Fractal structure of a LiMn2O4 film electrode has been investigated and its fractal dimensions was determined using different electrochemical techniques, viz. cyclic voltammetry and chronoamperometry. The results obtained from both these methods are in good agreement indicating the reliability of the estimated D f. The fractal study of the LiMn2O4 film electrode suggests a complex surface with high fractal dimension. In addition, length scales of the electrode surface were also calculated.
