What is a lead acid battery?

A lead acid battery consists of electrodes of lead oxide and lead are immersed in a solution of weak sulfuric acid. Potential problems encountered in lead acid batteries include: Gassing: Evolution of hydrogen and oxygen gas. Gassing of the battery leads to safety problems and to water loss from the electrolyte.

How many Watts Does a lead-acid battery use?

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.

What are the problems encountered in lead acid batteries?

Potential problems encountered in lead acid batteries include: Gassing: Evolution of hydrogen and oxygen gas. Gassing of the battery leads to safety problems and to water loss from the electrolyte. The water loss increases the maintenance requirements of the battery since the water must periodically be checked and replaced.

What happens when a lead acid battery is charged?

5.2.1 Voltage of lead acid battery upon charging. The charging reaction converts the lead sulfate at the negative electrode to lead. At the positive terminal the reaction converts the lead to lead oxide. As a by-product of this reaction, hydrogen is evolved.

What is the charge/discharge reaction in lead-acid batteries?

The basic overall charge/discharge reaction in lead–acid batteries is represented by: Besides the chemical conversion of lead dioxide and metallic lead to lead-sulfate, also sulfuric acid as the electrolyte is involved in the cell internal reaction.

How much lead is in a car battery?
