Title:
炭素系薄膜が形成された負極、この製造方法及びこれを含むリチウム二次電池
Document Type and Number:
Japanese Patent JP7065263
Kind Code:
B2
Abstract:
The present invention relates to a negative electrode having a carbon-based thin film formed on at least one surface of a lithium metal layer, and a lithium secondary battery including the same. According to the present invention, a carbon-based thin film formed on at least one surface of a lithium metal layer blocks side reactions caused by a direct contact between the lithium metal layer and an electrolyte as well as increasing a specific surface area of a negative electrode, and thereby suppresses lithium dendrite formation, and by obtaining current density distribution uniformly, enhances cycle performance, reduces an overvoltage to improve electrochemical performance of a lithium secondary battery.
