Conventional　aqueous　zinc-ion　batteries　(AZIBs)　encounter　challenges　that　compromise　the　reversibility　and　stability　of　the　zinc　anode.　To　mitigate　these　issues,　this　study　proposes　the　incorporation　of　highly　polar　1,2-propylene　glycol　(PG)　as　a　co-solvent.　PG＇s　capacity　to　form　hydrogen　bonds　with　water　molecules　effectively　reduces　water　activity　and　facilitates　uniform　Zn2+　deposition　by　establishing　a　negatively　charged　adsorption　layer　via　PG　molecules.　By　optimizing　the　water-to-PG　ratio,　a　tailored　electrolyte　system　was　developed,　and　the　electrochemical　behavior　of　Zn2+　during　the　solvation-to-deposition　process　was　systematically　elucidated　through　experimental　and　theoretical　analyses.　The　findings　indicate　that　AZIBs　incorporating　20　%　PG　achieve　a　cycle　life　of　2500　h　at　a　current　density　of　1　mA　cm-　2　and　a　capacity　of　1　mA　h　cm-　2,　underscoring　the　pivotal　role　of　PG　in　stabilizing　the　zinc　anode　interface.　The　assembled　Zn||VO2　full　cells　demonstrated　exceptional　performance　in　the　20　%　PG　electrolyte,　sustaining　1100　stable　cycles　even　at　a　high　rate　of　20C.　Moreover,　AZIBs　with　20　%　PG　exhibited　superior　ionic　conductivity　at　low　temperatures,　enabling　Zn||Zn　symmetric　cells　to　operate　stably　for　2500　h　at-20　degrees　C.　These　results　highlight　the　significant　potential　of　20　%　PG　in　practical　energy　storage　systems.
