  • Publication number: 20240379940
    Abstract: In the case in which a lithium metal is used in order to increase the capacity of a lithium secondary battery, reversibility of charging and discharging is reduced due to dendrite, etc. A lithium metal having LiF deposited thereon exhibits high stability, whereby reversibility of charging and discharging is increased. In addition, in the case in which LiF is deposited, the lithium metal, which is a negative electrode material, is not consumed, and the shape of a lithium metal electrode is not greatly changed.
