The safety of lithium battery on fire in the plane's power bank attracts attention

After an aircraft fires, the safety of lithium batteries has become the focus of attention. Recently, the mobile power supply (charger) of a passenger aircraft of my country Southern Airlines caught fire. Fortunately, the plane did not take off at that time, and the crew handled it quickly and properly without causing further disaster. With the world's low-carbon environmental protection trend, in recent years, my country's lithium battery market has ushered in a rare opening opportunity. Lithium batteries are everywhere in recharged cars, cars with energy stored in the body balance, mobile power supplies, etc. According to data from the Ministry of Industry and Information Technology, among the important products of my country's battery manufacturing industry, the cumulative output of lithium batteries reached 1.178.947 million units in 2017, a year-on-year increase of 31.25%. The export of battery manufacturing industry has delivered a total of 92.48 billion yuan, a year-on-year increase of 18.3%. However, repeated blows to the safe work of lithium batteries have also made everyone squeeze on lithium battery products. In addition to the above-mentioned fire work, recalls of lithium batteries are also frequently attacked. The US Consumer Product Safety Commission (CPSC) and six importers recently ordered the recall of 21,300 balance cars made in my country. The United States believes that the lithium battery packs on the six batches of balance vehicles sold in the United States may overheat during customer use, and there is a risk of smoke, fire or explosion. The company said it has received three reports of accidents, one of which caused a fire and caused $40,000 in damage to the house. Why are lithium batteries always in trouble? Experts in the industry say that under normal circumstances, good quality lithium batteries are safe, but the remaining lithium batteries are simply abnormal. The important reason is that the battery is overheated due to overcharging, and even the positive electrode Attacks on chemical changes, leading to fire or explosion; excessive emissions can also cause accidents. When the negative electrode contains an oxide, it reacts with the electrolyte and then releases heat. Some defective batteries may cause the above reaction due to impurities running into the electrolyte. Therefore, the inspection and quarantine department pays attention to quality problems such as battery charging overheating for lithium battery processing companies, and closely follows the quality standards of the exporting country; it also reminds processing companies such as balance bikes and mobile power sources to choose reliable suppliers, especially lithium battery packs. Choose carefully to effectively solve the risk of return, recall or fire and explosion caused by overheating of the battery pack. Chinanet believes that the Central Economic Work Conference has made a clear judgment that my country's economy has entered a new era. Its basic feature is that my country's economy has shifted from a high-speed rise stage to a high-quality development stage. This should be a period for lithium battery companies to do well at the time. In the next period of time, their operations will be basically followed, and product safety is undoubtedly the first.
