What is a battery plate?
Battery Plates: The battery plates consist of lead dioxide (positive plate) and sponge lead (negative plate). These plates participate in chemical reactions, storing energy as chemical potential. During charging, lead sulfate formed during discharge converts back to lead oxide and sponge lead.
What happens if a battery reaches a negative plate?
When the excess current is passed in the battery, it will cause the water to undergo electrolysis. This is a process through which, water is decomposed into its constituent gases of hydrogen and oxygen. Hydrogen gas moves to the negative plate where it is then liberated into the atmosphere.
What is the difference between a negative and a positive battery?
The negative set of plates will be composed of pure lead in a spongy form, while the positive will consist of peroxide of lead. The foregoing description gives the final products of the chemical changes that take place in the storage battery. To understand the changes themselves requires a more detailed investigation.
What is the difference between a positive and negative lead plate?
The positive plate has its effective surface area increased ten-fold by forming close-pitched fins on the surface of a pure lead plate. The negative plate was commonly of a ‘box’ form. The active material applied to open-mesh grids cast in antimonial lead is a paste made by mixing lead oxide with water and sulphuric acid.
What is the positive active material of a lead–acid battery?
In the charged state, the positive active-material of the lead–acid battery is highly porous lead dioxide (PbO 2). During discharge, this material is partly reduced to lead sulfate. In the early days of lead–acid battery manufacture, an electrochemical process was used to form the positive active-material from cast plates of pure lead.
What is a positive electrode in a lead-acid battery?
In the early days of lead–acid battery manufacture, an electrochemical process was used to form the positive active-material from cast plates of pure lead.
