摘要

本文设计了一种具有聚焦形态的新型组合,在合成了 CrVO4 (CV) 纳米粒子和聚吡咯纳米管(PNT 或 P)之后,制备了 PNT 和 CrVO4 的互锁复合材料 1PCV1、1PCV2、2PCV1 和 2PCV2,以研究超级电容器的应用。为了证实样品的合成,对其进行了结构和光谱表征。对插层复合材料 2PCV1 进行了三探针和双探针设置测试,结果表明其储能效果最佳。在循环伏安法(CV)周期和伽马静电荷放电(GCD)曲线上,2PCV1 的比电容(Cs)卓越值分别为:10 mV s-1 速率下 1745.60 F g-1 和 0.625 A g-1 电流密度下 1545.62 F g-1;在 5 mV s-1 扫描速率下,界面控制和传输控制的 Cs 占界面部分的 55.13%,传输部分的 44.87%。电化学阻抗谱(EIS)研究提供了 0.86 n 因子,溶液电阻 Rs 为 1.48 Ω,电荷转移电阻为 0.166 Ω。在 0.83 A g-1 电流密度下,通过双探针设置获得的比功率和比能量值也分别高达 416.68 W kg-1 和 45.14 Wh kg-1。此外,通过连续运行 5000 次伏安循环,研究了铯值的保留率,超级电容器装置中的保留率为 96.23%。

Synthesis of Poly-Pyrrole Nanotubes/Chromium Vanadate Composite as Wired Interlocks to Achieve an Asymmetric Supercapacitor Device with Scaled Electrochemical Energy Parameters

Herein, a novel combination with a focused morphology is designed after synthesizing CrVO4 (CV) nanoparticles and poly-pyrrole nanotubes (PNT or P) to prepare the interlocks of the composites of PNT and CrVO4 as 1PCV1, 1PCV2, 2PCV1, and 2PCV2 to study the supercapacitor application. Structural and spectral characterizations are perpetuated to confirm the synthesis of the samples. Results furnishing best energy storage are obtained for the intercalated composite 2PCV1 examined for three-probe and two-probe set-up. The excel values for specific capacitance (Cs) for 2PCV1 concerning the Cyclic voltammetry (CV) cycle and Galvanostatic Charge Discharge (GCD) curve are 1745.60 F g−1 at 10 mV s−1 rate and 1545.62 F g−1 at 0.625 A g−1 current density studied along with interface controlled and transport-controlled Cs with a contribution of 55.13% interface part and 44.87% transport part at 5 mV s−1 scan rate. Electrochemical Impedance Spectroscopy (EIS) study has provided 0.86 n-factor with solution resistance Rs of 1.48 Ω, and a charge transfer resistance of 0.166 Ω. The respective specific power and specific energy values obtained through the two-probe set-up are also interestingly high 416.68 W kg−1 and 45.14 Wh kg−1 at 0.83 A g−1 current density. Also, the retention % in Cs values is studied by running 5000 continuous voltammetric cycles with 96.23% retention in supercapacitor device.
