The correct maintenance method of lithium battery

The general principle that needs to be followed when using lithium batteries is shallow charge and shallow discharge, that is, to recharge the lithium battery in time, do not wait until the battery is almost empty and then recharge, which is bad for the life of the lithium battery; in addition, do not use lithium at high or low temperatures The battery, preferably at room temperature, the temperature will have a great influence on the characteristics of the lithium battery, so it is best to have a temperature adjustment system; the lithium battery may catch fire or even explode when punctured or severely hit.
The working principle of a lithium battery is nothing more than charging to store energy, and discharging is converted into other energy and released. It is in an idle state when it is neither charging nor discharging. Therefore, the correct use of lithium batteries has three major aspects: correct charging, correct discharging, and correct maintenance.

Correct charging method of lithium battery
1. In the early days of the emergence of smartphones, 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 them. Other chargers (including charging cables). Later, as the application of smart phones and laptops became more and more widespread, it would be obvious that it would be a cocoon to continue this way, so now everyone has basically unified the standard, 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 remind you. At this time, you need to recharge it in time. Although the low battery will not cause a direct safety accident, overuse will cause damage to the battery structure over time. . 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 safety hazards when it deviates from the equilibrium state.
2. Just fill it up. The inside of the lithium battery cell is also composed of many components. The new battery is okay. If it takes a long time, maybe the function of each component will decline, so there will be a risk of overcharging safety. Several typical accidents in which Samsung and Apple were exposed were due to the owners of electrical appliances.People put their mobile phones on the head of the bed to charge them when they sleep, which will eventually cause burning and explosion.
3. Do not use one mind and two purposes. The author has experienced that using the phone while charging, especially when playing games, it is very easy to feel the phone heat, the reason is also very simple, The mobile phone is equivalent to doing two jobs at the same time, which makes you have to pay more than double the labor force, the body will naturally get fever.

Correct discharge method of lithium battery
Charge 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. and,Some people even think that regular deep discharge is good for the maintenance of battery performance. In fact, this is not the case, because the memory effect of lithium batteries is negligible and does not exist.
The argument that the deep discharge eliminates the memory effect. Theoretically, the total cycle life of a lithium battery with deep discharge is greater, but the risk is that the battery is over-discharged.It will cause the battery voltage to be too low and it will not be able to charge normally, and sometimes it will take a long time to turn on, or even fail to turn on. Two evils, whichever is the least, has a shorter service life.
Pointing is better than not being able to use it, so users of mobile phones and laptops are advised not to frequently use black screens.

Lithium battery is properly maintained. The temperature is suitable, and it is cold and hot. When idle, lithium batteries usually do not have safety accidents. The purpose of daily maintenance is to keep the lithium batteries in a suitable environment.Thereby delaying the aging of the battery. In fact, one of the parameter designs of lithium batteries is the appropriate temperature. Relatively speaking, lower temperature is not a big problem, but if Putting it at a higher temperature, as the saying goes, things will be reversed, and it will also cause safety problems. The idle state we are talking about is only in terms of the normal environment, if you put Putting the lithium battery in water or close to the fire source is no longer the topic of "maintenance". So, what is to be done in a normal environment? Water aspect protects against moisture and heat.The aspect is anti-exposure. Therefore, the suitable environment for daily maintenance of lithium batteries should be four words: ventilation and coolness. Regardless of whether the lithium battery is independently idle or is using an electric appliance.
These four words should be followed in the standby mode.
