Most people know the lead acid battery simply as a car battery. The lead acid battery is the most widely used type of storage cell. They are relatively cheap, provide high current, and have a long lifetime. Each year over 100 million are manufactured around the world and there are well over five million currently in use across Australia1.
The lead acid battery, with its ability to deliver high current for a short time and its ease of recharging between uses, is well suited for starting the engines of cars. Car batteries are exclusively the lead acid type. As a standing power source, eg for telecommunications, the lead acid battery still reigns supreme.
A primary cell, such as the dry cell or alkaline cell cannot be recharged. This is because the products of the discharge reaction slowly migrate away from the electrodes and are consumed by side reactions occurring in the cell. Hence, when the cells are flat they must be discarded and new ones purchased. The lead acid battery is a secondary cell.
The lead acid battery is the most widely used type of storage cell. It is an electrochemical cell which converts chemical energy into electrical energy. During discharge of the cell a spontaneous redox reaction occurs in which electrons flow from the negative anode through the external circuit to the positive cathode.
A lead-acid battery is made up of a number of lead-acid galvanic (voltaic) cells connected up in series. When a lead-acid cell is producing electricity (discharging) it is converting chemical energy into electrical energy. Discharging a lead-acid battery is a spontaneous redox reaction.
When a single lead-acid galvanic cell is discharging, it produces about 2 volts. 6 lead-acid galvanic cells in series produce 12 volts. The battery in a petrol or diesel car is a 12 volt lead-acid battery. Lead-acid cells are rechargeable because the reaction products do not leave the electrodes.
