The revived interest and research on the development of novel energy storage systems with exceptional inherent, environmentally benign and low cost for integration in large scale electricity grid and electric is now driven by the global energy policies. Within various technical challenges yet to be resolved despite extensive studies, the low cycle life of the zinc anode is still hindering the implementation of zinc batteries at industrial scale. This review presents an extensive overview of electrolytes for zinc batteries in relation to the anode issues which are closely affected by the electrolyte nature. studied aqueous electrolytes, from alkaline to acidic pH, as well as non-aqueous systems including and room temperature ionic liquids are reported. References from early rechargeable Zn-air research recent results on novel Zn hybrid systems have been analyzed. The ambition is to identify the challenges the electrolyte system and to compile the proposed improvements and solutions. Ultimately, all the based on zinc, including the more recently proposed novel zinc hybrid batteries combining the points of lithium-ion, redox-flow and metal-air systems, can benefit from this compilation in order to secondary zinc based batteries performance.
