Researchers developed a high-solubility pyrene tetraone derivative (PTO-PTS) that enhances AOFB energy density and stability. This monomer enables reversible four-electron storage, achieving 90 Ah/L and maintaining 100% capacity retention after 5,200 cycles. Aqueous organic flow batteries (AOFBs) are a promising technology for integrating renewable energy and enhancing electricity grid storage, thanks to their inherent safety [...]from SciTechDaily https://ift.tt/exDfJXK
