However, the theoretical energy density is limited by the concentration of Mn (CH 3 COO) 2 (2.78 M) in the electrolyte in the zinc-manganese flow battery. Among the various manganese salts, the solubility of MnCl 2 in the aqueous solution can exceed 6.42 M, which is much higher than that of MnSO 4 (4.17 M) or Mn (CH 3 COO) 2 (2.78 M) .
In a word, the addition of Gly changed the solvation structure of Mn 2+ and Cl - ions and helped Mn 2+ from the MnCl 2 electrolyte reversibly convert to MnO 2 without Mn 3+ and Cl 2, thereby ensuring the stable long-term cycling of a zinc-manganese flow battery with MnCl 2 electrolyte.
