Method for manufacturing electrode

A method of manufacturing an electrode, the method comprising:

• an application process of applying mixture slurry containing a dispersion medium and an electrode mixture that contains an electrode active material onto a surface of a core material sheet to form a first electrode plate having a wet coating film;
• a drying process of heating the first electrode plate at a first temperature to volatilize the dispersion medium from the wet coating film to form a second electrode plate having a dry coating film;
• and
• a firing process of heating the second electrode plate at a second temperature higher than the first temperature to obtain a fired third electrode plate,
• wherein, in the firing process, one surface of the second electrode plate is transported to a peripheral surface of a first firing roll and heated, and then, another surface of the second electrode plate is transported to a peripheral surface of a second firing roll and heated.
