in 2020 utilising Cu-CAT-NWAs and PPy membrane by an easy hydrothermal procedure. For solid-state flexible SCs, this material might be employed without restriction as linked and selfstanding electrodes. Cyclic voltammetry was used to assess the built electrodes' long-term survivability in terms of flexibility, temperature, capacitance, and stability under flat, different bending angles, and twisted situations. Electrodes have a high capacity for energy storage, a long lifespan, and a 91% efficiency rate of up to 8000 cycles. To enhance the capacitive performance of various organic/inorganic hybrid conductive MOFs, this material's increased electrochemical characteristics may be employed . According to Na Wu et al., Cu2O/Cu@C nano sheets electrochemical electrodes have specific capacitance, current density, efficiency, and cyclic stability of 665 F g -1 , 0.5 Ag -1 , 83%, and 5000 cycles, respectively . Cu-Co-P hollow spheres and CuFeS2 nano sheets were combined to create an assembly that was tested as an SCs electrode with remarkable electrochemical characteristics. The positive electrode was found to have a specific capacitance of 2043.3 F g -1 and the negative electrode to have a capacitance of 654.3 F g -1 . Despite having low-efficiency values, both electrodes were sturdy and kept working after 8000 cycles at 97% and 95%, respectively . Crystalline Cu3(HHTP)2 NWAs electrochemical material was produced using the chemical vapour deposition process, and the test outcomes were very positive. For instance, the greatest capacitance reported was 41.1 F cm 2 , and it persisted at a 55% level with current densities increasing from 0.25 to 5 A g -1 . The electrode maintained 80% of its initial capacitance after a lengthy 5000-cycle procedure .
