Breaking the Specific Capacity Limit: 409% Boost in Manganese-Based Redox Flow Batteries at High Current Densities with a MnO2 Semi-Solid Slurry Electrolyte

Abstract The common-ion effect of SO 4 2− limits the solubility of MnSO 4 to ≤ 1 M in conventional H 2 SO 4 electrolytes, resulting in low specific capacity of manganese (Mn)-based redox flow batteries (RFBs). Although MnO 2 semi-solid RFBs are expected to improve the specific ca...
