摘要： A positive electrode, a separator, and a negative electrode including an alloy-type negative electrode active material are stacked in this order, to form an electrode unit. Such electrode units are stacked with a separator interposed between each pair of the electrode units, to form a stacked electrode assembly. The stacked electrode assembly is fabricated, and the stacked electrode assembly is pressed during an initial charge and an initial discharge. As a result, a rate of increase of the thickness of the stacked electrode assembly due to a predetermined number of charge and discharge cycles becomes equal to or less than 10%. It is thus possible to obtain a lithium ion secondary battery having high capacity and high output, capable of maintaining battery performance such as charge/discharge cycle characteristics at a high level for a long time, and having long service life.
