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 battery assembly having an improved case, simplifying manufacture, includes a tubular case having an internal space, an open end, a closed end, a cell element in the internal space of the case, and a cap closing the open end of the case, wherein the internal sectional dimension of the case is largest at the open end and smallest as the closed end while the external dimensions of the case are uniform. The change in internal dimensions may be provided by a tapering thickness of the case. Because of the tapered opening within the case, the cell element is easily inserted into the case.
