Abstract: An electrolyte composition and a metal-ion battery employing the same are provided. The electrolyte composition includes a metal halide, an organic compound, and a halogen-containing salt, wherein the halogen-containing salt has a structure represented by Formula (I) [Ca+]i[X−]j  Formula (I) , wherein M can be IA element, IIA element, IIIA element, IVA element, VA element, VIA element, transition metal, pyrrolium, pyrrolinium, pyrrolidinium, pyridinium, ammonium, imidazolium, indazolium, pyrimidinium, etc.; wherein A can be F, Cl, Br, or I; a=j/i; i is 1, 2, 3, or 4; j is 1, 2, 3, 4, 5, or 6. The molar ratio of the metal halide to the organic compound is higher than 2, and the molar ratio of metal halide to the halogen-containing salt is higher than 2. The metal halide is different from the halogen-containing salt.
