The invention belongs to the technical field of electrolyte of lithium ion batteries and particularly relates to electrolyte with a thermocuring effect. The electrolyte is prepared from lithium salt, a carbonic ester organic solvent, a film forming additive, a polymer monomer and an initiator, wherein the polymer monomer is one or more of N,N-4,4-diphenylmethylenebismaleimide, a bismaleimide oligomer, 1,3-dioxolane and neopentyl glycol diacrylate. By comparison with the prior art, the polymer monomer can be subjected to a thermo-crosslinking reaction under the action of the initiator at the temperature of 90-130 DEG C to cure the electrolyte and stop an electrode reaction, so that overheating protection is provided for batteries, and the safety performance of the batteries is improved. Additionally, the invention further provides a preparation method of the electrolyte with the thermocuring effect. The preparation method is simple to operate, and the electrolyte prepared with the preparation method is good in quality.
