表明其机械坚固性。该设备在各种天气条件下表现出相当的性能。它在 70 °C 时保持 39.11 F g –1的比电容、4.62 Wh kg –1的能量和 67.29 W kg –1的功率密度，同时保持 7.87 F g –1的比电容、1.78 Wh kg –1能量和 20.98 W kg –1-5 °C 时的功率密度。
