ELECTROLYTE FOR LITHIUM ION BATTERY AND LITHIUM ION BATTERY INCLUDING THE SAME

摘要

The present invention is a lithium sa Ether solvent; Fluorinated solvent; And a functional additive. Even if lithium metal is used as a negative electrode material, it prevents the growth of dendrite on the surface of the lithium metal during charging and discharging of the lithium ion battery, and uniform lithium electrodeposition (plating) ) Makes it possible. In addition, by suppressing side reactions with the lithium metal negative electrode and the electrolyte, it is possible to provide a lithium ion battery with remarkably improved stability and lifespan performance.
