METHOD FOR MANUFACTURING NEGATIVE ELECTRODE, NEGATIVE ELECTRODE OBTAINED THEREFROM AND SECONDARY BATTERY INCLUDING THE SAME

A method for manufacturing a negative electrode, including the steps of preparing a negative electrode slurry including low-expansion natural graphite, a binder polymer, a conductive material and a dispersion medium; applying the negative electrode slurry to at least one surface of a negative electrode current collector, drying the coated negative electrode slurry, to form a preliminary negative electrode having a preliminary negative electrode active material layer; and pressing the preliminary negative electrode to obtain the negative electrode having a finished negative electrode active material layer. A difference between the specific surface area of the preliminary negative electrode active material layer before pressing and that of the finished negative electrode active material layer after pressing is 0.5 m/g to 1.0 m/g. A negative electrode obtained by the method and a secondary battery including the negative electrode are also disclosed.
