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.
The term advanced or carbon-enhanced (LC) lead batteries is used because in addition to standard lead–acid batteries, in the last two decades, devices with an integral supercapacitor function have been developed.
This guide to IEC/EN standards aims to increase the awareness, understanding and use of valve regulated lead-acid batteries for stationary applications and to provide the ‘user’ with guidance in the preparation of a Purchasing Specification.
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.
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.
The lead–acid batteries are both tubular types, one flooded with lead-plated expanded copper mesh negative grids and the other a VRLA battery with gelled electrolyte. The flooded battery has a power capability of 1.2 MW and a capacity of 1.4 MWh and the VRLA battery a power capability of 0.8 MW and a capacity of 0.8 MWh.
Free leads are essentially non-oxidized lead particles with limited surface area. Limited surface area contributes to voltage loss on discharge of the battery.
