This study utilizes metal–organic framework (MOF)-derived NiCo2O4 with porous carbon (PC) as the cathode to fabricate both symmetric and asymmetric supercapacitor devices an optimized anode (NiCo2O4/PC, activated (AC), polyaniline (PANI)) aqueous electrolytes. Initially, NiCo2O4/PC material was synthesized from a bimetallic–organic (NiCo-BTC MOF) using carefully thermal conditions. Following comprehensive characterizations, employed in fabrication of solid-state by meticulously selecting electrode–electrolyte pair maximize performance. To achieve this, electrochemical characterizations NiCo2O4/PC/NF (NF: Ni foam) were carried out various The 1.0 M potassium hydroxide (KOH) electrolyte demonstrated most promising performance for composite. Subsequently, KOH-based gel evaluate three devices. These included two devices, NiCo2O4/PC/NF–AC/NF NiCo2O4/PC/NF–PANI/NF, well one device, NiCo2O4/PC/NF–NiCo2O4/PC/NF. Notably, NiCo2O4/PC/NF–PANI/NF device exhibited energy density almost 3.23 3.78 times higher than those NiCo2O4/PC/NF-NiCo2O4/PC/NF respectively. long-term stability system, analyzed over 2000 charge–discharge cycles time series analysis, reveals insights into its behavior extended duration. illustrated efficacy PANI (instead AC) MOF-derived material. Furthermore, aforementioned high-performing integrated power LED, demonstrating practical applicability.
