The resulted material after a discharge of Zn-MnO2 cell is a mixture of various oxide and hydroxide. The recycling of spent batteries cathodic materials from them is of great scientific and economic interest. In this work, the MnO2 was recycled by chemical methods, the MnO2 was oxidized using hydrogen peroxide (H2O2) at neutral pH, the obtained materials were characterized by different methods including cyclic voltammetry, impedance spectroscopy, atomic absorption spectroscopy and X-ray diffraction. The preliminary results demonstrated that by chemical oxidation with hydrogen peroxide (H2O2 ) is a suitable method for recuperation of a pure MnO2 and it could be used in a plant for recycling batteries.
