Lead –acid batteries can cover a wide range of requirements and may be further optimised for particular applications (Fig. 10). 5. Operational experience Lead–acid batteries have been used for energy storage in utility applications for many years but it hasonlybeen in recentyears that the demand for battery energy storage has increased.
whereas it is 12kg/kg for Li-ion batteries. For volatile organic compounds (VOC), carbon monoxide (CO), nitrogen oxides (NOx), particulate matter (PM) and sulfur oxides (SOx), emissions for Li-ion battery production are in all cases higher than for lead-acid battery production.
Over the past two decades, engineers and scientists have been exploring the applications of lead acid batteries in emerging devices such as hybrid electric vehicles and renewable energy storage; these applications necessitate operation under partial state of charge.
Considerable endeavors have been devoted to the development of advanced carbon-enhanced lead acid battery (i.e., lead-carbon battery) technologies.
