Batteries can explode through misuse or malfunction. By attempting to overcharge a rechargeable battery or charging it at an excessive rate, gases can build up in the battery and potentially cause a rupture. A short circuit can also lead to an explosion. A battery placed in a fire can also lead to an explosion as steam builds up inside the ...
Considering that the lead–acid battery dominates consumption of the element, around 80% of world lead output, it is not surprising to find that secondary lead sourced from batteries is the major contributor to the world's annual lead production of 8.4 million tons.
It consists of a spongy metallic lead anode, lead dioxide (PbO 2) cathode, and an electrolyte of a diluted mixture of aqueous sulfuric acid (H 2 SO 4) with a voltage range of 1.8–2.2 V. Lead–acid batteries are shock-resistant, reliable, durable, cheap, and capable of withstanding extreme temperatures .
Lead acid batteries typically have coloumbic efficiencies of 85% and energy efficiencies in the order of 70%. Depending on which one of the above problems is of most concern for a particular application, appropriate modifications to the basic battery configuration improve battery performance.
This comes to 167 watt-hours per kilogram of reactants, but in practice, a lead–acid cell gives only 30–40 watt-hours per kilogram of battery, due to the mass of the water and other constituent parts. In the fully-charged state, the negative plate consists of lead, and the positive plate is lead dioxide.
The usable life of a lead acid battery is typically approximately 5 years or 250–1000 charge-discharge cycles, depending on the depth of discharge . P. Kurzweil, in Reference Module in Chemistry, Molecular Sciences and Chemical Engineering, 2023 The lead-acid battery is the most important low-cost car battery.
Lead–acid batteries are the dominant market for lead. The Advanced Lead–Acid Battery Consortium (ALABC) has been working on the development and promotion of lead-based batteries for sustainable markets such as hybrid electric vehicles (HEV), start–stop automotive systems and grid-scale energy storage applications.

There are two general types of lead-acid batteries: closed and sealed designs. In closed lead-acid batteries, the electrolyte consists of water-diluted sulphuric acid. These batteries have no gas-tight seal. Due to the electrochemical potentials, water splits into hydrogen and oxygen in a closed lead-acid battery.
For a typical 12 V battery v s varies from 12.7 V fully charged to 11.7 V when the battery is almost fully discharged. Internal resistance R S is also a function of the state of charge and temperature. When the battery provides current, there is a voltage drop across R S, and the terminal voltage v < v s.

Lead-Acid Battery Construction. The lead-acid battery is the most commonly used type of storage battery and is well-known for its application in automobiles. The battery is made up of several cells, each of which consists of lead plates immersed in an electrolyte of dilute sulfuric acid. The voltage per cell is typically 2 V to 2.2 V.
Lead-acid batteries have specific battery charging area requirements that lithium-ion batteries do not. This is because lead-acid batteries have the potential for safety hazards such as acid leaks and spills, venting explosive gases, and high temperatures. Due to their risks, lead-acid forklift batteries require a separate charging area . Consequently, OSHA …
About 60% of the weight of an automotive-type lead–acid battery rated around 60 A·h is lead or internal parts made of lead; the balance is electrolyte, separators, and the case. [8] For example, there are approximately 8.7 kilograms (19 lb) of lead in a typical 14.5-kilogram (32 lb) battery.
