Abstract
A lead acid electric storage battery uses conventional lead-acid secondary battery chemistry. The battery may be a sealed battery, an unsealed battery or a conventional multi-cellbattery. It has 12 to 25 cells in a single case. The case is less than 12 inches long and may be less than 6 inches long. The battery has a set of positive battery grids (plates) which are constructed with a core of thin titanium expanded metal having a thickness preferably, for start batteries etc. in the range 0.1 mm to 0.7 mm and most preferably 0.2 mm to 0.4 mm. The grid cores are of a titanium alloy containing a platinum group metal. The cores are coated with hot melt dip lead and are not lead electroplated. The grid cores expand and contract, with temperature changes, much less than conventional lead grids.
