Abstract
The present invention provides a negative electrode for a lithium secondary battery and a lithium secondary battery having the negative electrode. The negative electrode includes an aluminum alloy powder as an active material,wherein the alloy is substantially amorphous, and is represented by the formula AlxSiyMz, where M is at least one transition metal selected from the group consisting of Ni, Co, Cu, Fe, Cr and Mn;x, y and z are 40≦x≦80; 10≦y≦50 and 1≦z≦20, respectively, and x+y+z=100; andaverage particle diameter of the alloy is not greater than 50 &mgr;m.
