<P>PROBLEM TO BE SOLVED: To provide a positive electrode plate for nonaqueous secondary battery in which breakage of the positive electrode plate is suppressed when winding and laminating the electrode plate using a current collector having a crystal grain with particle growth made by applying heat treatment which is used for an electrode group, and which has excellent safety when falling and crash, and to provide a nonaqueous secondary battery employing the same. <P>SOLUTION: The positive electrode plate for nonaqueous secondary battery is configured such that a positive electrode mixture layer 12 in which an active material consisting of at least lithium-contained compound oxide, a conductive material, and a binder are kneaded and dispersed by a dispersant is coated on the positive electrode current collector 13 to form a positive electrode mixture layer, which is then, pressed into a prescribed thickness, and is heat treated at a temperature at which the crystal grain 11 of the positive electrode current collector 13 is grown in particle. <P>COPYRIGHT: (C)2011,JPO&INPIT |
