Corrosion on Negative Battery Terminal- Introduction,Cause and Solution

As humanity progresses, we notice many changes in technology and advancement. This technological advancement is something that cannot be avoided and the reason for that is convenience. the modern era has human beings that ask for convenience above all. these are the type of people who do not want to wait for the results of their hard work but they want quick results so that they can progress ahead or move on. In the past people used to have calculators of the size of an entire building however now that is something that can be done on a mere watch that is worn over your wrist. There are many other such inventions and advancements that if continued to mention the list would not end for example the invention of electricity is also considered one of the biggest ones due to the fact that it is now being used in almost every household that we know even in the areas where there are no electrical production sites there are electrical appliances.

One such invention is that of the battery, this is also a great invention and the reason for that is quite simple. It is a major source for electrical appliances power without which any electrical appliances will not run. A battery is a relatively simple device which involves three main types of components, it consists of an anode, and cathode and last but not the least an electrolyte. Taking an example of the lithium-ion battery or the Li-On Battery we will be explaining how a battery works and what principle the battery uses to perform what it does a battery consist of cathode which functions to produce electrons that are discharged into the electrolyte solution, anode functions as a positive terminal for the electrons and therefore receives the electrons that are being shot out from the cathode. An electrolyte solution in an electrolyte solution in a battery such as that of the lithium oxide one in consist of a lithium metal oxide that is being dissolved into an organic solvent such as phenol solution or something else. So, these are the essential components that are needed to make sure that any battery works or performs in the most optimum manner that is available. There are go several types of redox reactions there then produce energy that is needed for working of any appliance that is available or attached to that battery. 

Blue Corrosion

The blue corrosion that you will see on any battery is due to the copper sulphate corrosion that produces a sort of insulation around the terminal of your battery which would have been used for the purposes of producing electricity and transmitting it to the battery cables and therefore providing energy to the appliances that are fitted within the car. This type of corrosion can vary in colors for example it can be of white green or blue color. This type of battery corrosion is basically due to the accumulation of hydrogen gas that is being produced as a result of reaction that is taking place within the electrolyte medium of sulfuric acid within the battery. as these gases are released from the battery they react with the surrounding atmosphere as a result of which it begins to produce a certain corrosive element which is a typical type of oxide between the battery cable that is touching or connected to the terminal and the terminals of the battery. As soon as this process of corrosion starts the other outside factors such as moisture as well as other types of salts that are present within the atmospheric air are also promoting factors for such type of corrosions, typically a battery corrosion usually happens at the negative terminal of the battery.

Causes of Corrosion 

Corrosion can be due to many causes, the major one is that the battery has its own impurities that can lead up to the many problems, for example they can cause many reactions that may not be needed with in the battery and this can result in the production of several gases that will eventually float up to the top and therefore cause them to escape as a result of which the major thing that will happen is that they will react with the surrounding environment. Now the surrounding environment itself has many impurities that when you start to think about have a great chance to combine with the afloat toxic and reactive gases therefore producing corrosion. The atmosphere also has a bunch of moisture as well this only promotes the corrosive process. All of such factors contribute to the production of corrosion, the other thing is that these gases basically penetrate the spaces between the point where the terminal is touching the battery cables, then at that point they cause the buildup of oxides, these oxides are the cause of weak electrical output which when dampens with time this causes more buildup of corrosion therefore starting a dangerous never-ending cycle of problems that would have otherwise been easy to deal with. These are the causes of corrosion; the last cause of such corrosion is the use of the water that has not been distilled properly because, this water is not purified completely it is liable to have many impurities that then produce oxides that will eat the battery as well therefore hindering in the ability of the battery charging and discharging. 

Buildup on negative terminal

The main and the primary reason as to why the battery is developing this corrosion specifically on the negative side of the battery is due to the fact that this battery side when undercharged cause the buildup of several sorts of hydrogen gases and these hydrogen gases then react with the components of the battery and therefore are the main reason as to why they produce oxides. These oxides then have the ability to basically clog the electrical supply eventually deeming the battery useless. The main reason why the negative terminal gets more corrosion is due to the fact that there are many more reactions that are taking place on that side.
