<P>PROBLEM TO BE SOLVED: To prevent deformation of a negative electrode attendant on repeating of charge discharge, suppress deterioration of contact between a negative electrode material and a negative current collector caused by charge/discharge, and enhance charge/discharge cycle characteristics in a lithium secondary battery using the negative electrode for the lithium secondary battery formed by attaching the negative electrode material on the surface of the negative current collector. <P>SOLUTION: The negative electrode 13 for the lithium secondary battery is formed by attaching the negative electrode material which is alloyed with lithium on the negative current collector 13a having a proportional limit of 2.0 N/mm or more. The negative electrode is used in the lithium secondary battery. <P>COPYRIGHT: (C)2008,JPO&INPIT |
