超级电容器的性能往往受到其内部电阻的影响，因为它会导致不利的影响，如能量耗散和充电/放电过程中的电荷传输延迟。在本研究中，我们制备了单片金属纳米线阵列电极，旨在抑制超级电容器的内阻，并检查了存在于纳米线阵列电极中的缺陷结构的影响。通过恒电流充放电测试、循环伏安法和电化学阻抗谱研究了超级电容器的性能。
Performance of supercapacitors is often influenced by their internal resistance since it causes unfavorable effects such as energy dissipation and delay of charge transport during charging/discharging. In the present study, we prepared monolithic metal nanowire array electrodes in aiming at suppressing the internal resistance of supercapacitors, and examined the influence of the defect structures present in the nanowire array electrodes. Performance of the supercapacitors was investigated by using galvanostatic charge/discharge measurement, cyclic voltammetry, and electrochemical impedance spectroscopy.
