Ultrastable rechargeable manganese battery with solid-liquid-gas reactions

Abstract

A rechargeable manganese battery includes: (1) a first electrode including a porous, conductive support; (2) a second electrode including a catalyst support and a catalyst disposed over the catalyst support; and (3) an electrolyte disposed between the first electrode and the second electrode to support reversible precipitation and dissolution of manganese at the first electrode and reversible evolution and oxidation of hydrogen at the second electrode.
