Augmented gravimetric and volumetric capacitive performance of rare earth metal oxide (Eu2O3) incorporated polypyrrole for supercapacitor applications

Eu2O3 incorporated polypyrrole (PPy) based hybrid electrode material exhibits enhanced gravimetric and volumetric capacitance. Integration of Eu2O3 reforms morphological and electrochemical properties of PPy leading to attainment of enhanced porosity as well as packing density leading to augmented gravimetric and volumetric capacitance for the composite.202
