Lead acid batteries either start or power cars, trucks, buses, boats, trains, rapid mass-transit systems, recreational vehicles and electric wheelchairs all over the globe. Saves Natural Resources : By making products from recycled materials instead of virgin materials, we conserve land and reduce the need to mine for more minerals. Saves Clean Air and Water : In most cases, making products from recycled materials creates less air pollution and water pollution than making products from virgin materials. Saves Landfill Space : When the materials that you recycle go into new products, instead of landfills or incinerators, landfill space is conserved. Saves Money and Creates Jobs : The recycling industry and the associated processes create far more jobs than landfill sites or waste incinerators, and recycling is frequently the least expensive waste management option for cities and towns. All the components of the modern lead acid battery are recyclable and from an Industry perspective lead-acid batteries are an environmental success story because in the United States just over 96% is recovered and in most of the G7 nations upwards of 95% is recycled. Lead acid batteries, in whatever form, are all recyclable to a lesser or greater extent.
In order to ensure that the loop is closed we not only need the right infrastructure, but we also need a battery that is made up of recyclable materials. A resilient plastic container which is usually polyethylene, but increasingly is made from alternative co-polymers or reinforced, but the case material can also be metallic or a synthetic rubber. Porous synthetic plate separators are increasingly made from rib-reinforced polyethylene, but are also available in PVC and fiber glass. The plates are immersed in a liquid electrolyte consisting of 35% sulfuric acid and 65% water. The positive and negative lead terminals used to connect the battery to the car and pass the current from the individual cells via a series of connecting lugs and bridges. The washed and dried polypropylene pieces are sent to a plastic recycler, where the chips are melted and extruded to produce plastic pellets for use in the manufacture of battery cases.
Although certain processes will combine the waste lead streams, the most efficient plants feed the paste to the smelting furnace to recover soft lead and the grids and terminals are sent to a melting furnace for the production of hard lead. Polyethylene separators can be separated from the polypropylene waste stream and recycled, although in most secondary plants the current practice is to use this waste as a fuel supplement. Used battery acid can be handled in four ways: Neutralized, and the resulting effluent treated to meet clean water standards and then released into the public sewer system. Chemically treated and converted to either agricultural fertilizer using ammonia or to powered sodium sulfate for use in either glass and textile manufacturing or as a filler or stabilizer in household laundry detergent.


Converted to gypsum for use in the production of cement or by the construction industry in the manufacture of fiber board. UStudy aims to provide Educational Content for Polytechnic College students based on the latest K Scheme syllabus of Tamil Nadu.
A lead-acid battery is a electrical storage device that uses a reversible chemical reaction to store energy. A lead-acid battery is composed of a series of plates immerse in a solution of sulfuric acid. When the battery is discharged (when it is subjected to an electrical load), acid from the elecrolyte combines with the active plate material. When a battery is recharged, the opposite occurs: the lead sulfate reverts back to active material, and the electrolyte becomes more acidic with a higher specific gravity.
During discharge, the lead dioxide (positive plate) and lead (negative plate) react with the electrolyte of sulfuric acid to create lead sulfate, water and energy.
Many new competitive cell chemistries are being developed to meet the requirements of the auto industry for EV and HEV applications. Even after 140 years since its invention, improvements are still being made to the lead acid battery and despite its shortcomings and the competition from newer cell chemistries the lead acid battery still retains the lion's share of the high power battery market.

Lead acid batteries are made up of plates of lead and separate plates of lead dioxide, which are submerged into an electrolyte solution of about 35% sulphuric acid and 65% water. As the battery discharges, the acid of the electrolyte reacts with the materials of the plates charging their surface to lead sulphate.
Unless we recycle the Lead acid spent batteries certain toxic components pose a potential risk to the environment and human health. In fact secondary lead bullion, for example, requires four times less energy to make than primary lead. The positive electrode (cathode) typically consists of pure lead dioxide supported on a metallic grid, whereas the negative electrode (anode) consists of a grid of metallic lead alloy containing various elemental additives that includes one or more of the following and sometimes others not mentioned, antimony, calcium, arsenic, copper, tin, strontium, aluminum, selenium and more recently bismuth and silver. It is the electrolyte that facilitates the chemical reactions that enable the storage and discharge of electrical energy and permit the passage of electrons that provide the current flow.


It uses a combination of lead plates or grids and an electrolyte consisting of a diluted sulphuric acid to convert electrical energy into potential chemical energy and back again. Each plate consists of a grid upon which is attached the active material (lead dioxide on the negative plates, pure lead on the positive plates.) All of the negative plates are connected together, as are all of the positive plates. This causes a chemical reaction that releases electrons allowing them to flow through conductors to produce electricity. When the battery is recharged, the chemical reaction is reversed and the lead sulphate reforms into lead oxide and lead. In these situations the telephones stay on and this is because every major telephone company in the world, including mobile telephone service providers, uses lead acid batteries as backup power to the telecommunications systems.Were it not for standby lead acid batteries, we probably would have power outages nearly every day because the electric utilities would not be able to handle rapid fluctuations in the demand for electricity.
In fact, used lead-acid batteries have topped the list of the most highly recycled consumer products for over a decade.Unfortunately, battery recycling is not a public utility and scrap batteries are only recycled because it is profitable for the secondary non-ferrous industry to do so. The battery itself does nothing to close the recycling loop if it is not recycled, but you, your governments and your industries can ensure that they enter the loop by creating an infrastructure that will promote and facilitate recycling.
These alloying elements are used to change grid strength, corrosion resistance, reduce over-potential or maintenance, and internal resistance. The electrolyte of lead-acid batteries is hazardous to your health and may produce burns and other permanent damage if you come into contact with it. The electrolyte become less acidic in the process, and the specific gravity of the solution drops. This is when lead acid batteries come to the rescue, as enormous arrays of batteries delivering large amounts of electricity for short periods of time until additional capacity is added to the grid.Lead acid batteries power electric fork trucks used in warehouses, factories, mines, and ships.
The soft lead is suitable for battery paste and the hard lead bullion ideal for grids and terminals.
They also power the shuttle vehicles in airports, as well as wheelchairs, amusement park shuttles and golf carts.
On the road, lead acid batteries power electric law-enforcement vehicles, buses, and very soon mail delivery vans.
