Systems and methods which provide an aqueous gel polymer electrolyte having one or more additive therein selected to configure the aqueous gel polymer electrolyte, and batteries formed therewith, for improved performance are described. Aqueous gel polymer electrolytes may, for example, have an additive compound including boron (e.g., a borate ion-containing salt) therein to configure batteries formed using the aqueous gel polymer electrolyte to increase the ionic conductivity of the gel polymer electrolyte. The addition of borax in Zinc-ion battery gel electrolytes of embodiments is configured to enhance the dissociation of zinc ions and anions, and subsequently release more mobile zinc ions. Furthermore, the interaction between borax and divalent transition metal (Zn) in electrolyte according to embodiments may enhance the transportation of mobile zinc ions.
