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 lithium ion secondary battery including a flat-plate electrode assembly which is configured by stacking the positive electrode, the separator, and the negative electrode in the thickness direction thereof, each of the positive electrode and the negative electrode includes a current collector and an active material layer. Each of the current collector includes a substantially rectangular current collector body, a heat radiating portion, and a lead portion, and the heat radiating portions are projected toward the outside of the electrode assembly so as not to overlap with each other in the thickness direction of the electrode assembly. In this way, heat caused inside the lithium ion secondary battery can be diffused efficiently to the outside, and safety of the lithium ion secondary battery can be further increased, without complicating the battery structure and decreasing mechanical strength of the battery.
