Currently, stationary energy-storage only accounts for a tiny fraction of the total sales of lead–acid batteries. Indeed the total installed capacity for stationary applications of lead–acid in 2010 (35 MW) was dwarfed by the installed capacity of sodium–sulfur batteries (315 MW), see Figure 13.13.
It should be noted that the lead–acid cell is able to operate effectively as an energy-storage device by virtue of three critical factors. First, contrary to thermodynamic expectations, the liberation of hydrogen from acids by lead takes place at only a negligible rate, i.e., there is a high hydrogen overpotential.
Hydrogen that is generated during the overcharging of lead–acid batteries that are housed in confined spaces may become an explosion risk. This hazard can be avoided by management of the charging process and by good ventilation. 13.4. Environmental Issues The main components of the lead–acid battery are listed in Table 13.1.
Of the 31 MJ of energy typically consumed in the production of a kilogram of lead–acid battery, about 9.2 MJ (30%) is associated with the manufacturing process. The balance is accounted for in materials production and recycling.
If a lead–acid cell is exposed to excessively high-rate charging, a point may be reached where the reactions that should convert lead sulfate back to active materials are unable to accommodate all of the charging current.
The lead–acid battery has undergone many developments since its invention, but these have involved modifications to the materials or design, rather than to the underlying chemistry. In all cases, lead dioxide (PbO 2) serves as the positive active-material, lead (Pb) as the negative active-material, and sulfuric acid (H 2 SO 4) as the electrolyte.
