20110200855 | SECONDARY BATTERY; SOLAR POWER GENERATION SYSTEM, WIND POWER GENERATION SYSTEM, AND VEHICLE PROVIDED THERWITH; AND METHOD FOR FABRICATION OF A SECONDARY BATTERY - A secondary battery with improved life characteristics is provided. The secondary battery (lithium-ion secondary battery) has: an electrode assembly including positive electrodes and negative electrodes; and a package container for housing the electrode assembly along with non-aqueous electrolyte liquid. The package container includes a package can for housing the electrode assembly and a sealing plate sealing the opening of the package can. On the sealing plate, an elevated portion is formed that projects toward the electrode assembly and has, on the side opposite from the electrode assembly, a cavity portion for storing refill non-aqueous electrolyte liquid. The elevated portion has a hole for feeding the refill non-aqueous electrolyte liquid stored in the cavity portion toward the electrode assembly. The hole is sealed with a sealing stopper formed of a resin material letting the refill non-aqueous electrolyte liquid leak toward the electrode assembly. | 08-18-2011 |
