Abstract

A method of manufacturing an electrode includes: 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. In the firing process, the second electrode plate is heated at the second temperature while being transported by a roll-to-roll method.
