METHOD FOR PRODUCING ELECTRODE PLATE FOR BATTERY

摘要

A production method of the present invention includes steps of: (a) obtaining a first electrode plate precursor 1 by applying an electrode active material onto at least one of surfaces of a long strip-shaped current collector so as to form an active material layer, (b) rolling an electrode plate precursor so that the active material layer has a predetermined thickness, and (c) obtaining plural strips of electrode plates by cutting the rolled electrode plate precursor to a desired width. In the step (a), non-application portions onto which an active material is not applied are formed on both edges of the electrode plate precursor in the width direction. The step (d) of removing the non-application portions is carried out simultaneously with the step (c). Accordingly, it is possible to improve production efficiency and reduce material losses by decreasing quality defects that occur in the step of rolling the electrode plate precursor.
