NOVELTY - The nonaqueous electrolyte secondary battery having an internal resistance of 10 m Omega or less as an alternating-current impedance value of 1 kHz, comprises a metal outer container (1), a nonaqueous electrolyte contained in the container, a positive electrode contained in the container, a negative electrode contained in the container and having an active material for intercalating lithium ions at a potential of 0.4 V or more with respect to an electrode potential of lithium, a separator (7) interposed between the negative electrode and the positive electrode, and a negative electrode lead.    USE - The nonaqueous electrolyte secondary battery is useful in a battery module (claimed), and in vehicles such as a power-assisted bicycle, electric scooter, electric vehicle, hybrid vehicle and electric train.    ADVANTAGE - The nonaqueous electrolyte secondary battery exhibits enhanced energy density, overdischarge cycle performance, low internal resistance, high output density, high mechanical strength, electrochemical stability, chemical stability and corrosion resistance of materials for a long period in the conditions of high temperature, high humidity, vibration and quick charging.    DETAILED DESCRIPTION - The nonaqueous electrolyte secondary battery having an internal resistance of 10 m Omega or less as an alternating-current impedance value of 1 kHz, comprises a metal outer container (1), a nonaqueous electrolyte contained in the container, a positive electrode contained in the container, a negative electrode contained in the container and having an active material for intercalating lithium ions at a potential of 0.4 V or more with respect to an electrode potential of lithium, a separator (7) interposed between the negative electrode and the positive electrode, a negative electrode lead having a first end connected to the negative electrode, and a negative electrode terminal attached to the outer container so as to be connected electrically to a second end of the negative electrode lead. The negative electrode lead is made of aluminum or its alloy with a purity of 99.9 wt.% or more. The negative electrode terminal comprises a terminal body made of copper, iron and nickel, and a layer formed on the surface of the terminal body to which the second end of the negative electrode lead is connected. The active material of the negative electrode comprises titanium-containing oxide particles having an average diameter of 1 mu m or less. The negative electrode has a current collector composed of an aluminum foil or its with a purity of 99 wt.% or more. The outer container comprises a metal can (2), and a metal lid (3) bonded to an opening (4) of the metal can.
