Correct use of lithium battery

Lithium battery is a more and more widely used energy storage conversion device, because its excellent electrochemical performance realizes the market application scenario of small medium large. When we talk about the correct use of lithium battery, we usually refer to the small application, i.e. consumer electronics, such as smart phones, laptops. Because large and medium-sized applications are based on small application technology, small applications have common characteristics, while large and medium-sized applications are much more complex. Generally, medium-sized applications are on new energy vehicles, which are generally called power batteries; large applications are usually on base stations, which are generally called energy storage batteries. So when we talk about "how to use lithium battery", it is in line with people's habit to limit lithium battery to small-scale applications.            The working principle of lithium battery is nothing more than charging to reserve energy, discharging into other energy and releasing. It is idle when neither charging nor discharging. Therefore, the correct use of lithium battery has three aspects: correct charging, correct discharging and correct maintenance.            Correct charging method of lithium battery            Grasp the time and prevent overcharge. Do the right thing at the right time. Although lithium battery itself has excellent electrochemical performance, however, any thing that deviates from the equilibrium state will have security risks. To be more specific,            1. When charging, charge. In the early days of smart phones, in order to protect their own interests, each mobile phone manufacturer often emphasized using the original charger (including charging line) to charge the electric equipment. Some manufacturers designed special data lines and did not support other chargers (including charging line). Later, with the application of smart phones and laptops becoming more and more widely, it's obvious that they are self-contained in this way, so now we have basically unified the standard, a kind of charger / wire can charge different brands and nature of electric 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. Under normal circumstances, when the power is too low, mobile phones and laptops will be reminded, and then you need to make up the power in time. Although the power is too low, it will not lead to a direct safety accident, but excessive use will cause damage to the battery structure over time.            2. Just fill it up. The internal part of lithium battery is also composed of many components. The new battery is OK. If it takes a long time, the function of which component may decline, so overcharge safety risk will occur. Samsung and apple were exposed in several typical accidents because the owner of the appliance put the mobile phone on the bedside to charge when sleeping, which finally led to combustion and explosion.            3. Don't use them all at once. I have experienced that it is very easy to feel the heat of mobile phone when using mobile phone while charging, especially when playing games. The truth is also very simple. Mobile phone is equal to playing two jobs at the same time, which makes it have to pay more than twice the labor force, and the body will naturally heat up.            Correct discharge method of lithium battery            Charge in time and prevent over discharge. Ordinary mobile phone users are not aware of the harm of over release, because there are no reports of safety accidents. Moreover, some people even think that regular deep discharge is good for battery performance maintenance. In fact, it is not, because the memory effect of lithium battery can be ignored, there is no deep discharge to eliminate the memory effect. Theoretically, the total cycle life of deep discharge of lithium battery will be longer, but the risk is that excessive discharge of battery will lead to low battery voltage, abnormal charging, sometimes it will take a long time to turn on, or even fail to turn on the machine. Since the two evils are lighter and the service life is shorter, it is better than not to use them. Therefore, it is advised that users of mobile phones and laptops should not often use black screens.            Correct maintenance of lithium battery            The temperature is suitable to prevent cold and hot. When the battery is idle, there is usually no safety accident. The purpose of daily maintenance is to put the battery in a suitable environment, so as to delay the aging of the battery. In fact, one of the parameters in the design of lithium battery is the appropriate temperature. Relatively speaking, the problem of low temperature is not big. But if it is put at a higher temperature, as the saying goes, extremes are bound to reverse, it will also cause safety problems. The idle state is just for the normal environment. If the lithium battery is put in the water or near the fire source, it will be out of the topic of "maintenance". What should we do in the normal environment? The water side is moisture-proof and the heat side is sun proof. Therefore, the appropriate environment for daily maintenance of lithium battery should be four words: ventilation and cool. These four words should be followed no matter whether the lithium battery is idle independently or in the electrical appliances.            In the correct use of lithium battery, the charging method of lithium battery is the most important, because the incorrect charging method will cause safety problems, while the discharge and daily maintenance only affect the service life of lithium battery, and lithium battery itself is a kind of consumable. No matter what method we take, we can not avoid its final loss, but we use the right method to delay its decline It's just old.
