Electrochemical Performance Studies of MnO2 Nanoflowers Recovered from Spent Battery

The electrochemical performance of MnO2 nanoflowers recovered from spent household zinc–carbon battery is studied by cyclic voltammetry, galvanostatic charge/discharge cycling and electrochemical impedance spectroscopy. MnO2 nanoflowers are recovered from spent zinc–carbon battery by combination of...
