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 negative electrode including a negative electrode current collector, first protrusions on a surface of the negative electrode current collector, a separation-stopping area on at least a part of a surface of each first protrusion, and a negative electrode active material layer including a negative electrode active material and formed on at least a top face of the first protrusion. This structure suppresses the separation of the negative electrode active material layer from the negative electrode current collector, the degradation of the current collecting ability, and the deformation of the negative electrode itself. A lithium ion secondary battery including this negative electrode has a high battery capacity, a high energy density, and an excellent charge/discharge cycle characteristic, and is capable of stably maintaining a high power over an extended period of time.

摘要： The present invention relates to a current collector including a base portion with a flat face, primary projections projecting from the flat face, and secondary projections projecting from the top of the primary projections. The present invention also relates to a current collector including a base portion with a flat face and primary projections projecting from the flat face, wherein the roughening rate of the top of the primary projections is 3 to 20. By using such a current collector, separation of the active material from the current collector can be inhibited when using an active material that has a high capacity but undergoes a large expansion at the time of lithium ion absorption.
