Abstract
A method for pre-lithiating a silicon oxide negative electrode for a secondary battery, specifically a method for pre-lithiation by immersing the silicon oxide negative electrode in an electrolytic solution for wetting, and by applying pressure while a lithium metal is in direct contact with the wetted silicon oxide negative electrode. The silicon oxide negative electrode for a secondary battery manufactured through pre-lithiation provided in the present disclosure has improved initial irreversibility, and a secondary battery manufactured using such a silicon oxide negative electrode for a secondary battery has excellent charge/discharge efficiency.
