Cation-regulated MnO2 reduction reaction enabling long-term stable zinc–manganese flow batteries with high energy density

Aqueous Zn–Mn flow batteries (Zn–Mn FBs) are a potential candidate for large-scale energy storage due to their high voltage, low cost, and environmental friendliness. However, the unsatisfactory performance due to the sluggish MnO2 reduction reaction (MnRR) kinetics leads to low discharge voltage (t...
