POSITIVE ELECTRODE AND POSITIVE ELECTRODE ACTIVE MATERIAL PLATE FOR LITHIUM SECONDARY BATTERY, AND METHODS FOR MANUFACTURING POSITIVE ELECTRODE AND POSITIVE ELECTRODE ACTIVE MATERIAL PLATE FOR LITHIUM SECONDARY BATTERY

摘要

The present invention relates to a positive electrode and a positive electrode active material plate for a lithium secondary battery, and methods for manufacturing the positive electrode and the positive electrode active material plate. The present invention is characterized in that grooves, which are configured of recessed sections, and have irregular shapes (for instance, irregular cell shapes) in planar view, are formed on the main surface of the positive electrode active material plate.
