  • Patent number: 11664485
    Abstract: A method for manufacturing a lithium secondary battery including a pre-lithiated negative electrode. A composite of lithium and a negative electrode active material is formed through a lamination process which is a process of manufacturing a battery. In the case of the lithium secondary battery to which the negative electrode having the composite formed by lithium and the negative electrode active material is applied, when the battery starts to operate, the negative electrode active material is pre-lithiated, and thus the charging/discharging process proceeds in the state where the lithium alloy is already formed on the negative electrode, thereby showing an effect of reducing initial irreversible phases.
