Novel Composites: Synergistic Effects of Graphene Oxide, Conducting Polymers and Metal Oxides in Supercapacitor Electrodes

The development of high-efficiency electrode materials for supercapacitors (SCs) has garnered significant attention, with conducting polymers (CPs) emerging as promising candidates due to their high porosity, cost-effectiveness, ease of synthesis, and tunable electrical conductivity. However, CPs often face limitations in terms of cycle stability and energy density. Recent research has focused on the synergistic integration of CPs with metal oxides (MOs) and carbon-based materials, forming composite electrodes that exhibit enhanced conductivity, mechanical durability, and improved electrochemical performance. This review highlights the novel approach of combining CPs with MOs and graphene derivatives to address these limitations, leading to superior energy storage capabilities. By presenting an overview of recent advancements in this field, we aim to elucidate the mechanisms underlying these synergistic interactions and their impact on electrode performance. This article underscores the potential for innovation in the design of next-generation supercapacitors, paving the way for more efficient and durable energy storage solutions.
