A method for manufacturing a negative electrode for a lithium secondary battery is provided in which the method is capable of effectively performing pre-lithiation. While a negative electrode is compressed with a press, a lithium alloy layer is formed on a portion in contact with a negative electrode active material layer of upper and lower plates of the press, and a negative electrode tab is electrically connected to the press through a connection part respectively disposed on the upper and lower plates of the press, and thus, it is possible to manufacture a negative electrode for a lithium secondary battery in which the pre-lithiation of the negative electrode may be performed at time of compression even without a separate pre-lithiation process.
