Lead-Acid Batteries By 2000, most lead-acid, starting/lighten-ing/ignition (SLI) batteries produced in the Western world had made the transition from traditional lead-antimony alloy grids to lead-calcium-based alloys. The automobile require-ments for high cranking performance and maintenance-free batteries have accelerated the trend. Cost
As well demonstrated, the performance of the grid alloy, mainly the lead-antimony alloy and lead-calcium alloy [4, 5], plays an important role in the service life of lead-acid batteries. Lead-antimony alloys have occupied an important position for more than 100 years, which, however, cause water loss and affect battery life .
Bi and Ba are excellent alloy additives and can be added to positive grid alloys for long-life lead-acid batteries. Acknowledgements We acknowledge the assistance and guidance of Dr. Boris Monahov from the Advanced Lead Acid Battery Consortium (International Lead Association) with this project.
In some instances, the entire battery system is colloquially referred to as an “aluminum battery,” even when aluminum is not directly involved in the charge transfer process. For example, Zhang and colleagues introduced a dual-ion battery that featured an aluminum anode and a graphite cathode.
Due to the advantages of high hydrogen evolution overpotential and low water loss of lead-calcium alloy, it has been generally used in the maintenance-free lead-acid batte-ries. However, due to the high corrosion rate of lead-calcium alloy and the poor performance of deep cycling, its application is greatly inhibited [7, 8].
In recent years, lead-acid battery performance has been greatly improved with the development of the lead carbon technolo-gy, especially the service life [1–3]. As well demonstrated, the performance of the grid alloy, mainly the lead-antimony alloy and lead-calcium alloy [4, 5], plays an important role in the service life of lead-acid batteries.
Significantly, Bi and Ba will reduce the oxygen evolution overpotential of the alloy by about 30 mV, which will play important roles on the maintenance-free performance of lead-acid batteries. Both Sr and Ge promote the grain corrosion and intergranular corrosion of the alloy, reducing the corrosion resistance of the alloy.
