Abstract: A negative electrode includes a metal foil and a negative electrode active material layer coated on the metal foil. The upper and lower portions of the negative electrode are coated with a binder. The negative electrode has an excellent adhesion to the separator, thereby preventing folding of a separator when manufacturing a stack cell. A method of preparing the negative electrode which minimizes reduction in a manufacturing yield and occurrence of accidents due to low voltage defects is also provided. A secondary battery including the negative electrode, and a method of making the secondary battery, are also provided.
