A complex alloy of at least three phases comprising a composite alloy composed of a Si single phase and a Si-Al-M alloy phase, and a L phase offers a negative electrode material. M is an element selected from transition metals and metals of Groups 4 and 5, and L is In, Sn, Sb, Pb or Mg. The negative electrode material provides a lithium ion battery with a high capacity and long life. The material itself is highly conductive and increases the energy density per volume of a lithium ion battery. |
