General advantages and disadvantages of lead-acid batteries. Lead-acid batteries are known for their long service life. For example, a lead-acid battery used as a storage battery can last between 5 and 15 years, depending on its quality and usage. They are usually inexpensive to purchase. At the same time, they are extremely durable, reliable
The lead sulfate first forms in a finely divided, amorphous state and easily reverts to lead, lead dioxide, and sulfuric acid when the battery recharges. As batteries cycle through numerous discharges and charges, some lead sulfate does not recombine into electrolyte and slowly converts into a stable crystalline form that no longer dissolves on

As shown in reaction formula for the discharging of battery, at the negative electrode, metallic lead reacts with the sulfate ions in water solution to produce lead sulfate and release electrons (Formula 1). At the positive electrode, lead dioxide reacts also with the sulfate ions in solution to produce lead sulfate and water (Formula 2).

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.
Future performance goals include enhanced material utilization through more effective access of the active materials, achieving faster recharging rates to further extend both the cycle life and cal-endar life and to reduce their overall life cycle cost with a direct impact on the implementa-tion of grid storage systems.
A typical lead–acid battery contains a mixture with varying concentrations of water and acid. Sulfuric acid has a higher density than water, which causes the acid formed at the plates during charging to flow downward and collect at the bottom of the battery.
The reaction principle of lead-acid battery remains unchanged for over 150 years from the invention. As shown in reaction formula for the discharging of battery, at the negative electrode, metallic lead reacts with the sulfate ions in water solution to produce lead sulfate and release electrons (Formula 1).
According to a 2003 report entitled "Getting the Lead Out", by Environmental Defense and the Ecology Center of Ann Arbor, Michigan, the batteries of vehicles on the road contained an estimated 2,600,000 metric tons (2,600,000 long tons; 2,900,000 short tons) of lead. Some lead compounds are extremely toxic.
Furthermore, lead-acid batteries are made of very simple materials such as lead (alloy), resin, glass, water, and sulfuric acid. And because melting point of the lead is 327.46 °C which is lower than other metals, the used lead-acid batteries can easily be recycled to retrieve lead material.
Specific energy density of lead acid-batteries is 30–40 Wh/kg, which is only about one-third of Lithium ion batteries. Therefore the lead-acid batteries are not used for personal computer, mobile phone, and electric vehicle at present in most cases, and also considered not to be used for such mobile devices for the future.
In the early days of lead acid batteries, the corrosion layers formed on the surface of lead sheet were used as active materials. But at present, the pasted type electrodes, which are made from lead-oxide paste and lead-alloy grid, are used generally.
