Four 'misunderstandings' that endanger the life of lithium batteries

Four misunderstandings that endanger the life of lithium batteries. Mobile power has become the most indispensable digital device for customers in daily life. Whether it is commuting to and from the subway, it is still a flight, train or long-distance bus to the destination, we can see Figure, enjoy our mobile power supply brings us convenience, safety performance also knows that everyone wants, the human error of its internal lithium battery under various uses, will make the mobile power all come to an end early. Most mobile power sources on the market today are lithium batteries (including 18650 or polymer). The three important parts of the combination of circuit boards and casings are in people's traditional impression. When it comes to the safety of lithium batteries, it will naturally explode. related. So today we are going to talk about the correct operation of the mobile power supply in daily use by Ann, and the prevention of various deaths caused by the internal lithium battery to the mobile power supply. Because the lithium battery inside the mobile power supply is directly proportional to the weight, some mobile power supplies with a capacity of tens of thousands of milliamperes themselves weigh more than 200 grams. According to the plan of using the plastic shell, when the product has liquid droplets, it is easy to break the product shell. In particular, it is a cheap alternative mobile power source, the shell is made of very fragile recycled plastic. Assuming that the internal insulation planning of a mobile power supply is not in place, and the cables between the battery and the circuit board solder joints are loose, there is a simple drop of desoldering, and catch up with the important circuit boards, circuit boards and batteries, wires and other bearings of the battery maintenance circuit plan. Contact, there may be a direct short-circuit state. And some mobile power supplies with relatively thick work generally use some fixing methods to firmly fix each wire of the battery, and the appropriate wire length and ultra-fixed treatment can further enhance the internal insulation effect. However, for most customers, it is difficult to know the internal structure and insulation effect of the mobile power supply, so when we use the mobile power supply in our daily life, the first thing to pay attention to is to prevent the mobile power supply from falling. What is death by temperature difference? Its working temperature is too high or too low, causing the internal lithium battery capacity of the mobile power supply to decrease. The working temperature of dadu lithium battery is -20C-60C, and the best working temperature is 0C-40C. Lithium batteries with different positive electrode data also have different operating temperatures and optimal operating temperatures.
