Abstract

KxMnO2 exhibits a layered structure that provides attractive properties as a cathode material for secondary Li batteries. Therefore, in the present study, our attention was paid to the hydrothermal preparation of highly homogenous KxMnO2 in presence of citric acid. Out X-ray diffraction and SEM studies indicated that the final product markedly change the phase and morphology on vary the concentration of citric acid. The prepared products have also studied with the help of TGA and DTA. EDS and DCP made the chemical analysis of the compounds. The impedance data of the materials were explained in terms of the compounds formed.
