摘要： Provided is a binder for a secondary battery including a copolymer comprising specific repeating units, and when the binder for a secondary battery is applied to a negative electrode and a secondary battery, expansion of the negative electrode may be effectively suppressed. Furthermore, the binder for a secondary battery has improved adhesion to effectively suppress exfoliation and desorption of a negative electrode active material, thereby manufacturing a secondary battery having significantly improved charge/discharge cycle characteristics and battery performance by using the binder.
