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.

摘要： A method for manufacturing a negative electrode for a non-aqueous electrolyte secondary battery is provided. A negative electrode precursor of the non-aqueous electrolyte secondary battery is allowed to absorb lithium ions, the negative electrode precursor includes a current collector and an active material layer formed on the current collector. The precursor is provided with an exposed portion of the current collector. In this method, a negative electrode active material layer is allowed to absorb lithium ions by electrolysis in the non-aqueous electrolyte solution. At this time, by measuring a potential of a portion immersed in the non-aqueous electrolyte solution, the exposed portion is detected and an electric current of the electrolysis is controlled. Thereby, the deposition of lithium metal on the exposed portion is suppressed.
