An electrochemical device that can transform electrical energy into stored chemical energy and by reversing the process, release energy again. See Secondary battery.
The charge state of an automotive battery can be determined by measuring the acid density in kg/l. This is done using an acid siphon. The following characteristic factors apply: Acid density 1.28 kg/l: battery is fully charged. Acid density 1.20 kg/l: battery is half charged. Acid density 1.10 kg/l: battery is empty.
An inorganic additive for negative lead masses (BaSO4).
Lead oxide for active lead masses which is produced by means of a thermal process (Barton reactor) using liquid lead and atmospheric oxygen.
Production of a battery component (e.g. grid) by pouring a liquid lead alloy into a casting mold.
Chemical element (Cd) that belongs to the heavy metals. In battery technology, cadmium, cadmium oxides and cadmium hydroxide are used in the cadmium electrodes found in nickel-cadmium accumulators and in normal elements.
