Abstract:

In this paper, we have reported a facile in situ synthesis approach to incorporate Nickel oxide (NiO) into Polyaniline (PANI) matrix and evaluate its morphological properties by scanning electron microscopy and electrochemical performance as supercapacitor electrode material by using Galvanostatic charge-discharge (GCD). PANI having excellent electrical conductivity, simple acid doping/base de-doping chemistry and relatively high pseudo capacitance proves to be a promising electrode material. Doping of NiO nanoparticles is very effective in enhancing the capacitive performance of PANI by additional pseudocapacitive contribution. PANI/NiO nanocomposite stores charge both through pseudocapacitive and electric double layer mechanism which leading to higher coulombic efficiency, enhanced energy and power density.
