NEGATIVE ELECTRODE FOR LITHIUM SECONDARY BATTERY AND LITHIUM SECONDARY BATTERY COMPRISING SAME

Document Type and Number:

WIPO Patent Application WO/2022/255630

Kind Code:

A1

Abstract:

The present invention relates to a negative electrode for a lithium secondary battery, comprising: a three-dimensional carbon structure coated with a fluorine-based polymer; and lithium metal introduced onto the outer surface and into the inside of the three-dimensional carbon structure coated with a fluorine-based polymer. By suppressing the generation of lithium dendrites, the lifespan characteristics of a lithium secondary battery comprising same can be improved.
