Lithium battery is a stored energy conversion device is more and more widely, because of its excellent electrochemical performance to achieve the small, medium, large such a market application scenario of keeping pace with The Times, when we are talking about the correct way of using the lithium battery, usually a small application aspects, namely, consumer electronics, such as smart phones, laptops. Because medium and large application is based on small application technology, so small application has common characteristics, and medium and large application is much more complex, usually, medium application is on new energy vehicles, generally we call it power battery; The big applications are on base stations, which we call energy storage batteries. So when we talk about "how to use lithium batteries," it's customary to limit lithium batteries to small applications.

 

 

 

Lithium batteries work by charging to store energy, discharging to convert it into other energy and releasing it. In neither charge nor discharge in the idle state, therefore, the correct use of lithium battery on its big aspects that there are three: correct charge, correct discharge, correct maintenance.

 

 

 

Correct charging method for lithium battery

 

 

 

Seize the time to prevent overcharge. Do the right thing at the right time. Although lithium batteries themselves have excellent electrochemical performance, however, anything that deviates from the equilibrium state will have a safety hazard. In detail,

 

 

 

1. When it's full, it's full. At the early stage of the emergence of smart phones, each mobile phone manufacturer, out of the original intention of protecting their own interests, often emphasizes the use of original charger (including charging cable) to charge electrical equipment, some manufacturers design special data cable, and do not support other chargers (including charging cable). Later, as smartphones and laptops became more and more widely used, it became clear that this was a self-imposed barrier, so now everyone has basically standardized on one charger/cable that can charge different brands and properties of electric appliances. Charging convenience, users should pay attention to a problem is to try to keep the battery with normal use of power. Under normal circumstances, when the power is too low, mobile phone and laptop will be reminded, then you need to timely recharge, although the low power will not lead to a direct safety accident, but overuse, over time will cause damage to the battery structure.

 

 

 

2, full can be. Lithium battery cell is composed of many components, the new battery is ok, if it is used for a long time, who knows which components function will decline, so there will be overcharge safety risk. Several of the typical incidents exposed by samsung and apple have been caused by the owners of electrical appliances leaving their phones at the bedside to recharge while they slept, causing them to burn and explode.

 

 

 

3. Don't do two things at once. The author has experience, while charging the use of mobile phones, especially when playing games is extremely easy to feel the heat of the phone, the reason is 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, the body will naturally heat.

 

 

 

Correct discharge method of lithium battery

 

 

 

Timely charging, anti - release. Ordinary mobile phone users are unaware of the dangers of over-release, as there are usually no reports of safety incidents. Moreover, some even argue that regular deep discharges are good for maintaining battery performance. 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 speaking, the total cycle life of deep discharge of lithium battery will be larger, but the risk is that excessive discharge of battery will lead to the battery voltage is too low, can not be charged normally, sometimes it will take a long time to turn on, even can not open the machine. Choose the lesser of two evils, shorter life is better than no use, so we advise the majority of mobile phone and laptop users do not often use black screen.

 

 

 

Proper maintenance of lithium batteries

 

 

 

The temperature is suitable, anti - heat. When idle, lithium batteries usually do not occur safety accidents, the purpose of daily maintenance is to make lithium batteries placed in the appropriate environment, thus delaying the aging of the battery. In fact, one of the parameters of lithium battery design is the appropriate temperature, relatively speaking, the temperature is not a problem, but if put in a higher temperature, as the saying goes, things will reverse, also will produce safety problems. If you put a lithium battery in water or near a fire source, it's out of the question of maintenance. So what do you do in a normal environment? The water side is moisture-proof and the heat side is sun-proof. Therefore, lithium battery daily maintenance of the appropriate environment should be four words: ventilation, cool. Whether the lithium battery is independent idle or in the electrical appliances to be used, should follow these four words.

 

 

 

In the correct way of using the lithium batteries, lithium battery charging method is one of the most important, because not correct charging method will lead to security issues, and the discharge and the influence of daily maintenance is only the service life of lithium batteries, lithium battery itself is also a kind of material, no matter what way we can avoid the loss of it in the end, we just use the right method, delay the aging.
