<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing an electrode for a nonaqueous electrolyte secondary battery, by which the pressing time for flattening a wound electrode body can be reduced. <P>SOLUTION: In a method for manufacturing a wound electrode body 30 of a lithium ion secondary battery 100, a positive electrode sheet 31, a negative electrode sheet 32 and a separator 35 are laminated, the positive electrode sheet 31, the negative electrode sheet 32 and the separator 35 which have been laminated are wound to form the wound electrode body 30, a phenol resin 40 is coated on the outermost periphery of the wound electrode body 30, and the wounding is pressed so as to be flattened, while the wound electrode body 30 on which the phenol resin 40 has been wound is heated at a predetermined temperature T1 equal to or above the curing temperature Tf at which the phenol resin 40 is cured. <P>COPYRIGHT: (C)2013,JPO&INPIT |
