The lithium battery is a kind of energy storage conversion device. Because of its excellent electrochemical performance, it realizes a different market application scenario. When we talk about lithium batteries, it usually refers to small applications, namely consumer electronics.
Its working principle is charging to store energy. And discharging is converted into other energy and release. It is in an idle state when it is neither charging nor discharging. Therefore, the correct lithium batteries includes major aspects: correct charging, correct discharging, and correct maintenance.
Correct charging method of lithium battery
Grasp the time and prevent overcharging. Do the right thing at the right time. Although the lithium battery has excellent electrochemical performance, however, any thing will have safety hazards when it deviates from the equilibrium state.
1. Charge it when needed.
As the application of smartphones and laptops becomes widespread, it will be a cocoon if continues. So everyone has basically unified the standard, a charger/cable can charge electrical appliances of different brands and properties. Charging is convenient, and a problem is to keep the battery with the power of normal use at all times. Under normal circumstances, when the voltage is too small, both the mobile phone and the laptop will give a reminder. At this time, you need to recharge the battery in time. Although the low power will not cause a direct safety accident. But overuse will cause damage to the battery structure.
2. Stop it when full-charged.
The lithium battery cell is also composed of many components. The new battery is good. If it takes a long time, the component function may deteriorate, so overcharge safety risks will occur. Several typical accidents in which Samsung and Apple were exposed were caused by the owners, putting their mobile phones on the bedside to charge them while they slept, which eventually caused burns and explosions.
3. Don’t do two things.
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, which makes it necessary to pay over the labor force, and the body naturally heats up.
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 accidents in over-discharge. Moreover, some people think that regular deep discharge is good for the maintenance of battery performance. In fact, because the memory effect of lithium batteries is negligible, and there is no saying that deep discharge eliminates the memory effect. Theoretically, the total cycle life 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 ones. Shorter service life is better than no use. Therefore, users of mobile phones and laptops are advised not to frequently use black screens.
Proper maintenance of lithium batteries
The temperature is suitable, and it can prevent heat and cold. When idle, lithium batteries usually do not have safety accidents. The purpose of daily maintenance is to place the lithium batteries in a suitable environment to delay the age. In fact, one of the parameter designs of lithium batteries is the appropriate temperature. Relatively speaking, lower temperatures are not a big problem, but if they are placed at higher temperatures, which will also cause safety problems. The best state is only in terms of the normal environment. If the lithium battery is placed in water or close to the fire source, it will be out of the topic of “maintenance”. Then, what is to be done in a normal environment? The water side is moisture-proof and the hot side is sun-proof. Therefore, the suitable environment for daily maintenance of lithium batteries should be four words: ventilation and coolness. These four words should be followed regardless of whether the lithium battery is left unused independently or used in electrical appliances.
In the correct use of lithium batteries, the charging method of lithium batteries is the most important. Because incorrect charging methods will cause safety problems, and discharge and daily maintenance affect only the service life of lithium batteries. Lithium batteries themselves are also a kind of Consumables, no matter what we take, we can’t avoid its final loss. But we use the correct method to delay its aging.
