How about charging and discharging lithium batteries correctly?

The correct charging method of lithium battery is to grasp the time and prevent overcharging. Do the right thing at the right time, although the lithium battery itself has excellent electrochemical performance, however, any kind of thing will have a safety hazard after it deviates from the equilibrium state. In detail, 1. When you are full, you are full. In the early days of the emergence of smart phones, out of the original intention of protecting their own interests, each mobile phone manufacturer often emphasized the use of original chargers (including charging cables) to charge electrical equipment. Some manufacturers designed special data cables and did not support others. Charger (including charging cable). Later, as the application of smart phones and laptops became more and more widespread, it was obvious that it would be a cocoon to continue this way, so now everyone has basically unified the standard, and a charger/cable can charge electrical appliances of different brands and properties. Charging is convenient, and a problem that users should pay attention to is to try to keep the battery with the power of normal use at all times. Under normal circumstances, when the battery is too low, both the mobile phone and the laptop will give a reminder. At this time, you must recharge the battery in time. Although the low battery will not cause a direct safety accident, overuse will cause damage to the battery structure over time. . 2. Just fill it up. Lithium battery cells are also made up of many components. The new battery is fine. If it takes a long time, the function of which component may deteriorate, so there will be a risk of overcharging safety. Several typical accidents in which Samsung and Apple were exposed were caused by the owners of electrical appliances putting their mobile phones on the bedside to charge them when they were sleeping, * causing burns and explosions. 3. Do not use one mind and two purposes. I have experienced that using the mobile phone while charging it, especially when playing games, it is easy to feel the mobile phone heat up. The reason is also very simple. The mobile phone is equivalent to doing two jobs at the same time. Up. The correct discharge method of lithium battery is charged in time to prevent over-discharge. Ordinary mobile phone users are not aware of the hazards of over-discharge, because there are usually no reports of safety incidents in over-discharge. Moreover, some people even think that regular deep discharge is good for maintaining battery performance. In fact, this is not the case, because the memory effect of lithium batteries is negligible, and there is no such thing as a deep discharge to eliminate the memory effect. Theoretically speaking, the total cycle life of a lithium battery with deep discharge will be longer, but the risk is that over-discharge of the battery will cause the battery voltage to be too low and cannot be charged normally, sometimes it will take a long time to turn on, or even fail to turn on. The two evils are the lesser one. A shorter service life is better than no use. Therefore, users of mobile phones and laptops are advised not to frequently use black screens.
