Enhancement of the Potential Window of Ppy Electrodes in the Presence of a Bis(Oxamato) Nickel(II) Complex for High‐Performance Supercapacitor
Abstract
<jats:title>Abstract</jats:title><jats:p>Enhancing the supercapacitors’ performance relies on the increased capacitance and voltage window, which are the current key challenges for developing new materials. In this study, the mononuclear Ni<jats:sup>II</jats:sup>‐bis(oxamato) complex ([<jats:sup><jats:italic>n</jats:italic></jats:sup>Bu<jats:sub>4</jats:sub>N]<jats:sub>2</jats:sub>[Ni(opba)], <jats:bold>1</jats:bold>) has been synthesized and used as a template in polypyrrole (PPy) based conductive polymer as a novel electrode material for supercapacitor applications. The surface and structural properties of PPy and PPy/<jats:bold>1</jats:bold> electrodes were studied using SEM and TEM to elucidate their interactions. The results of characterization techniques revealed that complex <jats:bold>1</jats:bold> altered the morphology, creating a prominent three‐dimensional globular structure in the PPy/<jats:bold>1</jats:bold> hybrid material without significant chemical modification. The electrochemical properties of PPy and PPy/<jats:bold>1</jats:bold> were investigated by CV, EIS, and GCD analyses. The PPy/<jats:bold>1</jats:bold> electrode demonstrated intense pseudocapacitive behavior, showing a significantly widened potential window and increased current compared to the PPy electrode, resulting in enhanced energy storage capacity within the material. This improvement was evaluated by testing a symmetric supercapacitor in a coin cell architecture with an alginate‐based gel acting as both electrolyte and separator. The maximum specific cell capacitance reached 41.6 F g<jats:sup>−1</jats:sup> at a current density of 0.2 A g<jats:sup>−1</jats:sup>, with a remarkable capacity retention of 97 % after 1000 galvanostatic charge/discharge cycles.</jats:p>
