  "textContent": "The present invention relates to a method for pre-lithiation of a negative electrode for a secondary battery, for reducing the time required for pre-lithiation and reducing changes in volume of the electrode. The present invention comprises an electrolyte wetting step of immersing a negative electrode for a secondary battery in the electrolyte, and a pre-lithiation step of pre-lithiating the negative electrode, wherein the electrolyte wetting step includes a step of introducing the prepared negative electrode into an electrolyte bath containing the electrolyte, and a vacuum application step of removing bubbles and moisture in the negative electrode by applying a vacuum to the electrolyte bath in which the negative electrode is immersed.",
