Claim 8:
9. A method for preparing a prelithiated anode, comprising:
(a) a step of preparing an anode comprising an anode active material layer formed on the surface of one or both sides of a current collector; and
(b) a step of preparing a prelithiated anode by immersing the anode in a prelithiation solution comprising a lithium organic complex of an aromatic hydrocarbon derivative, of which at least one benzene ring has a non-hydrogen substitute,
wherein the aromatic hydrocarbon derivative is one or more selected from a group consisting of compounds represented by any of Chemical Formula 1 and Chemical Formula 2:, wherein
in Chemical Formula 1, each of R1 and R2, which are identical to or different from each other, is C1-C4 alkyl,
each of a and b is independently an integer from 0 to 2, wherein at least one is not 0,
if a is 2 or greater, two or more R1's are identical to or different from each other, and
if b is 2 or greater, two or more R2's are identical to or different from each other, and
in Chemical Formula 2,, each of R3 and R4, which are identical to or different from each other, is C1-C4 alkyl,
each of c and d is independently an integer from 0 to 2, wherein at least one is not 0,
if c is 2 or greater, two or more R3's are identical to or different from each other, and
if d is 2 or greater, two or more R4's are identical to or different from each other.
