What is a wet cell battery?
Battery is a device that creates electricity using chemical reactions. There are two types of batteries: wet cells and dry cells. Wet cell battery operates using a liquid electrolyte solution, while in the battery of a dry cell is a solution in the form of a paste. Some wet cells can be recharged, while others are only good for a shorter time. In the end, however, all such batteries become unusable and must be replaced.
different types
There are a number of different types of wet cell batteries categorized as "primary" or "secondary". Primary batteries can only be used until its chemicals are exhausted and can no longer react together. Unlike this, the secondary battery can be recharged by efficient perversion of the inner chemical process used to generate charge.
Composition of some batteries
Most cars use wet cells. The main acid battery that often occurs in such vehicles is the secondary Batters that contains OLOVO, lead oxide, plates and solution of liquid electrolyte containing 65% water and 35% sulfuric acid. Some of the boards are anodes connected to a negative terminal, while others are cathodes attached to a positive terminal.
How does it work
When the terminals of wet cells are connected to the terminals of the wet cells, there is a chemical reaction between lead, lead oxide and electrolyte solution. As a result of the reaction, the electricity of the terminal flows to the load and sulfuric acid is removed from the solution and tied to the boards. When the battery is charged by passing the inverted current through it, the bonds between the plates and the sulfuric acid are broken and the sulfuric acid returns to the liquid solution, allowing it to provide more electricity.
Long -term use and exchange
After prolonged use, no longer wet cells can be sufficient to load enough electricity. This happens because during the course of noThe ASU is inserted on the positive boards during normal expansion and contraction of discharge and charging cycles. When the material is inserted, the boards are reduced and the flakes form the sediment at the bottom of the battery, which eventually kill the inserts and the battery completely.
Wet cell batteries often die faster in hot climates, as the heat causes the plates either accumulate or lose the material, and also because the water evaporates from the electrolyte solution. In addition, long -term use of battery, excessive vibration and overcharging can cause the battery to die faster. Once this point is reached, it cannot be charged and needs to be replaced.
History of wet cells
batteries have been used for more than a century, and archaeological evidence shows that galvanic cells can be used 2,000 years ago. The mybatery of T cells was one of the first modern types of batteries. John Frederic Daniell created the first battery of wet cells in 1836, which was better than previous versions because BYla safer and more reliable, although it could not be moved and was quite fragile. Since then, many improvements have created these batteries that are commonly used today.
