Lean-water hydrogel electrolyte for zinc ion batteries

open access: yesNature Communications, 2023
AbstractSolid polymer electrolytes (SPEs) and hydrogel electrolytes were developed as electrolytes for zinc ion batteries (ZIBs). Hydrogels can retain water molecules and provide high ionic conductivities; however, they contain many free water molecules, inevitably causing side reactions on the zinc anode.
