The successive ionic layer adsorption and reaction (SILAR) experimental process has used to develop a high-efficiency electrode of MFe2O4 (M= Ni, Co & Mn) on substrates at ambient temperature. Structural, morphological and electrochemical properties have investigated using X-ray diffraction (XRD), scanning electron microscope (SEM) and electrochemical test station, respectively. Hydrangea Macrophylla flower-like morphology has observed and tuned with varying Fe concentration. Formation of MFe2O4 demonstrates the efficient electrochemical behavior and the specific capacitance has evaluated ~1380, ~972 and ~815 Fg 1 for CoFe2O4 (CF), NiFe2O4 (NF) and MnFe2O4 (MF) respectively at a current density of 1 Ag 1. Also, the develop electrodes maintain excellent cyclic retention ~92%, ~89% and ~86% for CF, NF, and MF respectively up to 5000 cycles. Further, asymmetric solid-state supercapacitor (ASC) devices have fabricated using the best compositions of MFe2O4 as positive electrode and carbon black (CB) as a negative electrode, and successfully illuminate a 1.8 V commercial LED.
