Abstract

In this study, we report a novel copper chromite-polyaniline (CuCr₂O₄-PANI) nanocomposite electrode material for fabrication of high-performance energy storage. First CuCr₂O₄ is synthesized via sol-gel driven epoxide method followed by its nanocomposite with PANI through in situ chemical oxidative polymerization method. The micro structure and morphology of CuCr₂O₄-PANI are characterized by various techniques. The as synthesized nanocomposite with optimized ratio exhibits a specific capacity of 479.2C g⁻¹ at 2 mV s⁻¹ and high cycling stability with 93.9% capacity retention after 1000 charge-discharge cycles. Furthermore, it shows energy and power densities of 26.6 Wh kg⁻¹ and 3600 W kg⁻¹, respectively. The change in electrochemical properties of the nanocomposite with increasing CuCr₂O₄ loading is explained in detail.
