Abstract

A Mn-incorporated Ni(OH)₂/carbon fiber cloth (Mn-Ni(OH)₂/CFC) fabricated via a room-temperature solution route exhibited superior electrocatalytic activities of the oxygen reduction and urea oxidation reactions, delivering 12–21% energy saving in the charging process of Mn-Ni(OH)₂/CFC assembled Zn–air batteries in the presence of 0.5 M urea compared to the battery without urea.
