What are the reasons why lithium batteries are not suitable for recharging without electricity?

There are actually many principles and types of lithium batteries. However, most lithium batteries work with an important substance that is lithium ion. So to be precise, it should be called a lithium battery. Lithium ions are stored in electrode materials (such as graphite) when they are not working. Graphene, which is relatively hot recently, is also one of the electrode materials. There are many pores in these electrode materials, and lithium ions are embedded in these pores. When the battery starts to work, the battery is discharged to the outside. Lithium ions escape from the pores and enter the electrolyte solution. At this time, the pores of the electrode material become weaker due to the lack of lithium ion support. Under external pressure, collapse easily occurs. When charging, lithium ions have to return to the pores. If the pores collapse, there will be fewer pores that can hold lithium ions, and the lithium ions will not go back, and it will not be able to be charged. There are fewer and fewer pores in the electrode material, and less and less electricity can be charged. And this will lead to a vicious circle, which will eventually result in the battery being scrapped and unusable. This is why lithium batteries cannot be over-discharged. Of course, overcharging is also bad. Especially for some people, charging while using it is even worse for the battery. Will affect the service life of the battery. It is best to charge when the power drops to 20-30%. Today's mobile phones are equipped with a fast charging function. It will quickly charge to 80-90, and then become a trickle slow charge, to guard against excessive battery damage to the battery. At this time, you can stop charging. There is no need to wait for it to overflow. Don't always plug it into the power source. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
