| 20090154064 | Lithium ion capacitor - A lithium ion capacitor including a positive electrode, a negative electrode, and an aprotic organic solvent solution of a lithium salt as an electrolytic solution. The positive electrode active material is capable of reversibly supporting lithium ions and/or anions, the negative electrode active material is capable of reversibly supporting lithium ions and anions, and the potentials of the positive electrode and the negative electrode are at most 2.0 V after the positive electrode and the negative electrode are short-circuited. The positive electrode and the negative electrode are alternately laminated with a separator interposed therebetween to constitute an electrode unit, the cell is constituted by at least two such electrode units, lithium metal is disposed between the electrode units, and lithium ions are preliminarily supported by the negative electrode and/or the positive electrode by electrochemical contact of the lithium metal with the negative electrode and/or the positive electrode. | 06-18-2009 |

| 20090214955 | ELECTRIC STORAGE DEVICE, ELECTRODE, METHOD FOR FABRICATING ELECTRODE, AND MANAGEMENT METHOD - A mixture layer for an electrode is formed on a punched current collector. For example, the mixture layer is made of an active material, conductive assistant, binder, and the like. The mixture layer having the structure described above is formed into a slurry, for example, and applied onto the current collector. The applied mixture layer is dried to fabricate an electrode. The thus formed electrode is used to assemble an electric storage device. Upon the assembly, lithium ions are pre-doped into a negative electrode. The pre-doping time is determined according to air permeability of the electrodes. | 08-27-2009 |
| 20090242507 | MANUFACTURING PROCESS OF ELECTRODE - A resist layer is formed over one surface of a current-collector material, while a resist layer having a predetermined pattern is formed on the other surface of the current-collector material. Through-holes are formed on the current-collector material through an etching process. An electrode slurry is applied onto the current-collector material formed with the through-holes without removing the resist layers. Specifically, since the through-holes are closed by the resist layer, the electrode slurry does not pass through the through-holes to leak out. Therefore, the current-collector material can be conveyed in the horizontal direction, whereby the productivity of an electrode can be enhanced. The resist layers are made of PVdF, and the resist layers are removed in a heating and drying step in which the PVdF is dissolved. | 10-01-2009 |

| 20100035150 | ELECTRIC STORAGE DEVICE - An electrode laminate unit of an electric storage device includes positive electrodes, negative electrodes and a lithium electrode connected to the negative electrode. When an electrolyte solution is injected into the electric storage device, lithium ions are emitted from the lithium electrode to the negative electrode. A positive and a negative electrode current collector have through-holes that guide the lithium ions in the laminating direction. The aperture ratio of the through-holes at the edge parts where the electrolyte solution is easy to be permeated is set to be smaller than the aperture ratio at central parts in order to suppress the permeation. Thus, the distribution of the electrolyte solution is made uniform, whereby the doping amount is made uniform. | 02-11-2010 |
