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.

摘要： A battery pack includes at least a lithium ion secondary battery, a voltage sensor, and a control unit. The control unit controls discharge of the battery by a relatively high end-of-discharge voltage when the use frequency of the battery is relatively low during discharge of the battery. On the other hand, the control unit controls discharge of the battery by a relatively low end-of-discharge voltage when the use frequency of the battery is relatively high. Consequently, it is possible to prevent the utilizable capacity from decreasing more than a practical decrease in the capacity due to increase in the use frequency.
摘要翻译：电池组至少包括锂离子二次电池，电压传感器和控制单元。当电池放电期间电池的使用频率相对较低时，控制单元通过相对高的放电终止电压来控制电池的放电。另一方面，当电池的使用频率相对较高时，控制单元通过相对低的放电后电压来控制电池的放电。因此，由于使用频率的增加，可以防止可利用的容量比实际的容量减小更多。
