Abstract
anions to induce the Hofmeister effect can greatly improve the tensile strain and flexibility of the hydrogels. The PA addition dramatically enhances the ionic conductivity and increases the affinity between the electrolyte and zinc plate. Consequently, the PVA/PA hydrogels exhibit remarkable electrochemical performances with stable full-cell cycling in zinc ion storage and capability in inhibiting Zn dendrite growth.
