Abstract
A method for manufacturing an electrode plate includes a first application step of applying conductive layer slurry containing fibrous carbon to a surface of a core made of metal foil, a second application step of applying active material mix layer slurry containing an active material to the conductive layer slurry before the conductive layer slurry dries, and a drying step of drying the conductive layer slurry and the active material mix layer slurry. The fibrous carbon contained in the conductive layer slurry has a fiber length-to-diameter ratio of 20:1 to 2,000:1. The amount of the fibrous carbon, contained in the conductive layer slurry applied to the core surface, per unit are of the core is 0.05 g/mto 0.20 g/mafter the first application step.
