20160028071 | Light-Weight Bipolar Valve Regulated Lead Acid Batteries and Method - Light-weight VRLA batteries comprise a thin lead substrate that is supported by non-conductive, preferably plastic frames that provide structural stability to accommodate stress and strain in the bipole assembly. In particularly preferred batteries, the plastic frames are laser welded together and phantom grids and electrode materials are coupled to the respective sides of the lead substrate. Where the phantom grid is an ultra-thin lead grid, the lead grid is preferably configured to provide a corrosion reserve of less than 10 charge-discharge cycles and the bipole assembly is charged in an in-tank formation process. Where the phantom grid is a non-conductive grid, the lead grid is preferably a plastic grid and the bipole assembly is charged in an in-container formation process. Consequently, weight, volume, and production costs are significantly reduced while specific energy is substantially increased. | 01-28-2016 |
20150349316 | Lead Acid Battery Having A Strap Molding Well - A lead acid battery has a housing having a plurality of adjacently positioned battery plate receiving compartments. A cell of battery plates is positioned in each battery plate receiving compartment. Each cell has a plurality of positive plates, each having a positive lug, and a plurality of negative plates interleaved with the positive plates, each having a negative lug. A mold positioned on a top edge of each group of battery plates, and has two strap molding wells, each having a lead receiving space, a well base, and a plurality of lug receiving openings positioned in the well base. The positive lugs of the cell extend through the lug receiving openings in one of the strap molding wells, and the negative lugs of the cell extend through the lug receiving openings in the other strap molding well. | 12-03-2015 |
20150021991 | Management Of Battery Capacity - Disclosed is a battery cell system, which provides regulation service to the grid, as well as the battery being used as part of an uninterruptible power supply (UPS). Part of the capacity of the storage batteries may be used for regulation service, while maintaining a reserve of battery capacity to provide the UPS supply if required. An advantage is that the battery installation can be more effectively monitored as it is more regularly being charged and discharged. | 01-22-2015 |
20140072868 | Composite Current Collector and Methods Therefor - Contemplated lead acid batteries include a monolithic lead/lead alloy composite foil that is preferably formed by cladding mechanically unstressed lead and lead alloy foils. In such batteries, a light-weight non-conductive grid is placed onto the lead alloy side of the composite foil, which is most preferably pre-treated with a lead-containing adhesive that improves retention of the grid and improves retention and intimate electric contact of the positive active material. | 03-13-2014 |
