Anion-Assisted Regulation of Solvation Structure for High-Performance Manganese-Organic Batteries

Rechargeable manganese metal batteries (MMBs) have recently gained attention owing to the high abundance, large theoretical capacity, and low redox potential (-1.19 V vs SHE) of Mn compared with Zn. However, Mn anodes suffer from severe hydrogen evolution in aqueous electrolytes, while in nonaqueous systems, corrosion suppression is accompanied by sluggish Mn²⁺ desolvation and high polarization. Moreover, the limited availability of cathodes capable of reversible Mn²⁺ stora
