Shock waves induced enhancement of electrochemical properties of CoFe2O4 nanoparticles for energy storage applications

Abstract In the present work, we have performed Raman spectral analysis, scanning electron microscopic analysis and electrochemical measurements of dynamic shock wave loaded cobalt ferrite nano-particles (CoFe2O4 NPs) for different number of shock pulses as that of 0, 50,100 and 150 such that the respective observations have been investigated and the results are reported. Interestingly, among the four samples, 50 shocks loaded sample has homogenous particle size distribution and a high value of specific capacitance due to the occurrence of the shock wave-induced dynamic re-crystallization. Based on the observed electrochemical properties, shock wave loaded CoFe2O4 NPs are strongly suggested for energy storage applications.
