Misunderstandings that endanger the life of lithium batteries

Mobile power has now become an indispensable digital device for most customers in their daily lives. Whether in the subway to and from get off work, or on the flight, train or long-distance car to the destination, we can see it. Figure, as we enjoy the convenience of the mobile power supply, its safety function is also well known to everyone. After all, the internal lithium battery cell will end the life of the mobile power supply early due to people's mistaken operation. Because most mobile power supplies on the market today are composed of lithium batteries (including 18650 or polymer), circuit boards and shells, and the three important parts are combined. In people’s traditional impression, when it comes to the safety of lithium batteries, Will naturally think of all kinds of explosions. So today we will talk about Ruan's correct operation of the mobile power in daily use, to guard against the various methods of death that appear in the lithium battery inside the mobile power. Because the lithium battery inside the mobile power supply is proportional to the weight, and some mobile power supplies with a capacity of tens of thousands of mAh have their own weight of more than 200g, plus the use of plastic (11230, -55.00, -0.49%) shell planning, in In the event of a fall, it is easy to break the product shell. Especially the low-cost and inferior power bank, the shell is made of very fragile recycled plastic. At present, there are many electronic products on the market that are very well planned for the maintenance of lithium batteries. For example, Apple’s iPad, when the temperature of the internal sensor test is too low, it will automatically prevent the charging operation, so as to be wary of charging in a low temperature environment. The damage to the battery occurs. Therefore, the same is the lithium battery. When we use the mobile power supply in our daily life, we should also try to beware of the situation that the ambient temperature is too low or too high, so that we can be wary of the sudden decrease in capacity or the permanent damage of the battery, and the situation that it will be used directly appear. I believe that many people have heard about the explosive news about lithium batteries. With the widespread use of lithium batteries in recent years, more and more electronic products almost use it to replace traditional batteries. When the lithium battery first appeared, because of technical reasons, its safety function was very low, and the fire and explosion were very common. However, through the continuous improvement of technology, the current lithium battery has a higher safety performance. However, puncture or fire can still cause smoke or explosion of the lithium battery. Therefore, when we need to throw away the mobile power supply, we must not throw it into the fire source or throw it away together with the daily waste. A certain degree of puncture, crushing and fire will cause the danger of smoke or explosion, and pose a serious environmental problem. Damage. It is worth noting that the use of inferior chargers will also have a certain chance of causing the explosion of lithium batteries. Compared with the discharge process, lithium batteries are the most dangerous when charging, which is why most mobile phone explosions are caused by explosions. It happened while charging. Therefore, we should buy reliable or original mobile phone chargers for charging in daily use. Because of the chemical characteristics of lithium batteries, even if they are left unused, the voltage will slowly drop. This is what we often call the self-discharge phenomenon of lithium batteries. In addition, the self-discharge phenomenon of the lithium batteries inside the mobile power supply is more significant, because most of the batteries inside the mobile power supply are directly soldered to the circuit board, and customers cannot take out the batteries and store them separately when they are not in use. , And the standby or hibernation circuit on the circuit board has been in operation, and the power will be exhausted overnight. Although the internal battery maintenance circuit of the mobile power supply will automatically block the circuit when the battery power (voltage) drops to a certain value to reduce the self-loss of the power, the low voltage settings of the maintenance circuit of the mobile power supply on the market are different. Therefore, we should try to beware of the mobile power supply when it prompts the lack of power. For a long time (three to six months or longer, depending on the self-loss of the mobile power supply), it will be over-discharged at this moment. Straightness leads to a sharp drop in battery cell capacity. Therefore, after we buy the power bank, charging and discharging it every time is the best way to extend its life.
