Summary: The utilization of polyaniline as a linker to anchor nickel sulfide (NiS2) on the surface of graphene oxide (GO) with a hollow bowl-like structure leads to a unique material (NiS2@15PG) with enhanced electrical conductivity and ion diffusion properties. This modification significantly improves the charge transfer resistance and Warburg impedance of NiS2. The resulting NiS2@15PG exhibits high specific capacitance and excellent multiplicativity, making it a promising material for practical applications in supercapacitors.

Summary: In this study, a novel hybrid material consisting of cobalt hexacyanoferrate, multi-walled carbon nanotube with carboxyl functionalized, and polypyrrole was prepared as a supercapacitor element on a pencil graphite electrode. The hybrid material exhibited superior supercapacitive performance and long charge-discharge cycle life in an acidic medium. The specific capacitance of the hybrid composite reached 495.0 F g-1 under optimum coating conditions. Moreover, a symmetrical supercapacitor using the optimized electrodes successfully powered red, green, and blue LEDs.
