Abstract: ABSTRACT REGULATING REDOX-ACTIVE CENTRES IN NON-CONJUGATED COVALENT ORGANIC NETWORK AS A HIGH-PERFORMANCE ASYMMETRIC SUPERCAPACITOR The present invention relates to regulating redox-active centres in non-conjugated covalent organic networks for high- performance asymmetric supercapacitors. The invention addresses inefficient charge stabilization in non-conjugated systems arising from electrostatic repulsion between localized redox sites. Non-conjugated covalent organic networks comprising strategically distributed redox-active units, including triazine and anthraquinone moieties, are designed to enhance pseudocapacitive charge storage. Controlled tuning of the type, density, and spatial distribution of redox centres enables efficient electron transfer, improved ion diffusion, and electrochemical stability. In a preferred embodiment, the covalent organic network is employed as an anode material in an asymmetric supercapacitor device assembled with an activated carbon cathode, a separator, and an aqueous electrolyte. The device exhibits high capacitance, fast charging capability, slow discharging behaviour, and long-term cycling stability. The invention provides a scalable and versatile material design strategy that bridges the performance gap between conjugated and non-conjugated organic electrode materials, supporting practical energy storage applications.
