20080254348 | BATTERY PACK - A battery pack includes a non-aqueous electrolyte secondary battery, a rigid covering member, and a protection circuit board. The secondary battery includes a battery element and a flexible covering member formed of a first laminated film composed of a first heat-bonding layer, a first metal layer, and a first outer covering layer laminated successively. The flexible covering member is sealed along around the battery element while leaving electrode terminals of the positive and negative electrodes extended outside the battery element. The rigid covering member is formed of a second laminated film composed of a second heat-bonding layer, a second metal layer, and a second outer covering layer laminated successively. The flexible covering member and the rigid covering member are bonded with an adhesive strength equal to or higher than atmospheric pressure and with a peel strength equal to or lower than a breaking strength of the flexible covering member. | 10-16-2008 |
20090098416 | BATTERY PACK - A battery pack includes a non-aqueous electrolyte secondary battery, a rigid covering member, and a protection circuit board. The secondary battery includes a battery element and a flexible covering member formed of a first laminated film composed of a first heat-bonding layer, a first metal layer, and a first outer covering layer which are laminated successively. The flexible covering material is sealed along around the battery element while leaving electrode terminals of the positive and negative electrodes extended outside the battery element. The rigid covering member covers the non-aqueous electrolyte secondary battery together with the flexible covering member, and is formed of a second laminated film composed of a second heat-bonding layer, a second metal layer, and a second outer covering layer which are laminated successively. The flexible covering member and the rigid covering member are bonded by melting the second heat-bonding layer without melting the first outer covering layer. | 04-16-2009 |
20120276443 | CELL - A cell in which thermal welding of a laminate packaging is performed so that the thickness of a thermal welded portion including an electrode terminal is larger than that of a thermal welded portion including no electrode terminal. | 11-01-2012 |
20130059192 | SEPARATOR AND NONAQUEOUS ELECTROLYTE BATTERY - A separator is provided. The separator includes a base layer and a surface layer, wherein the surface layer is on at least one side of the base layer, and wherein the surface layer is structured so as to collapse at time of charging to prevent damage to a negative electrode due to expansion thereof. A battery including the separator is also provided. An electric device, an electric vehicle, and an electrical storage device including the battery are further provided. | 03-07-2013 |
20140329122 | CELL - A cell in which thermal welding of a laminate packaging is performed so that the thickness of a thermal welded portion including an electrode terminal is larger than that of a thermal welded portion including no electrode terminal. | 11-06-2014 |
20140342204 | EXTERNAL PACKAGING MATERIAL FOR BATTERY DEVICE, NONAQUEOUS ELECTROLYTE SECONDARY BATTERY USING THE SAME, AND BATTERY PACK - An external packaging material for covering a battery device is provided. The packaging material includes a laminated film having a laminated structure having two or more resin film layers stacked. In the external packaging material, the laminated structure has no metallic foil, and at least one layer in the resin film layers contains a moisture absorbing material. | 11-20-2014 |
