Abstract

Mn-based materials are considered as promising cathode candidates for aqueous Zn-ion batteries (AZIBs). Herein, Mg²⁺ incorporation is developed to stabilize MnO, which can promote the reaction kinetics and improve the electrochemical performance. In addition, Mg-doped MnO exhibits 80.7 mA h g⁻¹ reversible capacity after 2000 cycles even at a high rate of 2 A g⁻¹.
