摘要： A portable electronic device of the present invention includes a package, an electronic device body, a battery housing portion including a battery fitting portion for fitting a secondary battery therein, a foaming agent-containing layer provided on a surface of the battery housing portion, and a secondary battery to be fitted in the battery fitting portion. The foaming agent-containing layer is normally thin and, in the event of the battery generating heat, the layer turns into a thicker foamed layer which exhibits superior thermal insulation properties. Thus, it is possible to provide a portable electronic device having the degree of freedom in design for size and thickness reduction achieved at a high level, while offering high-level safety and reliability.

摘要： In a charge/discharge method for a positive-electrode active material in a lithium secondary battery, the lithium secondary battery includes a positive electrode containing a positive-electrode active material capable of occluding and releasing lithium ions, a negative electrode containing a negative-electrode active material capable of occluding and releasing lithium ions, a separator located between the positive electrode and the negative electrode, and an electrolyte having a lithium ion conductivity; and the positive-electrode active material contains a nickel-type lithium-containing complex oxide. The positive electrode, which has been charged, is discharged until having a first potential VDp1 which is no less than 2.7 V and no more than 3.4 V on a lithium metal basis, and then the discharge is finished. Owing to this, the charge/discharge cycle life can be improved while the capacity of the lithium secondary battery is secured.

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。

摘要： A lithium secondary battery according to the present invention includes: a positive electrode having a positive-electrode active material capable of occluding and releasing lithium ions; a negative electrode having a negative-electrode active material capable of occluding and releasing lithium ions; a separator interposed between the positive electrode and the negative electrode; and an electrolyte having lithium-ion conductivity. The positive-electrode active material contains a nickel-type lithium-containing complex oxide. The negative-electrode active material contains a graphite-type material having a reversible capacity of 350 mAh/g or more and an irreversible capacity of 30 mAh/g or less. A ratio Qc/Qa between an irreversible capacity Qc per unit area in a portion of the positive electrode that opposes the negative electrode and an irreversible capacity Qa per unit area in a portion of the negative electrode that opposes the positive electrode is equal to or greater than 0.50 but less than 1.13. As a result, the charge-discharge cycle characteristics can be improved while ensuring a high capacity.

摘要： A battery pack 1 of the present invention includes: a plurality of lithium ion secondary batteries 10 electrically connected together in series, in parallel, or in series-parallel combination; a tray 11; and a housing 12. The lithium ion secondary batteries 10 each include an electrode assembly containing an alloy-based negative electrode active material serving as a negative electrode active material, and each have a sealed surface 10a. The lithium ion secondary battery 10 is mounted on the tray. The housing 12 accommodates the tray 11 with the lithium ion secondary battery 10 mounted thereon. Even if high-temperature contents are produced in the interior of the lithium ion secondary battery 10 in the event of internal short circuiting or overcharging, this configuration prevents the high-temperature contents from leaking out of the batter pack 1, and thus improves the safety of the battery pack 1.
