Abstract:
Optimizing efficient electrode materials that combine high energy density, rapid charge transport, and excellent cycling stability remains a challenge for advanced supercapacitors. Here, we report the synthesis of an innovative copper(I)-based metal-organic framework (MOF), Cu3(NDI)3, prepared via a simple solvothermal method using N,N'-bis(3,5-dimethylpyrazol-4-yl)-naphthalene diimide (H2NDI-H) as a linker. Structural analyses (XRD, FTIR, SEM, EDX, and BET) confirmed the formation of a highly crystalline, porous MOF. Integration of this MOF into laser-induced graphene (LIG) matrices yielded hybrid electrodes with enhanced structural characteristics and electrochemical activity, compared to its only-LIG counterpart. Electrochemical studies (CV, CD, EIS) revealed that the LIG-MOF electrode exhibited the highest performance, delivering a specific capacitance of 4.6 mF cm-2 at 0.05 mA cm-2, and an areal energy density of 60.03 μWh cm-2 at a power density of 1292.17 μW cm-2, outperforming both LIG and MOF-LIG configurations. This enhancement arises from the synergetic interaction between the conductive LIG network and the redox-active Cu3(NDI)3 framework, highlighting the potential of LIG-MOF hybrids as next-generation materials for high-performance supercapacitors.
