The present invention relates to a multilayer electrolyte cell, a secondary battery including the multilayer electrolyte cell, and a manufacturing method thereof, and more particularly, to a multilayer electrolyte cell, in which electrolytes are configured in multiple layers by stacking polymer coating layers containing ceramic solid electrolytes and liquid electrolytes including an ionic liquid in a porous structure base, a secondary battery including the multilayer electrolyte cell, and a manufacturing method thereof.

Multilayer electrolyte cell, secondary battery comprising multilayer electrolyte cell and manufacturing method therefor

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.

Electrode having enhanced adhesion for lithium secondary batteries
