Analysis of emergency treatment methods for lithium batteries

Long-term storage of lithium batteries may cause leakage, rust, and flatulence; if improper operation, heat, burns, explosions, etc. may occur. The treatment methods are as follows: Rust treatment: Generally, lithium batteries are considered to be cylindrical (polymer lithium This phenomenon does not exist in the battery). In the initial stage, small rust will not affect the function of the lithium battery and can be used normally. If the rust is severe (such as bottle cap), it will affect the sealing function and leakage of the battery, and it is necessary to carry out waste disposal. Solution leakage or bulging: Leakage refers to the electrolyte leakage of the battery, which generally has a pungent odor. The strong corrosion of the electrolyte will cause damage to the battery maintenance board components, such as polymer lithium batteries will attack and swell shape. Leaking and bulging batteries must be selected and disposed of. Under normal temperature and high humidity environmental conditions, the battery will not attack, mold, or discolor, and it will attack this undesirable phenomenon if it is attacked and leaked. Heat treatment: It will generate heat during charge and discharge (under use), but the temperature is generally below 60 degrees. In the state of internal or external short circuit of the battery, the temperature can reach hundreds of degrees or hundreds of degrees. At this time, it is necessary to isolate the battery. Put it in the sand. When the battery temperature drops to normal temperature, it will be scrapped. Incineration or blasting treatment: Assuming that an incineration or blasting phenomenon occurs, it is very dangerous and it is necessary to stay away; generally, the burning of batteries will not attack and fire, because high-temperature flammable items or packaging boxes, such as one or a few batteries, are properly protected. Burning or blasting preservation method: directly use sand to cover the burning or blasting battery. Assuming that large-area incineration uses dry powder resuscitators to save water and prevent water saving, because water will cause battery short circuit. Ultra-long storage processing methods generally do not advocate the storage time of lithium batteries for more than two years, because the longer the storage time, the more serious the battery capacity loss (resulting in the shortening of equipment time). According to point 2 long-term storage, it can generally be hosted for two or three years.Except for capacity attenuation, there is generally no other function, but the assembled instrument or equipment will have a short charging and discharging time (usage time). It is usually said that there will be no electricity after charging. When the battery life is less than the specified customer demand, it is produced by the customer or using unqualified products or scrap products.
