NOVELTY - The electrolyte comprises zinc compound that is made of zinc fluoro-borate, zinc carbonate, zinc chloride, zinc chlorate, zinc cyanide, zinc fluoride, zinc silicon-fluoride, zinc sulfur oxide, zinc nitrate or selenium-oxide. Solubility of the zinc compound is in 0.1-8M in electrolyte. Non-aqueous organic solvent comprises carbonate, ester group, ether group, ketone group, organo sulfur group, organic phosphorus group, aprotic solvent, tripropylphosphate, trisopropyl phosphate, tributyl phosphate, trihexylphosphate, triphenyl phosphate, tritolyl phosphate or polyethylene glycol dimethyl ether.    USE - Electrolyte for a zinc-air cell of a battery module of a secondary battery that is utilized as a power supply of an electrical machinery/apparatus (all claimed). Uses include but are not limited to a nickel-cadmium battery, a nickel metal hydride battery, a lithium-ion battery, an alkali-manganese dry cell battery and a zinc-air battery.    ADVANTAGE - The electrolyte continuously performs discharging and charging of a zinc air cell according to an operation state of an electrical machinery/apparatus.    DETAILED DESCRIPTION - The electrolyte is water system electrolyte or non-aqueous electrolyte, where the non-aqueous electrolyte comprises ethylene carbonate, propylene carbonate, butylene carbonate, dimethyl carbonate, diethyl carbonate, dipropyl carbonate, dibutyl carbonate, ethyl methyl carbonate, methylpropyl carbonate, ethylpropyl carbonate, fluoroethylene carbonate, dibuthyl ether, tetraglyme, diglyme, dimethoxyethane, tetrahydfuran, 2-methyltetrahydrofuran, 1,3-dioxolans, 1,4-dioxane, 1,2-dimethoxyethane, 1,2- diethoxyethane, 1,2- DBE, acetonitrile, dimethylformamide, methyl formate, ethyl formate, propyl formate, butyl formate, methyl acetate, ethyl acetate, propyl acetate, butylacetate, methyl propionate, ethyl propionate, propyl propionate, butylpropionate, methylbutyrate, ethyl butyrate, propylbutyrate, butyl butyrate, 2-butyrolactone, 2-methyl-2-butyrolactone, 3-methyl-2-butyrolactone, 4-methyl-2-butyrolactone, trimethyl phosphate, triethylphosphate or tris phosphate.
