The equation should read downward for discharge and upward for recharge. The battery which uses sponge lead and lead peroxide for the conversion of the chemical energy into electrical power, such type of battery is called a lead acid battery. The container, plate, active material, separator, etc. are the main part of the lead acid battery.
The ease with which the lead–acid battery is recycled has made the lead–acid battery the captive user of most secondary lead. Moreover, technologies have been developed in the last few decades that enable recycling of other components of a lead–acid battery such as acid and plastic and these will further ease environmental concerns.
The purpose of this article is to describe the conventional effluent purification processes used for the recovery of materials that make up lead acid batteries, and their comparison with the advanced processes already being implemented by some environmental managers.
The lead acid battery is most commonly used in the power stations and substations because it has higher cell voltage and lower cost. The various parts of the lead acid battery are shown below. The container and the plates are the main part of the lead acid battery.
Lead from recycled lead–acid batteries has become the primary source of lead worldwide. Battery manufacturing accounts for greater than 85% of lead consumption in the world and recycling rate of lead–acid batteries in the USA is about 99%. Therefore, battery manufacturing and recycled lead form a closed loop.
It is evident that the segregation and independent treatment of the most polluting effluents from dismantling and washing lead-acid batteries means that much of the rest of the effluents can be discharged; this therefore simplifies their treatment and minimises the environmental impact.

In this paper, a novel method for regenerating lead paste, by vacuum reduction reaction coupling with separation of Pb-Sb alloy, was developed. In this process, antimony from Pb-Sb alloy is used to reduce desulfurized lead paste into lead under vacuum, while it is oxidized into volatile Sb 2 O 3 as by-product.
Returning used lead batteries to the recycling loop has a long tradition. Thanks to the compactness of a battery, its high lead proportion (>95%) and relatively high metal prices, it has been worth while for consumers to return their own or collected car batteries to the scrap trade or secondary smelters. The return rate of
The only legally acceptable method of disposing lead-acid batteries is to recycle them at a Resource Conservation and Recovery Act [RCRA] approved secondary smelter managed under the Environmental Protection Agency [EPA].
main content: 1. Disassembly of the battery 2. Battery preconditioning 3. Environmental issues during battery disassembly and pretreatment Regardless of the technology used, the acidic electrolyte produces complex chemical reactions when the lead is melted. Therefore, the acid of waste lead-acid batteries must be drain
The lead–acid battery is an old system, and its aging processes have been thoroughly investigated. Reviews regarding aging mechanisms, and expected service life, are found in the monographs by Bode [1] and Berndt [2], and elsewhere [3], [4]. The present paper is an up-date, summarizing the present understanding. New aspects are: interpretation of …

In flooded lead–acid batteries, roughly 85% of all failures are related to grid corrosion, while in valve-regulated lead–acid batteries, grid corrosion is the cause of failure in about 60% of cases. This is a problem that develops over time and it typically affects batteries that are close to end of life. In other words, if the preventable causes of failure are eliminated, then …

Working Principle of Lead Acid Battery. When the sulfuric acid dissolves, its molecules break up into positive hydrogen ions (2H +) and sulphate negative ions (SO 4 —) and move freely. If the two electrodes are immersed in solutions and connected to DC supply then the hydrogen ions being positively charged and moved towards the electrodes and ...
In principle, lead–acid rechargeable batteries are relatively simple energy stor-age devices based on the lead electrodes that operate in aqueous electro- lytes with sulfuric acid, while the details of the charging and discharging processes are complex and pose a number of challenges to efforts to improve their performance.

Secondary lead, i.e. material produced by the recycling of lead-acid batteries has become the primary source of lead in much of the world. This has been important to the secondary lead industry as other uses have dwindled, e.g. lead based pigments, chemicals, fuel additives, solders and CRT glasses [1].Presently, battery manufacturing accounts for greater …
is used for charging some small lead-acid batteries, the constant current charging method is not widely used for lead-acid batteries, because of the gassing which is likely to occur when charging a battery too long. The risk of gassing is more important when charging a battery which is only partially discharged.
