Flexible zinc–ion batteries maintain stable voltage after bending with new hydrogel electrolyte

Flexible zinc–ion batteries maintain stable voltage after bending with new hydrogel electrolyte

A research team led by Prof. Hu Linhua from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences has developed a highly durable hydrogel electrolyte for aqueous zinc–ion batteries (AZIBs) by using urea as a zincophilic solubilizer and zinc acetate (Zn(Ac)₂) salt—an affordable and environmentally friendly material.
