Lithium battery is an energy storage conversion device which to use widely . Because of its excellent electrochemical performance, it realizes the market application scenario of small, medium and large-scale.
When we talk about the correct use of lithium batteries, we usually refer to small applications, that is, consumer electronics, such as smart phones and laptops. Because large and medium-sized applications are based on small application technology, small applications have common characteristics. Large and medium-sized applications are much more complex. Usually, medium-sized applications are used in new energy vehicles, which are generally called power batteries. Large scale applications are usually on base stations, which are generally called energy storage batteries. Therefore, when we talk about the “use method of lithium battery”, it is in line with people’s customary understanding to limit lithium battery to small application fields.
The working principle of lithium battery is nothing more than charging to reserve energy, discharging into other energy and releasing it. It is idle when it is neither charged nor discharged. Therefore, the correct use method of lithium battery: correct charging, correct discharge and correct maintenance.
Correct charging method of lithium battery
Grasp the time to prevent overcharge
Do the right thing at the right time. Although lithium battery itself has excellent electrochemical performance, any thing that deviates from the equilibrium state will have potential safety hazards.
Timely charging
In the early stage of the emergence of smart phones, each mobile phone manufacturer, out of the original intention of protecting their own interests, often emphasized the use of original chargers to charge electric equipment. Some manufacturers designed special data lines and did not support other chargers. Later, with the increasing application of smart phones and laptops, it is obviously self binding to continue like this, so now we have basically unified the standard, and a charger / line can charge electric appliances of different brands and properties. Charging is convenient. One problem 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, the mobile phone and laptop will have a reminder. At this time, you need to replenish the power in time. Although low power will not lead to direct safety accidents, excessive use will damage the battery structure over time.
Fill it up
The lithium battery cell is also composed of many components. The new battery is OK. If it is used for a long time, maybe the function of any component will decline, so there will be overcharge safety risk. Several typical accidents exposed by Samsung and apple were caused by the owner of the electric appliance putting his mobile phone at the head of the bed to charge while sleeping, which finally led to combustion and explosion.
Never use two things at once
While charging and using the mobile phone, especially when playing games, it is very easy to feel that the mobile phone is hot. The reason is also very simple. The mobile phone is equal to working 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 of lithium battery
Charge in time to prevent over discharge.
Ordinary mobile phone users are not aware of the harm of over discharge, because there are usually no reports of safety accidents. Moreover, some people even think that regular deep discharge is good for the maintenance of battery performance. In fact, it is not because the memory effect of lithium battery is negligible, and there is no saying that deep discharge eliminates the memory effect. Theoretically, the total cycle life of lithium battery with deep discharge will be greater. However, the risk is that excessive battery discharge will lead to low battery voltage and failure to charge normally. Sometimes it takes a long time to start the machine, and it can’t even start the machine. The lesser of the two evils, the shorter service life is better than not being used. Therefore, the majority of mobile phone and laptop users are advised not to often use the black screen.
Correct maintenance of lithium battery
The temperature is suitable to prevent cold and heat.
When idle, lithium batteries usually do not have safety accidents. The purpose of daily maintenance is to put the lithium battery in a suitable environment, so as to delay the aging of the battery. In fact, one of the parameters of lithium battery design is the appropriate temperature. Relatively speaking, it is not a problem if the temperature is low, but if it is placed at a higher temperature, as the saying goes, when things reach the extreme, they will turn against each other, which will also produce safety problems. We are talking about the idle state 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”. The water is moisture-proof and the heat is sun proof. Therefore, the suitable environment for daily maintenance of lithium battery should be four words: ventilation and shade. These four words shall be followed whether the lithium battery is idle independently or ready for use in electrical appliances.
In the correct use of lithium battery, lithium battery charging method is the most important. Because incorrect charging method will cause safety problems, and discharge and daily maintenance only affect the service life of lithium battery. Lithium battery itself is also a consumable. No matter what measures we take, we can’t avoid its final loss, but we use the correct method to delay its aging.
