Anode manufacturing method, anode, and secondary battery comprising same

Abstract

A manufacturing method of a negative electrode including steps of preparing a preliminary negative electrode slurry including a negative electrode active material and a conductive material; adding an acid to the preliminary negative electrode slurry and mixing to form a negative electrode slurry; applying the negative electrode slurry on at least one surface of a current collector and performing a first drying and rolling the slurry to form a negative electrode active material layer; and performing a second drying of the current collector on which the negative electrode active material layer is formed. The negative electrode active material includes silicon-containing particles including silicon and a Li compound. A pH of the negative electrode slurry at 25° C. is 10 or more and less than 12.5.
