For comparing devices in practice, the values in Wh or W max are divided by the volume or weight of the storage unit. Lead acid batteries have an energy density of 30 Wh/kg. The figures above were taken from Wikipedia. The figure at the left describes the energy density per weight as a function of the energy density per volume.
The term “battery acid” refers to the electrolyte used in batteries. For lead acid batteries this is sulfuric acid (H 2 SO 4). Sulfuric acid is colorless, odorless, and strongly acidic. Why measure the density / specific gravity of battery acid? Knowing the specific gravity of the electrolyte in batteries gives insight into the level of charge.
For lead-acid batteries, the specific gravity of a fully charged and healthy battery should be between 1.265 and 1.299. If the specific gravity is below this range, it indicates that the battery is not fully charged or may have some other issues that need to be addressed.
The lead acid battery is traditionally the most commonly used battery for storing energy. It is already described extensively in Chapter 6 via the examples therein and briefly repeated here. A lead acid battery has current collectors consisting of lead. The anode consists only of this, whereas the anode needs to have a layer of lead oxide, PbO 2.
The electrolyte in a lead-acid battery is sulfuric acid, which acts as a conductor for the flow of electrons between the lead plates. When the battery is charged, the sulfuric acid reacts with the lead plates to form lead sulfate and water.
