“…18 Conducting polymer polypyrrole (PPy) composites with rGO have been extensively studied for supercapacitor applications due to their synergistic effect which resulted in longer cycle life, higher specic capacitance and higher energy density compared to pure PPy. 19 Based on the literature, in this research work, we aim to convert the post-consumer EPS waste into a self-standing electrode by incorporating rGO into it for supercapacitor applications. This is an extremely simple, yet a new approach to employ the non-conducting waste polymer material which is harmful to the environment for energy storage applications.…”

“…The graphene/PPy electrode composites could be prepared by various methods, mainly including physical blending, in situ chemical polymerization of pyrrole in the presence of graphene, and electrodeposition of PPy onto graphene substrates. 19 While the former two methods could produce composites in large quantities, the subsequent electrode fabrication for supercapacitors often necessitates the addition of binders and conductive agents to some extent compromising the porosity and electroactive sites. We recently reported a one-step approach for fabrication of a graphene/PPy composite film directly on current collector to yield the freestanding electrode.…”

Improving the morphological structure of active materials is a reliable strategy for the fabrication of highperformance supercapacitor electrodes. In this study, we introduce a feasible approach to constructing the graphene/polypyrrole (PPy) composite film implanted onto the current collector through a two-step electrochemical deposition method utilizing MnO 2 as an intermediary template. The reduced graphene oxide (rGO) hydrogel film is first hydrothermally grown on a carbon cloth (CC) substrate to obtain a porous rGO@CC electrode on which MnO 2 is electrodeposited. Then the as-prepared rGO/MnO 2 @CC electrode is subjected to the electrochemical polymerization of pyrrole, with MnO 2 acting as an oxidizing template to facilitate the oxidative polymerization of pyrrole, ultimately yielding an rGO/ PPy composite film on CC. The PPy synthesized via this methodology exhibits a distinctive interconnected structure, resulting in superior electrochemical performance compared with the electrode with PPy directly electrodeposited on rGO@CC. The optimized electrode achieves an impressive specific capacitance of 583.6 F g −1 at 1 A g −1 and retains 83% of its capacitance at 20 A g −1 , with a capacitance loss of only 9.5% after 5000 charge−discharge cycles. The corresponding all-solid-state supercapacitor could provide a high energy density of 22.5 Wh kg −1 and a power density of 4.6 kW kg −1 , with a capacitance retention of 82.7% after 5000 charge− discharge cycles. Furthermore, the device also demonstrates good flexibility performance upon bending at 90 and 180°. This work presents an innovative method for the preparation of carbon material/conducting polymer electrodes with specific structural characteristics and superior performance.

In this study, graphene/polypyrrole (RGO/PPy) electrodes with porous structures were prepared by electrochemical codeposition and reduction. The porous structure not only enhances the effective contact area of the electrodes but also actively promotes the diffusion efficiency of the electrolyte ions. As a result, a maximum capacitance of 1091.2 mF•cm −2 at 1 mA•cm −2 is achieved for the 0.2-RGO/PPy electrode prepared using the deposition solution containing 0.2 mg•mL −1 of GO. The 0.2-RGO/ PPy maintains a capacitance of 78.4% at 10 mA•cm −2 . In particular, the 0.2-RGO/PPy-based supercapacitor exhibits a stack capacitance of up to 28.3 F•cm −3 . Furthermore, the supercapacitor exhibits excellent mechanical flexibility with a 93.3% capacitance retention, even under 180°bending. This study demonstrates the significant potential of RGO/PPy electrodes for high-performance energy storage systems.
