Lead Acid Battery – The type of battery which uses lead peroxide and sponge lead for the conversion of the chemical energy into electrical energy, such type of the electric battery is called a lead acid battery. Because it has higher cell voltage and lower cost, the lead acid battery is most often used in power stations and substations.
We know, a lead acid storage battery is made by connecting multiple lead acid cells in series or parallel. The capacity of the lead acid storage battery depends on the number of the lead acid cells used. Any custom size lead acid battery can be made if you know about the connections. There are basically two parts of the lead-acid battery.
Pure lead is too soft to use as a grid material so in general the lead is hardened by the addition of 4 – 6% antimony. However, during the operation of the battery the antinomy dissolves and migrates to the anode where it alters the cell voltage. This means that the water consumption in the cell increases and frequent maintenance is necessary.
The construction of a lead acid battery cell is as shown in Fig. 1. It consists of the following parts : Anode or positive terminal (or plate). Cathode or negative terminal (or plate). Electrolyte. Separators. Anode or positive terminal (or plate): The positive plates are also called as anode. The material used for it is lead peroxide (PbO 2).
The method of regenerating active material is called charging. The sealed lead-acid battery consists of six cells mounted side by side in a single case. The cells are coupled together, and each 2.0V cell adds up to the overall 12.0V capacity of the battery.
The Lead acid storage cell +ve plate is made of lead peroxide (PbO2) and the negative plate is made of Sponge Lead i.e Pb. Light Sulfuric acid is used as the electrolyte.

The absorbed glass mat (AGM) in the sealed lead acid version uses a glass fiber mat as a separator that is soaked in sulfuric acid. The earlier gelled lead acid developed in the 1970s converts the liquid electrolyte into a semi-stiff paste by mixing the sulfuric acid with a silica-gelling agent. Gel and AGM batteries have slight differences in ...
A 12-volt motorcycle battery is made up of a plastic case containing six cells. Each cell is made up of a set of positive and negative plates immersed in a dilute sulfuric acid solution known as electrolyte, and each cell has a voltage of around 2.1 volts when fully charged. The six cells are connected together to produce a fully charged battery of about 12.6 volts. …
Lead-Acid Battery Cells and Discharging. A lead-acid battery cell consists of a positive electrode made of lead dioxide (PbO 2) and a negative electrode made of porous metallic lead (Pb), both of which are immersed in a …
Sealed lead acid batteries are integral components of medical devices, including portable ultrasound machines, defibrillators, patient monitoring equipment, and medical carts. These batteries provide reliable power for critical medical procedures and patient care, contributing to the efficiency of healthcare facilities. 5. Renewable Energy Storage. Off-grid …
The six cells are connected together to produce a fully charged battery of about 12.6 volts. That''s great, but how does sticking lead plates into sulfuric acid produce electricity? A battery uses an electrochemical reaction to convert chemical energy into electrical energy.
Figure 4: Comparison of lead acid and Li-ion as starter battery. Lead acid maintains a strong lead in starter battery. Credit goes to good cold temperature performance, low cost, good safety record and ease of recycling. [1] Lead is …
Grids can also be formed by mechanical working, either by cutting deep grooves into a sheet of steel, or by rolling up crimped strips and inserting them into holes in a cast plate, see Metal Forming TLP. The lead can be oxidised by two processes: The Barton pot and the ball mill.
Lead acid batteries are heavy and contain a caustic liquid electrolyte, H 2 SO 4 (aq), but are often still the battery of choice because of their high current density. Since these batteries contain a …
