Pre-lithiated negative electrode and secondary battery comprising same

Disclosed is a pre-lithiated negative electrode comprising: a negative electrode current collector; and a negative electrode active material layer formed on at least one surface of the negative electrode current collector, in which the negative electrode active material layer includes a high capacity artificial graphite without a carbon coating, the negative electrode active material layer is pre-lithiated, and the lithium content of the pre-lithiated negative electrode is less than the lithium content of the pre-lithiated negative electrode when the pre-lithiated negative electrode is charged to 100%. The content of lithium embedded in the pre-lithiated negative electrode active material layer is 3% to 5%. 披露了一种预锂化负极，包括：负极集电器；以及形成在负极集电器的至少一个表面上的负极活性材料层，其中所述负极活性材料层包括无碳涂层的高容量人造石墨，所述负极活性材料层是经预锂化的，并且基于当预锂化负极充电至100％时嵌入的锂的含量，嵌入到经预锂化的负极活性材料层中的锂的含量为3％至5％。
