Lead acid batteries are made up of plates, Lead, and Lead oxide situated in a “bath” of 35% sulfuric acid within a plastic casing and 65% water electrolyte solution. Lead acid batteries represent almost 60% of all batteries sold worldwide.
This means the typical Lead-acid battery comprises of: metal grids, electrode paste, Sulphuric acid, connectors and poles of Lead alloy, and grid separators made up of PVC. The battery components are contained in corrosion and heat-resistant housing usually composed of plastic (polycarbonate, polypropylene, or polystyrene).
Generally there are two types of Lead-acid storage batteries, based on their method of construction Flooded or Sealed. Flooded (or wet) Lead acid batteries are those where the electrodes / plates are immersed in electrolyte. Sealed Lead acid or valve-regulated Lead acid (VRLA) battery where the electrolyte is immobilized. All Lead-acid batteries produce hydrogen and oxygen gas (gassing) at the electrodes during charging through a process called electrolysis. These gases are allowed to escape a flooded cell, however the sealed cell is constructed so that the gases are contained and recombined.
Lead acid batteries are used in every country in world, and can commonly be recognized as “car batteries”. The batteries can be charged many times, but after numerous cycles of recharging, lead plates eventually deteriorate causing the battery to lose its ability to hold stored energy for any period of time.Once the lead acid battery ceases to be effective, it is unusable and deemed a used lead acid battery (ULAB)
Also Lead-acid batteries are a common item in our daily lives. Once the lead of the battery is timed out, we have no option but to dump it because it has no use for us anymore, but the copper plates in the battery remain reusable which can be used for recycling. There are some disagreements about the benefits of recycling battery, say alkaline battery, over simple disposal because the mercury in the battery no longer exists and the disposal material is abundant and non-toxic. But for automotive batteries the scenario is different in terms of benefits. The recycling of this type of battery holds both economic and environmental benefits. We also receive special types of batteries like gel cell, back ups for computers, emergency lighting, telephone communications, and certain tools.
The reusable material from the used battery is removed and recycled which reduces the needs for raw materials which is originally imported from abroad. It creates a balance payment and cost. In addition to this there can be considerable environmental impact during mining processes such as emission from smelting of sulfide ore, copper, nickel, and cobalt and this can be eliminated if recycling can be introduced.
Recycled lead is a valuable commodity and for many people in the developing world. the recovery of car and similar batteries (ULABs) can be a viable and profitable business. Therefore, the market for reclaiming secondary lead has been growing, especially in developing countries. Many developing countries have entered the business of buying ULABs in bulk in order to recycle them for lead recovery. These ULABs are often shipped over long distances for recycling, typically from the industrialized countries that produce, use, and then collect the spent batteries for reprocessing.
Currently ULAB recycling occurs in almost every city in the developing world, and even in some countries in rapid transition.
About 6 million tons of lead is used annually, on a worldwide basis, of which roughly three-quarters goes into the production of lead-acid batteries, which are used in automobiles, industry and a wide range of other applications. Much of this existing demand for lead is met through the recycling of secondary material and in particular from lead recovered from Used Lead-Acid Batteries (ULAB). This high level of recycling is very effective in reducing the volumes of lead dumped in the environment and in minimizing the need for mining more ores.
