| titleOfInvention | Electrolyte solution composition for lithium secondary battery and lithium secondary battery comprising the same |
| abstract | The present invention relates to an electrolyte composition for a lithium metal secondary battery and a lithium metal secondary battery comprising the same, and the secondary battery according to the present invention is a carbonate-based electrolyte that can be used at a high operating voltage of 4 to 4.3V, particularly ethylmethyl carbonate ( As the magnesium nitrate additive is dissolved in a mixed solvent of EMC) and fluoroethylene carbonate (FEC), the lithium ion solvation structure is changed by the magnesium nitrate during charging and discharging, and the lithium ion accepts the electrons of the nitrate anion to form a negative electrode As reduced in the phase, spherical lithium is uniformly deposited on the negative electrode, thereby suppressing dendrite growth of the lithium electrode and facilitating Li electrodeposition/desorption reactions, thereby improving current efficiency (CE). In addition, Mg ions in the electrolyte are bonded to the surface of lithium metal to form a protective film (SEI layer) in the form of a Li-Mg alloy, and nitrate ions also combine with lithium to form a protective film (SEI layer), so that these inorganic components are SEI By strengthening the strength of the layer to suppress dendrite growth on the surface of lithium metal and stabilizing the lithium metal, the cycle performance of the lithium secondary battery can be improved. |
