| titleOfInvention | Lithium ion battery safety additive and lithium sulfonate imide electrolyte containing same |
| abstract | The invention relates to a lithium ion battery safety additive and a lithium sulfoimide electrolyte containing the same, wherein the lithium ion battery safety additive comprises tris (2, 4-di-tert-butylphenyl) phosphite and an auxiliary agent, the mass of the electrolyte is 1-4%, and the auxiliary agent is ethylene carbonate and/or propylene carbonate. The lithium salt is the combination of 1 or more than 2 of lithium sulfonate imine lithium salt and lithium dioxalate borate, lithium tetrafluoroborate and lithium hexafluorophosphate; the lithium sulfonate is lithium bis (fluorosulfonate) imide or lithium bis (trifluoromethanesulfonate) imide. The additive improves the flame retardance of the battery and inhibits the voltage rise of the battery during overcharge, the polymer generated by electropolymerization greatly increases the impedance of the battery under the condition of overcharge of the battery, and the rapid voltage rise of the battery is inhibited, so that the overcharge protection effect is realized. The electrolyte disclosed by the invention effectively reduces the flammability of the electrolyte and improves the thermal stability of the electrolyte. |
