Abstract

Read online

Quasi-solid-state Zn-air batteries are limited by sluggish kinetics and low temperature incompatibility. Here, the authors use a single-atom catalyst and an organohydrogel electrolyte to enable a 100 mA cm−2 cycling current density at 25 °C and a −60 to 60 °C operational window.
