Abstract
A manganese–lead battery based on MnO<sub>2</sub>/Mn<sup>2+</sup> cathodic reaction and PbSO<sub>4</sub>/Pb anodic reaction was demonstrated. With an optimized deposition behavior and high solubility of MnO<sub>2</sub>, high areal capacity (50 mA h cm<sup>−2</sup>) and energy density (187 W h L<sup>−1</sup>) can be obtained.
