Model aircraft lithium battery discharge bulge how repair?

Source: 2020 - 03 - 29 16:08 hits: lithium battery was blowing of model aircraft, can repair? Drum drum out the cause of the lithium-ion batteries, lithium-ion battery pack that can also be used? In recent years, lithium-ion batteries for its high energy ratio and high security has been widely used in the market. Although the safety of the lithium battery is much higher than lead-acid batteries, but if use undeserved or manufacturing level is not high, also has certain security hidden danger, such as out of the problem. What is the cause of the lithium battery bumps? The main cause of lithium battery bulge has two, one is factory manufacturing problems and manufacturing environment, manufacturing equipment old, make a battery coating uneven, electrolyte mixed with dust particles. All of which may make the lithium battery packaging when users use appears ballooning, appear even bigger risks. Another reason is the user itself, if the user in the use of improper use of lithium battery products, such as overcharge discharge, or in extreme environment continue to use, is likely to make the lithium battery. In addition to the two main reasons, there is a less common cause. That is to say, the battery is not used for a long time, then there is no better save processing. When it is exposed to the air after a long period of time, you don't have to, and electricity is full. Because the air is conductive to a certain extent, long discharge equivalent to direct contact with the battery of the positive and negative, is a chronic short circuit. The expansion of the lithium battery is the first principle, similar to a short circuit inside the battery explosion violent reaction, produce a lot of heat, cause the electrolyte decomposition and evaporation, lithium battery. Lithium battery packaging can continue to use? When lithium-ion battery pack bulge problem, it is best not to continue to use the defective batteries. Due to the expansion of the battery, when inflation to a certain extent could cause an explosion, very dangerous. For the sake of their own safety, had better be in found that bulge when lithium battery replacement as soon as possible. Bulge lithium-ion battery pack should be how to deal with? The expansion of the lithium-ion battery pack for the user's safety, is not suitable to continue to use, due to its internal crystallization, without too much capacity can be used. Lithium battery bag generally need professional recycling, in order to avoid pollution to the environment, so it's best to discard it to the professional processing of lithium battery bag. If there is no such a place nearby, the best thing to do is throw it into the waste battery recycling bins. Under normal circumstances, the purchase of normal manufacturer production of lithium battery pack, in use process pay attention to the method of use, can prevent bulge problem to a great extent.
