<P>PROBLEM TO BE SOLVED: To provide a negative electrode of a lithium secondary battery, capable of achieving charge/discharge cycle characteristics more excellent than conventional arts. <P>SOLUTION: A negative electrode of a lithium secondary battery includes a collector layer and an active material layer laminated on the collector layer. When the active material layer has a layer comprising Ni<SB POS="POST">x</SB>Cu<SB POS="POST">6-x</SB>Sn<SB POS="POST">5</SB>(in the formula, x is 0.30-2.0), the negative electrode exhibits excellent charge/discharge cycle characteristics. <P>COPYRIGHT: (C)2013,JPO&INPIT |
