Emergency treatment method of lithium battery

Source: 2020 - 04 - 01 15:01 hits: emergency treatment for long-term storage lithium batteries may cause leakage, rust, flatulent phenomenon; Such as improper operation, may appear the phenomenon such as fever, burning, blasting, its processing method is as follows: rust treatment: it is generally believed to cylindrical lithium-ion batteries, Polymer lithium battery does not exist this kind of phenomenon) Early, small rust does not affect the function of the lithium battery, can be normal use. Such as serious rust ( Such as cap) Affect battery and leak sealing function, it is necessary for waste disposal. Solution leakage or bulging: refers to the leakage of battery electrolyte leakage, tend to have a pungent odor, electrolyte has strong corrosion effect will cause the battery maintenance board component is damaged, such as polymer lithium battery can attack the bulging. Leakage and bulge out it is necessary to select batteries, waste disposal. Under the condition of normal temperature and high humidity environment, the battery will not happen against mildew, discoloration, assuming that attack leak will attack this kind of undesirable phenomenon. Heat treatment: the charge and discharge ( Using the state) Will be fever, but temperature under 60 degrees. Battery internal or external short circuit state, the temperature can reach baidu baidu or Numbers. At this point, it is necessary to isolate the battery. Put it in the sand. When the battery temperature drop to normal temperature, will be scrapped. Burning or blasting process: assume that burned or blasting phenomenon, is very dangerous, it is necessary to stay away from; General battery fire burning will not attack, because of high temperature inflammable goods or packaging box, under the premise of should be protected, such as a little or battery burning or blasting storage: use sand blasting battery cover burn or directly. Using large area burn powder recovery and saving, prevent water saving, because water will cause the battery short circuit. Long storage processing method is generally not advocated lithium battery stored for more than two years, because the longer the storage time, battery capacity loss is more serious, Lead to equipment shorter time) 。 In accordance with point 2 'long-term storage, generally can be managed two years or three years, in addition to capacity attenuation generally no other function, but assembly instrument or equipment will charge and discharge time is short, Use the time) , usually say 'all electrical fast without electricity, when the battery life is less than the specified customer requirements, by the customer or the use of nonconforming or scrap.
