| titleOfInvention | Ternary positive electrode material electrolyte of high-voltage lithium ion battery and preparation method thereof |
| abstract | The invention discloses a ternary cathode material electrolyte of a high-voltage lithium ion battery and a preparation method thereof, wherein the ternary cathode material electrolyte of the high-voltage lithium ion battery comprises 15-20% of a lithium salt mixture, 71.2-79.7% of a high-pressure-resistant organic solvent, 3-5% of a flame retardant and 2.3-3.8% of an auxiliary additive; the lithium salt mixture comprises lithium hexafluorophosphate and lithium phosphates; the high-pressure-resistant organic solvent is cyclic carbonate, chain carbonate and a nitrile compound, the flame retardant is dimethyl methylphosphonate, and the auxiliary additive is tris (pentafluorophenyl) phosphine and lithium fluorozirconate; according to the invention, by adding the auxiliary additives of tris (pentafluorophenyl) phosphine, lithium fluorozirconate and the flame retardant of dimethyl methylphosphonate, the electrolyte containing the function is relatively stable in performance, the high-pressure cycle performance of the prepared lithium ion battery under 3-5V is improved, and the thermal stability between the anode and the electrolyte is improved. |
