  • Additives for high voltage lithium ion batteries
    Patent number: 11757131
    Abstract: This invention relates to an electrolyte composition for a lithium ion battery comprising a lithium salt in a non-aqueous solvent containing an additive comprising a compound of formula R3SiOP(O)nF2; wherein each R independently is a hydrocarbyl group; and n is 0 or 1; and wherein the additive is substantially free from (R3SiO)3P(O)n and (R3SiO)2P(O)nF. Electrochemical cells and batteries also are described.

  • Additives for high voltage lithium ion batteries
    Patent number: 10840552
    Abstract: This invention relates to a method for preparing an electrochemical cell comprising the sequential steps of preparing a solution of a lithium salt in an non-aqueous solvent containing an additive compound, and maintaining the solution at a temperature in the range of about 20 to about 30° C. for about 5 to 10 days to form an aged electrolyte; assembling an electrochemical cell from an anode, a cathode, and the aged electrolyte; and electrochemically subjecting the electrochemical cell to formation cycling. The additive compound comprises one or more compounds selected from the group consisting of: (R3SiO)3B, (R3SiO)3XY, (R3SiO)3P, (R?O)3PO, (R3Si)3X?, R3SiOS(O)2R?; (R3Si)OC(?O)R?; wherein each R and R? independently is a hydrocarbyl group; X is P or B; Y is O or S; X is Ti or Al. Electrochemical cells and batteries also are described.
