Structural and electrochemical properties of recycled active electrodes from spent lead acid battery and modified with different manganese dioxide contents

The sample doped with small MnO2 content (x = 5mol%) used as working electrode in the measurements of cyclic voltammetry shows a good reversibility of the voltammogram, also improved the electrochemical properties, namely an increased stability in acidic electrolyte environments and offers an alternative for obtaining of electrodes for rechargeable batteries.
