Regulating the Coordination Environment of H2O in Hydrogel Electrolyte for a High-Environment-Adaptable and High-Stability Flexible Zn Devices

Highlights A hydrogel electrolyte regulation strategy of the water coordination environment can effectively restrain the hydrogen evolution reaction, Zn corrosion and dendrite formation in the wide-temperature ranges. Prepared high-environment-adaptable hydrogel electrolytes (HEA-3) exhibits a high...

Description
Summary:Highlights A hydrogel electrolyte regulation strategy of the water coordination environment can effectively restrain the hydrogen evolution reaction, Zn corrosion and dendrite formation in the wide-temperature ranges. Prepared high-environment-adaptable hydrogel electrolytes (HEA-3) exhibits a high reversibility of zinc deposition/stripping (coulombic efficiency of 99.4% for Zn||Cu cell). Zn-based device using HEA-3 electrolyte can do cycling over 30,000 cycles at a large current density of 2 A g−1 at − 40 °C and also can do normal cycling even at -70 °C.
