Herein, we are reporting a simple, economic, easy to handle, scalable and reproducible mechanochemical i.e. rotational chemical bath deposition (R-CBD) approach for synthesis of well adhered nano-flakes ZnFe2O4 thin films (NFs-ZnFe2O4) with uniform morphology on stainless steel (SS) substrate, in comparison with nano-grain ZnFe2O4 thin films (NGs-ZnFe2O4) prepared using conventional CBD approach. The influence of rotation on the evolution of nano-flakes morphology in NFs-ZnFe2O4 is also investigated. The porous NFs-ZnFe2O4 thin films demonstrated excellent pseudocapacitor properties with higher specific capacitance 768 Fg -1 at high current density 5 mA cm -2 , stability upto 5000 cycles (88% retention), higher energy density (106 Wh kg -1 ) and power density (18 kW kg -1 ) compared to NGs-ZnFe2O4. The results were also found to be higher than those reported earlier for MFe2O4 based systems.
