What is the reason for the drumming of lithium batteries?

Reason 1: Lithium batteries have a long use time and their functions are aging. Lithium battery packs also have a service life. If the battery is used for longer than that, the materials and reactions inside the battery will age or change, which is very dangerous. Therefore, if the battery is used for too long, the battery should be recycled properly. Reason 2: The battery charging time is often too long, and it generates heat. When the mobile phone is charged, it will cause the lithium battery to chemically react and generate heat. The standard lithium battery rechargeable battery can be charged with a small current for 14 hours to make the mobile phone power reach 95%. However, because modern people can't wait for such a long time, current manufacturers have increased the charging current. This can speed up the charging time, but it also accelerates the internal chemical reaction of the lithium battery. Excessive heat will cause the internal heat to overheat, and the lithium battery shell can not withstand the internal overheating pressure and the shell will expand. Reason three: the quality of the power lithium battery itself. If the water content of lithium batteries is not well controlled during the manufacturing process, gas will be produced during formation, and the gas composition will be very complicated. But there is usually a process of exhausting, and sealing after exhausting, laser welding of aluminum shell, high temperature fusion of PP layer of soft-coated polymer. However, there are also illegal businesses on the market that sell lithium battery products that are of poor quality, so consumers must go to regular stores to buy battery products. Therefore, in daily life, we should develop good charging habits to reduce the probability of battery bulging and to extend the service life of the battery. Also beware of the danger of improper use.
