ABSTRACT:
An alloy for a negative electrode of a lithium secondary battery, comprising an Li-Ag-Te type alloy having an atomic ratio of Li:Ag:Te=15-120:1-20:0.001-2, an alloy for a negative electrode of a lithium secondary battery, comprising an Li-Ag-Te-(M1-M2) type alloy having an atomic ratio of Li:Ag:Te:M1:M2=15-120:1-20:0.001-2:1-50:1-30 wherein M1 is a 3A-5A group metal and M2 is a transition metal other than Ag, and a lithium secondary battery comprising a negative electrode composed of the above-mentioned alloy. According to the present invention, a negative electrode, wherein the growth of dendrite is suppressed, charge-discharge capacity is high, energy density is high and degradation due to repetitive charge-discharge is less, can be obtained. By the use of the negative electrode obtained in the present invention, moreover, a lithium secondary battery superior in charge-discharge cycle life, which has high energy density permitting long-term use, high electromotive force and high charge-discharge capacity, can be produced.
