Electrochemical Stability of ZnMn2O4: Understanding Zn-Ion Rechargeable Battery Capacity and Degradation
Abstract
We present a refined Mn–Zn–H2O Pourbaix diagram with the emphasis on parameters relevant for the Zn/MnO2 rechargeable cells. It maps out boundaries of electrochemical stability for MnO2, ZnMn2O4, ZnMn3O7, and MnOOH. The diagram helps to rationalize experimental observation on processes and phases occurring during charge/discharge, including the position of charge/discharge redox peaks and capacity fade observed in rechargeable aqueous Zn-ion …
