Abstract
The negative electrode of this invention includes, as a negative electrode active material, substantially amorphous aluminum alloy in the form of a powder with an average particle size of 50 &mgr;m or less represented by a composition formula, Al100-xMx, in which M is at least one element selected from the group consisting of La, Y, Yb, Ce, Gd, Nd, Sm, Pr, Er, Ni, Co, Cu and Fe; and 1≦x≦20. Owing to this negative electrode, a lithium secondary battery having large discharge capacity and exhibiting very good charge-discharge cycle performance can be realized.
