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 large and medium-sized applications are based on small application technology, so small applications have common characteristics, and large and medium-sized applications are much more complex, usually, medium-sized applications are in new energy vehicles, generally we call them power batteries; The big applications are usually in base stations, what we call energy storage batteries. So when we talk about "lithium battery use method", the lithium battery is limited to the small application domain conforms to people's customary understanding.
Lithium-ion batteries work by charging them to store energy, then discharging them into other energy and releasing them. In neither charge nor discharge in idle state, therefore, the correct use of lithium battery on its big aspects say there are three: correct charge, correct discharge, correct maintenance.
Correct charging method for lithium battery
Grasp the time and prevent overcharging. Do the right thing at the right time. Although lithium batteries themselves have excellent electrochemical performance, any thing that deviates from the equilibrium state will have safety risks. In detail,
1. As soon as the charger is charged, so soon as the charger is charged. In the early stage of the emergence of smart phones, every mobile phone manufacturer, in order to protect their own interests, often emphasize the use of original chargers (including charging cables) to charge electrical equipment, some manufacturers design special data cables, and do not support other chargers (including charging cables). Later, as smartphones and laptops became more and more widely used, it became obvious that this was self-inflicted, so now there is basically a unified standard, one charger/cable that can charge different brands and properties of electrical appliances. Charging is convenient, users should pay attention to a problem is to try to keep the battery with normal use of power. Under normal circumstances, when the battery is too low, the mobile phone and laptop will alert you, then you need to recharge in time, although too low battery does not cause a direct safety incident, but overuse, over time can cause damage to the battery structure.
2, can be filled. The inner core of lithium battery is also composed of many components. The new battery is ok. If it is used for a long time, the function of which components will decline, so there will be overcharging safety risk. Typical accidents involving Samsung and Apple have been exposed as a result of owners putting their phones on the bed to charge while sleeping, which eventually caused combustion and explosions.
Don't do two things at once. The author has experience, while charging while using mobile phone, especially when playing games is very easy to feel mobile phone fever, the truth is also very simple, mobile phone is equal to play two jobs at the same time, which makes it have to pay more labor, the body will naturally heat.
Correct discharge method of lithium battery
Charge in time to prevent overrelease. The average mobile phone user is not aware of the dangers of over-exposure, as there are usually no reported safety incidents. Moreover, it has even been suggested that regular deep discharges are beneficial 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 the deep discharge of lithium batteries will be larger, but the risk is that excessive discharge of the battery will lead to too low battery voltage, can not charge normally, sometimes it will take a long time to turn on, or even can not open the machine. Choose the light of two evils, the service life of a little bit is better than not to use, so advise the majority of mobile phone and laptop users do not often use black screen.
Proper maintenance of lithium batteries
Suitable temperature, prevent hot and cold. When idle, lithium batteries usually do not have safety accidents, the purpose of daily maintenance is to make lithium batteries in a suitable environment, so as to delay the aging of the battery. In fact, there is a suitable temperature in the design of lithium battery parameters, relatively speaking, low temperature is not a big problem, but if it is put at a higher temperature, as the saying goes, too much will have the opposite effect, it will also produce safety problems. We say that the idle state is only in terms of the normal environment, if the lithium battery is put in water or close to the fire that has been removed from the topic of "maintenance", so, in the normal environment to do what? Moisture protection and heat protection from sun exposure. Therefore, the suitable environment for daily maintenance of lithium battery should be four words: ventilation and shade. These four words should be followed regardless of whether lithium batteries are idle or used in electrical appliances.
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.
