Abstract: The invention relates to the technical field of a lithium ion battery, particularly to a lithium ion battery electrolytic solution capable of discharging at a low temperature. The lithium ion battery electrolytic solution is prepared from the following raw materials in parts by weight: 33.1 parts of electrolyte, 52 parts of organic solvent, 17-19 parts of organic additive and 0.23-0.34 parts of inorganic additive, wherein the inorganic additive is K<2>SO<3> or K<2>ClO<4>. By adoption of the electrolytic solution taking K<2>SO<3> or K<2>ClO<4> as the inorganic additive, a stable and dense solid electrolyte interface (SEI) film can be formed on an electrode, and high cycling performance is represented.
