how lithium-ion batteries work

Inside lithium.
Lithium ion battery pack and battery-
The ion battery pack has a variety of shapes and sizes, but their interior looks the same.
If you want to take apart the laptop battery pack (
Something we don\'t recommend because it\'s possible to short-circuit the battery and cause a fire)
You will find the following: if the battery pack gets too hot during charging or use, the computer will turn off the power flow and try to cool things.
If you put your laptop in a very hot car and try to use it, this computer may prevent you from powering up before things cool down.
If the battery is fully discharged, the battery pack is turned off because the battery is damaged.
It can also track the number of charge/discharge cycles and send messages so that the battery meter of the laptop can tell you how much power is left on the battery.
This is a very complex computer that draws energy from the battery.
This power consumption is one of the reasons for lithium.
Ion batteries lose 5% of their power every month when they are idle.
Like most batteries, you have a metal case.
The use of metal is particularly important here because the battery is pressurized.
This metal case has pressure-
Sensitive vents
If the battery is too hot, it is possible to explode because of overheating.
Pressure, this vent will release additional pressure.
The battery may be useless after that, so it needs to be avoided.
As a safety measure, air vents are strictly present.
The positive temperature coefficient is also (PTC)
Switch, a device that prevents the battery from overheating.
This metal housing has a long spiral that includes three flakes pressed together: inside the housing, these flakes are submerged in organic solvents that act as an electrolyte.
Ether is a common solvent.
The separator is a very thin micro-perforated plastic.
As the name implies, it separates positive and negative electrodes while allowing ions to pass through.
The positive electrode is made of lithium cobalt oxide or licoo2.
The negative pole is made of carbon.
When the battery is charged, the lithium ion moves from the positive to the negative and is attached to carbon.
During the discharge, the lithium ion moves back from carbon to LiCoO2.
The movement of these lithium ions occurs at a fairly high voltage, so 3 is generated per battery. 7 volts.
This is much higher than 1.
5 V typical ordinary AA alkaline batteries you buy in the supermarket, help to make lithium-
In small devices such as mobile phones, ion batteries are more compact.
For more information on the chemical composition of different batteries, see how the batteries work.
Let\'s see how to extend the life of lithium.
