Synthesis and physico-chemical property evaluation of PANI-NiFe2O4 nanocomposite as electrodes for supercapacitors

► PANI-NiFe2O4 composite prepared by in situ-chemical oxidative polymerization method. ► NP1 exhibits high SC (448 F/g) and energy density (50.4 Wh/kg) at 1 mA/cm2. ► 80% of capacitance retained even after 1000 cycles at current density of 10 mA/cm2.
