PURPOSE:To restrict deformation of a negative pole following charge cycles, and provide a negative pole material having good cyclic characteristics in the case of a nonaqueous electrolyte secondary battery. CONSTITUTION:As a negative pole active material of a nonaqueous secondary battery composed of a positive pole 1 and a negative pole 4 capable of storing and emitting alkaline metal such as lithium, is used an Al-A-B (A is a rare soil metal, B is a transition metal) amorphous alloy having a very large viscosity and high strength. By using the Al-A-B (A is a rare soil metal, B is a transition metal) amorphous alloy as the negative pole active material, deformation of the negative pole by charge/discharge cycles can be restricted, thereby a nonaqueous electrolyte secondary battery having good cyclic characteristics can be obtained. |
