Abstract
A negative electrode active material for a secondary battery contains an aluminum alloy. The internal structure of the aluminum alloy has a crystalline aluminum phase in a magnesium-supersaturated solid solution state, and an amorphous aluminum phase. The amorphous aluminum phase is dispersed in the crystalline aluminum phase in the magnesium-supersaturated solid solution state. Each of these phases has a columnar shape. The magnesium content of the aluminum alloy preferably is greater than 22 at % and less than 35 at %, and more preferably, lies within a range of 25±2 at %.
