Aqueous zinc-ion batteries are promising due to inherent safety, low cost, toxicity, and high volumetric capacity. However, issues of dendrites side reactions between zinc metal anode the electrolyte need be solved for extended storage cycle life. Here, we proposed that an additive with intermediate chelation strength ion-strong enough exclude water molecules from metal-electrolyte interface not too strong cause a significant energy barrier ion dissociation-can benefit electrochemical stability by suppressing hydrogen evolution reaction, overpotential growth, dendrite formation. Penta-sodium diethylene-triaminepentaacetic acid salt was selected such purpose. It has suitable chelating ability in aqueous solutions adjust solvation sheath can readily polarized under electrical loading conditions further improve passivation.

Zn metal as one of promising anode materials for aqueous batteries but suffers from disreputable dendrite growth, grievous hydrogen evolution and corrosion. Here, a polycation additive, polydiallyl dimethylammonium chloride (PDD), is introduced to achieve long-term highly reversible plating/stripping. Specifically, the PDD can simultaneously regulate electric fields electrolyte Zn/electrolyte interface improve Zn2+ migration behaviors guide dominant (002) deposition, which veritably detected by Zeta potential, Kelvin probe force microscopy scanning electrochemical microscopy. Moreover, also creates positive charge-rich protective outer layer N-rich hybrid inner layer, accelerates desolvation during plating process blocks direct contact between water molecules anode.

Aqueous electrolytes are highly important for batteries due to their sustainability, greenness, and low cost. However, the free water molecules react violently with alkali metals, rendering high-capacity of alkali-metal anodes unusable. Here, confined in a carcerand-like network build quasi-solid aqueous (QAEs) reduced molecules' freedom matched low-cost chloride salts. The formed QAEs possess substantially different properties than liquid molecules, including stable operation without gas evolution. Specifically, can directly cycle water-based environment suppressed growth dendrites, electrode dissolution, polysulfide shuttle. Li-metal symmetric cells achieved long-term cycling over 7000 h (and 5000/4000 Na/K cells), all Cu-based exhibited Coulombic efficiency 99%. Full metal batteries, such as Li||S attained high efficiency, long life (over 4000 cycles), unprecedented energy density among rechargeable batteries.
