Abstract
The present invention provides a polymeric composite binder which comprises binder polymer and a dispersant chemically bound to the surface of the binder polymer, as well as an electrode slurry, electrode and secondary battery using the same. By virtue of the dispersant chemically bound to the binder polymer surface, the present invention achieves an improvement in the stability of binder latex, an improvement in the dispersion and coating properties of electrode slurry, and also an improvement in the capacity and cycle characteristic of a battery.
