The integration of energy storage systems into intermittent renewable energy sources in power grids ensures the continuity of the energy supply in a balanced and efficient way. Novel rechargeable zinc ion and zinc hybrid aqueous technologies constitute paradigmatic examples of promising alternative energy storage systems for large‐scale applications, due to their intrinsic low cost, environmental friendliness, safety, high power density, and ease of operation. This work evaluates the performance improvement of zinc/LiFePO₄ and zinc/LiMn₂O₄ batteries through the incorporation of an alternative chloride‐based electrolyte formulation inspired in Leclanché battery technology and also, in recently reported secondary zinc–air batteries. The use of this alternative electrolyte shows an increased working voltage and improves capacity retention for both zinc/LiFePO₄ and zinc/LiMn₂O₄ batteries. This work analyses for the first time the specific energy of zinc‐based hybrid aqueous batteries in a functional cell, by means of the incorporation of light zinc anode and Li⁺‐based cathode which comprises superior active material loading. This approach demonstrates the feasibility of reversible zinc‐based hybrid aqueous batteries with more than 90 W h kg⁻¹_{Active materials} as to 13 W h kg⁻¹_{Active materials} of the baseline technology.
