ABSTRACT:
A nonaqueous electrolyte secondary battery, having an internal resistance of 10 mΩ or less as an alternating-current impedance value of 1 kHz, comprises a metal outer container, a nonaqueous electrolyte contained in the container, a positive electrode contained in the container, a negative electrode contained in the container, a separator interposed between the negative electrode and the positive electrode, a negative electrode lead having one end connected to the negative electrode, and a negative electrode terminal attached to the outer container so as to be connected electrically to the other end of the negative electrode lead, at least the surface of the negative electrode terminal which is connected to the negative electrode lead being formed of aluminum alloy with an aluminum purity of less than 99 wt. % containing at least one metal selected from the group consisting of Mg, Cr, Mn, Cu, Si, Fe and Ni.
