Lead–acid batteries have been used for energy storage in utility applications for many years but it has only been in recent years that the demand for battery energy storage has increased.
Lead–acid batteries may be flooded or sealed valve-regulated (VRLA) types and the grids may be in the form of flat pasted plates or tubular plates. The various constructions have different technical performance and can be adapted to particular duty cycles. Batteries with tubular plates offer long deep cycle lives.
Improvements to lead battery technology have increased cycle life both in deep and shallow cycle applications. Li-ion and other battery types used for energy storage will be discussed to show that lead batteries are technically and economically effective. The sustainability of lead batteries is superior to other battery types.
Safety needs to be considered for all energy storage installations. Lead batteries provide a safe system with an aqueous electrolyte and active materials that are not flammable. In a fire, the battery cases will burn but the risk of this is low, especially if flame retardant materials are specified.
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.
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.

Live ChatBattery lifetime could be increased out 20°C or slightly below is ideal for Lithium-Ion batteries. If a battery operates at 30°C instead of a more mod rate lower room temperature, lifetime is reduced by 20 percent. At 40°C, the losses in lifetime can be near 40 percent and if batteries are charged and discharged at 45°C, the
Live ChatLead–acid batteries are easily broken so that lead-containing components may be separated from plastic containers and acid, all of which can be recovered. Almost complete recovery and re-use of materials can be achieved with a relatively low energy input to the processes while lead emissions are maintained within the low limits required by ...
