Sulfur-containing additive based on ethylene sulfate, electrolyte containing sulfur-containing additive and lithium ion battery

The invention provides a sulfur-containing additive based on ethylene sulfate, an electrolyte containing the sulfur-containing additive and a lithium ion battery, belongs to the technical field of lithium ion batteries, and aims to improve the stability of an SEI film and improve the Li conductivity of the SEI film so as to improve the high and low temperature performance of the lithium ionbattery. The structural formula of the additive is based on ethylene sulfate, and an organic molecular chain segment containing a lithium salt functional group is grafted on a cyclic molecular structure of the additive.

Sulfate preparation method

The invention relates to the field of organic synthesis, and especially relates to a sulfate preparation method. The invention provides a sulfate preparation method. According to the preparation method, a compound represented by a formula (II) reacts with sulfuryl fluoride in the presence of a reaction solvent to prepare a compound represented by a formula (I). During the sulfate preparation process, the introduction of water and chlorine ions is avoided effectively, the situation that the product is degraded and the chlorine ion content is high is avoided therefore; moreover, the steps of thepreparation method are simple and short, the raw material are common chemical products on the market, the kinds of raw materials and the side reactions are few, and the yield is high. The manufacturing cost is low, only recyclable organic solvents are used, the reaction byproduct is a single inorganic salt solid and can be easily recovered, no wastewater is generated, the environment is better protected, and the sulfate preparation method is green and environmentally friendly and is suitable for industrial large scale production.

Cyclic sulphate preparation method

The invention relates to the field of organic synthesis and especially relates to a cyclic sulphate preparation method. The sulphate preparation method disclosed by the invention comprises the step ofreacting a compound shown in formula II with sulfuryl chloride under the reaction solvent existence condition to prepare and obtain a compound shown in formula I. The sulphate preparation method disclosed by the invention has the characteristics of brief steps, small side reaction, simpleness in aftertreatment, small three wastes, low manufacturing cost, suitability for industrial large-scale production and the like.
