Electrolyte flame retardant additive and preparation method and application thereof

The invention discloses an electrolyte flame retardant additive, a preparation method of the flame retardant additive and application of the flame retardant additive in a battery electrolyte. The electrolyte flame retardant prepared in the invention is a five-membered cyclic phosphite compound, can be used as an additive in a secondary electrolyte to improve the thermal stability of the electrolyte, while a cyclic structure can form an SEI film on the surface of a negative electrode material, so that the additive can obviously improve the high and low temperature, circulation, storage and other properties of a secondary battery, and the prepared secondary battery not only can be effectively improved in safety, but also can be improved in comprehensive properties. The preparation method ofthe flame retardant additive has the advantages of low raw material cost, simple preparation process steps, safe operation, high product purity and little environmental pollution.

NEW TYPES OF AMINOMETHYL ORGANOPHOSPHORUS COMPOUNDS

We studied aminomethylation of various PH acids their derivatives containing highly reactive PH, PSi, POSi and PC(O) fragments: tris(trimethylsilyl)phosphine, trimethylsilyl esters of phosphorus(III) acids, pivaloylphosphonite, and hydrospirophosphoranes.Chloro-, alkoxy- or dialkylaminomethylamines, dialkylformamide acetals, azomethines, and enamines were used as aminomethylating reagents.Convenient methods for synthesizing previously unknown or difficult-to-obtain organic compounds of two-, three-, four, and five-coordinate phosphorus containing a P-C-N fragment were proposed.
