Abstract

In this study, the plain MoO₃ and Ag-doped MoO₃ nanorods are anchored on a flexible fibrous carbon cloth using a hydrothermal method, and their performances are thoroughly evaluated by fabricating the supercapacitors using both types of nanorods. The doped substrate shows drastic enhancement in specific capacitance which is nearly four times greater than undoped MoO₃ nanorods at a current density of 0.5 mA/cm². Additionally, the Ag doped MoO₃ shows an excellent energy density of 43 µWh/cm². The superior performance of the doped nanorods is attributed to its pseudocapacitive behaviour, higher conductivity, and improved charge kinetics at the electrode–electrolyte interface, enabling a more efficient and potential supercapacitor-based energy storage system to drive future low power flexible and wearable electronic devices.

基于柔性碳布上掺银 MoO3 纳米棒的高能量密度超级电容器

本研究采用水热法在柔性纤维碳布上锚定了普通 MoO3 纳米棒和掺杂 Ag 的 MoO3 纳米棒，并通过使用这两种纳米棒制造超级电容器全面评估了它们的性能。在电流密度为 0.5 mA/cm2 时，掺杂基底的比电容比未掺杂的 MoO3 纳米棒高出近四倍。此外，掺银 MoO3 还显示出 43 µWh/cm2 的出色能量密度。掺杂纳米棒的卓越性能归功于它的伪电容行为、更高的电导率以及电极-电解质界面电荷动力学的改善，从而使基于超级电容器的储能系统更高效、更有潜力，以驱动未来的低功耗柔性可穿戴电子设备。
