| titleOfInvention | A kind of vinyl sulfite derivative and its preparation method and application |
| abstract | The invention discloses a vinyl sulfite derivative and a preparation method and application thereof. The structural formula of the vinyl sulfite derivative of the present invention is: or wherein, R is a C 1 -C 8 perfluoroalkyl group. The preparation method of the vinyl sulfite derivative of the present invention comprises the following steps: firstly performing a halogenation reaction of vinyl sulfite to obtain 4,4-dihalogenated vinyl sulfite, and then performing a halogen replacement reaction with a fluorinating reagent, or First, the oxidation reaction of perfluoroalkylethylene is carried out to obtain perfluoroalkylethylene glycol, which is then subjected to a ring-forming reaction with trichloromethylsulfonyl chloride. The vinyl sulfite derivative of the invention has the advantages of simple preparation method, short production period, low production cost and high product purity, and adding the vinyl sulfite derivative to the electrolyte of lithium ion battery can widen the electrochemical window of the electrolyte system and improve the high voltage of the battery. The interface stability improves the high-voltage cycling performance of the battery. |
