Abstract
The present disclosure relates to a method for manufacturing a negative electrode for an all solid state secondary battery, including the steps of: (S1) preparing a preliminary negative electrode including: a current collector; and a negative electrode active material layer formed on at least one surface of the current collector, and containing a plurality of negative electrode active material particles and a solid electrolyte; (S2) disposing a lithium layer on the negative electrode active material layer; (S3) dipping the preliminary negative electrode having the lithium layer disposed thereon in an organic solvent; and (S4) removing the lithium layer. The present disclosure also relates to a negative electrode for an all solid state secondary battery obtained by the method. The negative electrode for an all solid state secondary battery provides improved initial efficiency and cycle characteristics.
