The invention discloses a preparation method of propenyl-1, 3-sulfonic acid lactone, which needs simple devices, has simple technology and comprises the following steps: (1) bisulfite and sulphite aredissolved in water, prepared into aqueous solution, stirred in the temperature of 0-80 DEG C and dropwise added with propargyl alcohol for addition reaction; (2) synthetic fluid is added after beingacidized and reacted by strong acid; (3) the synthetic fluid is directly concentrated in low temperature, thus obtaining viscous mixture; (4) viscous mixture is added with a water-carrying agent and contains water under stirring; and (5) the water-carrying agent is separated and collected, and the collected water-carrying agent is concentrated and crystallized to obtain product propenyl-1, 3-sulfonic acid lactone. The propenyl-1, 3-sulfonic acid lactone prepared by the invention can be used as a lithium cell electrolyte additive.
