INTERMITTENTLY COATED BATTERY ELECTRODE MANUFACTURING METHOD

摘要

To provide an intermittently coated battery electrode manufacturing method capable of preventing a positional displacement from occurring between a first surface of a collector and a second surface opposed to the first surface.;An intermittently coated battery electrode manufacturing method includes: forming, at a part of a strip-shaped collector where an active material is not coated, a front end indicator indicating a front end of the active material to be intermittently coated on the collector; performing coating of the active material on a first surface of the collector based on a detection signal of the front end indicator to form an intermittent coating layer; and starting coating of the intermittent coating layer on a second surface opposite to the first surface based on the detection signal of the same front end indicator as that used for forming the active material coating layer on the first surface.
