Improving zinc–air batteries is challenging due to kinetics and limited electrochemical reversibility, partly attributed to sluggish four-electron redox chemistry. Now, substantial strides are noted with two-electron redox chemistry and catalysts, resulting in unprecedentedly stable zinc–air batteries with 61% energy efficiencies.
