The invention relates to the technical field of synthesis of organosilicon compounds, in particular to a synthetic method of a lithium battery aid 3-cyanopropyldimethylfluorosilane. The synthetic method comprises dropwise adding 4-chlorobutytonitrile into a sodium water-free solvent, allowing to react to obtain a suspension of N=CCH2CH2CH2Na, and carrying out any one of two process routes to obtain 3-cyanopropyldimethylfluorosilane, wherein the route 1 includes subjecting N=CCH2CH2CH2Na to reaction with dimethyldichlorosilane to obtain 3-cyanopropyldimethylchlorosilane, and fluorinating to obtain 3-cyanopropyldimethylfluorosilane, and the route 2 includes fluorinating dimethyldichlorosilane to obtain dimethyldifluorosilane, and subjecting the dimethyldifluorosilane to reaction with N=CCH2CH2CH2Na to obtain the 3-cyanopropyldimethylfluorosilane. The synthetic method has the advantages that the raw materials are easy to attain, the cost is low, the purity is higher, reacting is easy, andthe synthetic method is economical and feasible.
