Lithium batteries are a kind of energy storage conversion device which is more and more widely used, because their excellent electrochemical performance realizes such a market application scenario as small-medium-large, which keeps pace with the times. When we talk about the correct use of lithium batteries, we usually refer to small applications, i.e. consumer electronics, such as smartphones. A laptop computer. Because large and medium-sized applications are based on small application technology, small applications have common characteristics, and large and medium-sized applications are much more complex. Usually, medium-sized applications are on new energy vehicles, generally we call them power batteries; large applications are usually on base stations, generally we call them energy storage batteries. So when we talk about "the use of lithium batteries", it is in line with people's habit to limit lithium batteries to small applications.
The working principle of lithium batteries is nothing more than charging to store energy, discharging into other energy and releasing. The lithium batteries are idle when they are neither charged nor discharged. Therefore, the correct use of lithium batteries has three major aspects: correct charging, correct discharging and correct maintenance.
Correct charging method for lithium batteries
Grasp the time and prevent overcharging. The right time to do the right thing, although the lithium battery itself has excellent electrochemical performance, however, any kind of thing will have security risks after deviating from the equilibrium state. In detail,
1. Act as if it were. In the early days of smartphones, for the purpose of protecting their own interests, every mobile phone manufacturer often emphasized the use of original chargers (including charging lines) to charge electrical equipment. Some manufacturers designed special data lines, and did not support other chargers (including charging lines). Later, as smartphones and laptops became more and more widely used, it was obvious that they were self-restrained, so now we have basically unified standards, a charger/wire can charge different brands and properties of electrical appliances. Charging is convenient. One of the problems that users should pay attention to is to keep the battery with normal power at any time. Normally, when the power is too low, mobile phones and laptops will be alerted. At this time, you need to make up the power in time. Although the low power will not lead to a direct safety accident, overuse will cause damage to the battery structure over time.
2. Fill it up. The interior of lithium batteries is also composed of many components. The new batteries are good. If it takes a long time, the function of any component will decline, so there will be overcharge safety risk. Samsung and Apple were exposed to typical accidents, several of which were due to the electrical owner put his mobile phone on the bed while sleeping to charge, and eventually triggered a combustion and explosion.
3. Don't use both of your heart and soul. The author has experienced that it is easy to feel hot when using mobile phone while charging, especially when playing games. The reason is simple. Mobile phone is equal to two jobs at the same time, which makes it have to pay more than twice the labor force, and the body will naturally get hot.
Correct Discharge Method for Lithium Batteries
Charge in time to prevent over-discharge. Ordinary mobile phone users are not aware of the dangers of overexposure, because there are no safety incidents reported. Moreover, some people even think that periodic deep discharge is good for the maintenance of battery performance. In fact, it is not, because the memory effect of lithium batteries can be neglected, there is no theory that deep discharge can eliminate the memory effect. In theory, the total cycle life of lithium batteries with deep discharge will be longer, but the risk is that excessive discharge of lithium batteries will lead to too low battery voltage, unable to charge properly, and sometimes it will take a long time to turn on, or even not turn on. It is better to use the black screen than to use it for a short time. Therefore, it is advisable that users of mobile phones and laptops should not use black screen frequently.
Correct Maintenance of Lithium Batteries
Temperature appropriate, cold and hot proof. When idle, lithium batteries usually do not cause safety accidents. The purpose of daily maintenance is to keep lithium batteries in suitable environment, thus delaying the aging of batteries. In fact, one of the parameters of lithium battery design is the appropriate temperature. Relatively speaking, low temperature is not a big problem, but if placed at a higher temperature, the saying goes that things will go against each other, which will also cause safety problems. The idle state we are talking about is only in the normal environment. If we put lithium batteries in water or near the source of fire, it will be out of the topic of "maintenance". So, what should we do in the normal environment? Water aspect moisture-proof and heat aspect sun-proof. Therefore, the suitable environment for daily maintenance of lithium batteries should be four words: ventilation and shade. Whether lithium batteries are idle independently or in electrical appliances, these four words should be followed.
In the correct use of lithium batteries, the charging method of lithium batteries is the most important, because incorrect charging method will cause safety problems, and discharge and daily maintenance only affect the service life of lithium batteries, lithium batteries themselves are also a consumable material, no matter what measures we take, it can not avoid the ultimate loss of lithium batteries. Consumption, but we use the right way to delay its aging.
