1. An apparatus for manufacturing an electrode for a secondary battery comprising:
a roller-shaped unwinder in which a sheet-shaped current collector containing copper is wound;
a transfer part configured for continuously transferring the sheet-shaped current collector;
a heating part configured for heating the sheet-shaped current collector transferred from the unwinder at a temperature of 120° C. to 150° C. for a time (M) satisfying the following Equation 1; and
a coating part, disposed after the heating part in a moving direction of the sheet-shaped current collector, configured for coating an electrode active material slurry onto at least one surface of the heated sheet-shaped current collector, and
a drying part configured to form an electrode mixture on the at least one surface of the sheet-shaped current collector by drying the coated electrode active material slurry;
wherein, D is a heating temperature (° C.), and
M is a heating time (minutes)
wherein the coating part is a coating die, a coating roll, or a slide-slot.
