The energy density of manganese-based flow batteries was expected to reach 176.88 Wh L -1. Manganese-based flow batteries are attracting considerable attention due to their low cost and high safe. However, the usage of MnCl 2 electrolytes with high solubility is limited by Mn 3+ disproportionation and chlorine evolution reaction.
High concentration MnCl 2 electrolyte is applied in manganese-based flow batteries first time. Amino acid additives promote the reversible Mn 2+ /MnO 2 reaction without Cl 2. In-depth research on the impact mechanism at the molecular level. The energy density of manganese-based flow batteries was expected to reach 176.88 Wh L -1.
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) .
However, its development has largely been stalled by the issues of high cost, safety and energy density. Here, we report an aqueous manganese–lead battery for large-scale energy storage, which involves the MnO 2 /Mn 2+ redox as the cathode reaction and PbSO 4 /Pb redox as the anode reaction.
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.
Iron-based flow batteries designed for large-scale energy storage have been around since the 1980s, and some are now commercially available. What makes this battery different is that it stores energy in a unique liquid chemical formula that combines charged iron with a neutral-pH phosphate-based liquid electrolyte, or energy carrier.
