  • Organohalosilane and use thereof in electrolytes of non-aqueous lithium ion batteries
    Patent number: 9765096
    Abstract: A method for preparation of an organohalosilane represented by formula I is disclosed. The method comprises: contacting an alcohol with metal sodium to yield a sodium alcoholate; contacting the sodium alcoholate with a halogen silane compound for an etherification reaction; and adding dropwise a fluorinating agent for a fluorination reaction. The organohalosilane is used for preparation of an electrolyte solution of a non-aqueous lithium ion battery.
    Type: Grant
    Filed: May 24, 2016
    Date of Patent: September 19, 2017
    Assignee: GUANGZHOU INSTITUTE OF ENERGY CONVERSION, CHINESE ACADEMY OF SCIENCES
    Inventors: Lingzhi Zhang, Hao Luo, Yongjin Mai

  • Organohalosilane and use thereof in electrolytes of non-aqueous lithium ion batteries
    Patent number: 9359384
    Abstract: An organohalosilane represented by formula I, where R1, R2, and R3 independently, at each occurrence, represent —(CH2)xCH3 where x is an integer from 0 to 5, or a halogen substituent where the halogen is F or Cl, and at least one substituent from R1, R2, and R3 is the halogen substituent; R4 is a C1-C5 alkoxyl or a tertiary amine represented by —NR5R6, where R5 and R6 independently, at each occurrence, represent a same or different C1-C5 alkyl; m is an integer from 1 to 20; and n is an integer from 0 to 5. The organohalosilane is used for preparation of an electrolyte solution of a non-aqueous lithium ion battery.
