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： In a driving device that includes a mechanical oil pump operated by power of an engine and a motor oil pump EOP operated by power of a motor, provided in parallel with each other, and check valves on discharge sides of the pumps, and pumps oil from any of the pumps and supplies the oil to a clutch included in a transmission, a through hole 68a for releasing air that communicates with a discharge port 68 is formed in a case 61 of the mechanical oil pump MOP. This allows air trapped in when driving of the mechanical oil pump MOP is started along with a start of the engine to be quickly discharged to quickly increase internal pressure to pressure required for opening the check valve, and thus oil can be supplied to the clutch of the transmission via the check valve to quickly operate the clutch.
