尖晶石铁酸钴锚定聚吡咯复合材料作为储能应用阴极材料的电化学研究

In this work, cobalt ferrite@polypyrrole (CoFe₂O₄@PPy) nanocomposites have been synthesized by a simple in-situ chemical oxidative polymerization process and this facile polymer nanocomposite (PNC) electrodes have been utilized for electrochemical energy storage applications. The physical and electrochemical properties of the nanocomposite has been characterized. The electrochemical properties of the prepared PNC electrode have been investigated in 6 M KOH aqueous electrolyte. This PNC has been fabricated as an electrode and examined in a two-electrode system, which has obtained a specific capacitance of 69.63 F g⁻ 1 at current density of 2 A g −1 . The fabricated device has an excellent cyclic stability of 68.86% after GCD 20000 cycles and a superior energy density of 24.75 Wh kg −1 and an excellent power density of 4255.28 W kg −1 at a current density of 25 A g −1 .
