Abstract
ZnMn₂O₄ (ZMO) cathode possesses a high theoretical capacity of 224 mAh g^-1 and high operating voltage (1.9 V vs. Zn²⁺/Zn) for aqueous Zn–ion batteries. However, the disproportionation reaction of Mn³⁺ leads to Mn dissolution in the ZMO cathode, deteriorating lifespan. In this study, we attempted to reduce Mn dissolution by..... More
