The invention relates to a synthetic method of 3-hydroxy-propionaldehyde. The synthetic method mainly solves the problem that the yield of the 3-hydroxy-propionaldehyde is low in the prior art. The synthetic method of the 3-hydroxy-propionaldehyde comprises the following steps: a) performing a complexing reaction in a solvent on N-heterocyclic carbene ligand and cobalt salt so as to obtain a catalyst solution; and b) adding oxacyclopropane and synthesis gas, and reacting to obtain the 3-hydroxy-propionaldehyde, wherein the N-heterocyclic carbene ligand is of a following structure, R1 is selected from alkyl, nitryl or halogen atom of C1 to C9; R2 to R3 are selected from one of alkyl or alkenyl, aryl or substituted aryl, and nitrogen heterocyclic radical, and one to six carbon atoms are contained in R2 to R3 independently; and X is selected from one of chlorine ion, bromide ion and iodide ion. Through the technical scheme, the technical problem is preferably solved, and the synthetic method can be used in the industrial production of the 3-hydroxy-propionaldehyde.

The invention provides a monomer for a lithium ion battery gel electrolyte and a preparation method thereof, a lithium ion battery gel electrolyte and a preparation method thereof, and a preparation method of a lithium ion battery. The general formula of the monomer is: R is an alkyl group of a dibasic alcohol, an alkyl group of a dibasic epoxy or an alkyl group of a diglycidyl ether; A1, A2, A3, and A4 are carbon atoms An alkyl group with a number of 1-10; Z1, Z2, Z3, and Z4 are organic esters with a carbon number of 1-10 and an alkenyl group. The preparation method of the monomer comprises the steps of: dissolving phosphorus oxychloride in an organic solvent; adding at least one of dibasic alcohol, dibasic epoxy or diglycidyl ether; adding alkenyl esters and acid-binding agent triethylamine; optionally add the corresponding catalyst triphenylphosphine when the binary epoxy is selected; react under the reflux state of the organic solvent to obtain the monomer for lithium ion battery gel electrolyte. As a result, the safety risk of ignition and explosion of the lithium-ion battery in a strongly oxidized state can be reduced.
