Macromolecular electrolyte engineering for tuning Zn-ion solvation chemistry and boosting H+ storage toward stable aqueous zinc-organic batteries

We demonstrate a macromolecular electrolyte engineering strategy to break the Zn 2+ solvation sheath using a porphyrin-based additive, which can facilitate the formation of the Zn-porphyrin complex and achieve superior electrochemical performance.
