20090053593 | BATTERY - A battery capable of suppressing the swollenness and improving the capacity and the like is provided. The battery includes a spirally wound electrode body ( | 02-26-2009 |
20090098443 | BATTERY PACK AND METHOD FOR PRODUCING THE SAME - A battery pack includes a battery including a battery element covered with a packaging member, a battery protection circuit board, a covering material, and a rippable portion formed in a part of the covering material. The battery element includes a positive electrode and a negative electrode which are spirally wound or stacked through a separator. The covering material collectively covers the battery and the battery protection circuit board. The rippable portion rips open due to a gas generated from the battery in the event of an abnormal condition to form a gas release hole for releasing the gas outside the battery pack. | 04-16-2009 |
20090191448 | Battery Pack and Method For Producing The Same - A battery pack includes: a battery including a battery element covered with a packaging member, the battery element including a positive electrode and a negative electrode which are spirally wound together or stacked on one another through a separator; a protection circuit board for the battery; and a covering material collectively covering the battery and the protection circuit board. The covering material includes a shape-retaining polymer. The shape-retaining polymer contains an insulating curable polyurethane resin including polyol and polyisocyanate. | 07-30-2009 |
20090191456 | BATTERY PACK AND MANUFACTURING METHOD THEREFOR - A battery pack has a battery obtained by packing a battery element with a packing member. The battery element is formed by winding or laminating an anode and a cathode through separators. The battery pack includes frame member surrounding the packing member packing the battery element and a coating layer constituted of a curable resin formed on surfaces of the packing member which are surrounded and demarcated by the frame member. | 07-30-2009 |
20090202918 | POLYMER ELECTROLYTE AND BATTERY - A polymer electrolyte capable of obtaining superior discharge characteristics and a battery using it are provided. A cathode ( | 08-13-2009 |
20100310911 | BATTERY PACK - A battery pack includes a plurality of batteries, each including a battery element formed by winding or stacking a positive electrode and a negative electrode with a separator therebetween, and a packaging material packaging the battery element; a connecting member that electrically connects the batteries to form a battery group; a holding unit that holds the batteries together; a protection circuit substrate connected to the battery group; and an outer packaging member that integrally covers the battery group and the protection circuit substrate, the outer packaging member being formed by filling a space in a molding die housing the battery group and the protection circuit substrate with a resin and curing the resin at a temperature of 100° C. or less. | 12-09-2010 |
20110250475 | BATTERY PACK AND METHOD FOR MAKING SAME - A battery pack includes: a battery having a main surface; and a resin layer capable of being integrated with an armor member armoring the battery so that at least a part of the main surface of the battery is exposed and covering the main surface of the battery, wherein the resin layer is formed by curing a reaction curable resin having a viscosity of not less than 80 mPa·second to less than 1000 mPa·second and a thickness of the resin layer on the main surface of the battery ranges from 0.05 mm to smaller than 0.4 mm. | 10-13-2011 |
20120121944 | BATTERY PACK, METHOD OF MANUFACTURING BATTERY PACK, AND MOLD FOR MANUFACTURING BATTERY PACK - A battery pack includes a formed portion coating at least a portion of the outer surface of a battery or a plurality of battery packs with reaction-curable resin; and spacers having dimension-absorbing ability and attached to the rear surface of the formed portion. | 05-17-2012 |
20120183819 | BATTERY PACK, METHOD FOR MANUFACTURING BATTERY PACK, ELECTRONIC DEVICE, AND MOLDED PART - A battery pack includes a battery and a casing covering the battery and formed of a shape-memory resin. A portion or the entirety of the casing is deformed by heating at a predetermined temperature. The deformed casing returns to an original shape at the predetermined temperature or higher. | 07-19-2012 |
