Abstract
The present disclosure relates to a binder for an anode of a secondary battery, an anode for a secondary battery and a secondary battery, wherein the binder comprises a binder particle comprises a copolymer core particle containing a repeating unit derived from an isoprene-based monomer; and a copolymer shell located on the surface of the core particle and containing a repeating unit derived from a butadiene-based monomer. Specifically, the present disclosure is for the purpose of improving the binder applied to the anode of the secondary battery, thereby minimizing the change in volume of the anode and the secondary battery and minimizing the decrease in capacity while increasing the energy density.
