Supercapacitors (SCs) have emerged as promising energy storage devices, offering flexibility and smart functionalities to meet the growing demands of modern applications. However, challenges such as limited conductivity and stability continue to hinder their performance. Herein, a conductive composite was designed by forming one-dimension rod-like conductive MOFs (Ni-HHTP) on the hierarchical nickel oxalate (Ni-OA). The extended conjugated system between Ni
