PURPOSE:To provide a non-aqueous electrolytic secondary battery excellent in charge/discharge cycle characteristics by letting a negative electrode be made of an Al-Si-Fe alloy which can store/emit lithium reversely. CONSTITUTION:The battery is equipped with a negative electrode composed of an Al-Si-Fe alloy capable of storing/emitting lithium reversely. The aforesaid negative electrode is preferably composed of Al-Si-Fe alloy powder, and of a mixture including carbonaceous material and binding agent. And moreover, it is preferable that the amount of Si shall be 1 to 50% the Al-Si-Fe alloy by weight, and the amount of Fe shall be 0.1 to 8% the aforesaid alloy by weight. |
