Abstract
Disclosed is an electrode for secondary batteries including an electrode mix, which includes an electrode active material and a binder, coated on a current collector. More particularly, the electrode includes a first electrode mix layer including a first binder, a glass transition temperature (Tg) of which is lower than that of a second binder, and an electrode active material, and coated on the current collector; and a second electrode mix layer including the second binder, a glass transition temperature (Tg) of which is higher than that of the first binder, and an electrode active material, and coated on the first electrode mix layer.
