METHOD FOR MANUFACTURING BATTERY ELECTRODE PLATE

摘要

Provided is a method for manufacturing a battery electrode plate including: a step [a] which applies an electrode active material at least to one of the surfaces of a belt-shaped collector so as to obtain a first electrode precursor (1) having an active material layer; a step [b] which rolls the electrode plate precursor so as to make the active material layer have a predetermined thickness; and a step [c] which cuts the rolled electrode plate precursor into a desired width to obtain a plurality of belt-shaped electrode plates.  In the step [a], a non-material-applied portion to which the active material is not applied is formed at both ends in the width direction of the electrode plate precursor.  A step [d] for cutting off the non-active-material-applied portion is executed simultaneously with the step [c].  This reduces the quality defects generated in the step of rolling the electrode precursor, which in turn improves the production efficiency with a reduced material loss.
