Title:
ELECTROLYTE AND LITHIUM SECONDARY BATTERY COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2019/221456
Kind Code:
A1
Abstract:
The present invention relates to an electrolyte for a lithium secondary battery and a lithium secondary battery comprising same. More specifically, the present invention relates to an electrolyte for a lithium secondary battery which maintains a uniform concentration of lithium ions on the surface of a lithium metal anode even if the electrolyte contains only a small amount of an additive comprising a functional group forming a bond with a lithium metal and a polyethylene oxide chain interacting with lithium ions, such that growth of lithium dendrites can be suppressed.
