Have you ever thought that how your watch goes on round the clock for years? These are not silly questions to think. These questions can help us to provide the answer to how a battery works. The battery in the watch, calculator or all other small appliances needs a greater amount of energy to run. Button size batteries or coin size batteries have fantastic energy generation. These small appliances need a very gigantic amount of energy and one cannot change the batteries in a regular and frequent time. They need to be stable and long-lasting, therefore, lithium is used as the basic constituent’ element of the battery. Unlike the other batteries, the alkaline or lead acid battery has a very smaller age or they generate very less amount of energy. Therefore, lithium is used in these batteries because they can sustain a better life. Coin cell lithium batteries have great advantages in the industry of small batteries.
Structure and Chemistry
Coin cell lithium is very simple in diagram. These batteries have a metallic body with two slices of metals, one at the upper end and other at the lower end. The lower end metal is the complete body of the battery and is charged negatively and the upper end is positive. Both these terminal are separated with a rubber or a plastic lining, so that they do not fuse together. The body of the battery contains the chemical which makes the power to generate the current. These chemical contain lithium as the base. Many other elements such as manganese oxide, carbon mono fluoride or many others make variations in the power of the battery. These chemical are considered to have no such element that is dangerous for anyone’s health. Mercury is also used but in some general appliances of industry with specification of disposure. These batteries are packed in such manner that they may not leak or spoil, if they are not use for a long time of period. Usually, in the bigger batteries, we face the problem of leakage of chemical acid but these batteries are much secured and packed.
Coin cell lithium battery has a very good energy generating capability. They usually provide 3 volts but some are made to provide 1.5 volts too. They are long-lasting for a quiet good age. They almost give 5000 mAh of energy.
Coin cell lithium batteries are used everywhere in the watch, cell phones and all the other small devices. The small devices cannot place a big battery in them therefore, these battery are made in such a manner that they can be placed in these appliances and give less energy. These batteries are used in the remotes more often. Small remotes of car-lock and player require these kinds of batteries. These batteries are also used in watches give a life age of at least 3 years. Moreover, these batteries are used in the pacemaker planted in the chest after a heart surgery to provide additional power to the heart to beat.
Coin cell lithium is used in almost every appliances for a backup support.
