| titleOfInvention | Lithium-ion secondary battery and its electrolyte |
| abstract | The invention provides a lithium ion secondary battery and its electrolytic solution. The electrolyte solution of the lithium ion secondary battery includes: a non-aqueous organic solvent; a lithium salt dissolved in the non-aqueous organic solvent; and an additive dissolved in the non-aqueous organic solvent. The additives are vinylene carbonate (VC), sulfonimide lithium-containing compound LiN(C x F 2x+1 SO 2 )(C y F 2y+1 SO 2 ) (wherein, x and y are positive Integer) and fluorinated 1,3-propane sultone having the structure of formula I; In formula I, R 1 , R 2 , and R 3 are each independently selected from fluorine atoms; the mass of the vinylene carbonate (VC) is 0.1% to 2% of the mass of the non-aqueous organic solvent; The concentration of the lithium-containing compound LiN(C x F 2x+1 SO 2 )(C y F 2y+1 SO 2 ) of imides is 0.02M-0.2M; the fluorinated 1,3 - The mass of propane sultone is 0.5% to 5% of the mass of the non-aqueous organic solvent. The lithium ion secondary battery includes the above electrolyte solution. The electrolyte solution of the lithium-ion secondary battery of the invention can improve the low-temperature discharge performance and high-temperature cycle performance of the lithium-ion secondary battery. |
