20080318120 | Power storage unit - A power storage unit has: a plurality of power storage modules each constituted of a power generation element and a power-generation-element-case containing the power generation element and disposed adjacent to each other, and a case containing the power storage modules and an insulative fluid. At least one groove is formed at the power-generation-element-case of each power storage module such that the power-generation-element-case breaks at the groove in response to an excessive increase in the pressure in the power-generation-element-case. The groove is formed in a portion of the power-generation-element-case that does not face any other power storage module. | 12-25-2008 |

20100003598 | ELECTRODE FOR A POWER STORING APPARATUS AND POWER STORING APPARATUS PROVIDED WITH THAT ELECTRODE - An electrode for a power storing apparatus has a collector and a plurality of electrode patterns formed on at least one surface of the collector. An electrode pattern in a region where heat is radiated less than in other region, from among the plurality of electrode patterns, has a lower formation density than an electrode pattern in the other region. | 01-07-2010 |
20100009250 | SECONDARY BATTERY - A secondary battery includes: a battery module including an electrolyte layer in a form of a plate, a positive electrode disposed on a first main surface of the electrolyte layer and containing a positive electrode active material, and a negative electrode disposed on a second main surface of the electrolyte layer and containing a negative electrode active material; and a conductive layer provided between battery modules, the secondary battery having more than one battery module and more than one conductive layer stacked in layers, wherein the positive electrode active material and the negative electrode active material are set in concentration in accordance with a temperature distribution in the secondary battery. | 01-14-2010 |
20100035157 | ELECTRICAL STORAGE DEVICE - An electrical storage device has a solid electrolyte layer; and electrode assemblies stacked with the solid electrolyte layer interposed therebetween and each having a current collector on which a plurality of electrode parts are formed. A part of the solid electrolyte layer is located between successive electrode parts in a direction perpendicular to the stacking direction on at least one of successive electrode assemblies in the stacking direction. | 02-11-2010 |
20100055547 | POWER STORAGE DEVICE - A power supply device in which a plurality of power supplying bodies are stacked is provided with a plurality of holes that extend from one end side to the other end side in the stacking direction of the power supply device and through which coolant flows. The power supply device is also provided with a guide portion that leads coolant that has passed through a first hole which is provided in a first region of the power supply device into a second hole which is provided in a second region of the power supply device which radiates heat better than the first region does. | 03-04-2010 |
20100062321 | COOLING APPARATUS AND VEHICLE - A cooling apparatus includes a case which houses a power storage unit, a heat transfer member which can contact with the case, and a driving mechanism which relatively moves the case and the heat transfer member and operates between a first state in which the case and the heat transfer member is in contacting state and a second state in which the case and the heat transfer member is in non-contacting state. | 03-11-2010 |
20100163325 | ASSEMBLED BATTERY AND VEHICLE - In an assembled battery used as a power source of a vehicle, a negative electrode collector plate and a positive electrode collector plate are arranged at every two bipolar secondary batteries adjacent in a stacking direction among a plurality of bipolar electrodes. The negative electrode collector plate and the positive electrode collector plate also function as heat radiating members, as a cooling medium is caused to flow therein. It becomes unnecessary to connect a cooling tab to the positive electrode collector plate (or the negative electrode collector plate) to cool the assembled battery and, therefore, no portion protrudes from the positive electrode collector plate (or the negative electrode collector plate) of the assembled battery. Thus, the inside of assembled battery can be cooled while reducing the size of the assembled battery. | 07-01-2010 |

20110212354 | POWER STORAGE APPARATUS - A power storage apparatus has a power storage element including an electrolyte layer and a plurality of electrode elements stacked with the electrolyte layer interposed between them, and a case accommodating the power storage element and a heat exchange medium for use in heat exchange with the power storage element. The power storage element has an opening portion passing through the power storage element and extending from one end face to the other end face of the power storage element in a stacking direction. A top-face portion of the case located above the power storage element includes an inclined surface inclined with respect to the stacking direction in the power storage element. | 09-01-2011 |
20120196180 | ELECTRODE FOR ELECTRIC STORAGE DEVICE AND ELECTRIC STORAGE DEVICE - An electrode is used for an electric storage device that includes plural electrodes that are stacked such that an ion-conductive layer is disposed between each pair of the electrodes. Each of the plural electrodes includes a current collector, and an electrode layer, formed on the current collector, which contains an active material. The configuration of the electrode layer (for example, the amount of the active material) varies according to the position in the electrode layer such that a current density in a first region of the electrode, where heat radiation performance is lower than the heat radiation performance in a second region of the electrode, is lower than the current density in the second region of the electrode. | 08-02-2012 |
