Can bulging or leaking batteries work? How to deal with it?

Because the polymer battery contains electrolyte, it is composed of organic solvent (usually carbonate) and electrolyte lithium salt lithium hexafluorophosphate (LiPF6). The electrolyte has strong water absorption. LiPF6 reacts with water in the air to form hydrofluoric acid. It is corrosive and can cause damage to human skin, eyes, etc. Therefore, in the case of swelling or leakage of the battery, you should prevent direct contact with the battery with your hands to prevent skin corrosion. When the battery bulges and leaks, chemical reactions have occurred inside the battery, and the battery performance has deteriorated. At this time, the battery may be charged and discharged, the battery may further swell, and there may be the possibility of burning, so swelling or leakage occurs in the battery In this case, the battery should also be prevented from being charged and discharged. The correct way is to separate the battery packaging with plastic bags or acid-resistant packaging, and hand it over to a professional battery recycling company for recycling. Battery pack replacement batteries Polymer lithium-ion single cells can be combined into battery packs with different voltages and capacities through different series/parallel modes. The rated voltage of a single battery is 3.7V. Different monomers should be paired according to the voltage, internal resistance, and capacity of the single battery. The performance of each monomer should be matched, so that the performance of the battery pack can be brought into full play. Because the pairing of single batteries requires professional equipment and instruments to measure the performance of single batteries; at the same time, the assembler must have certain professional knowledge, otherwise it will easily cause damage to the battery during the assembly process. If the monomers are connected in series or parallel connection improperly , Bad conditions such as false welding, short circuit, puncture, etc., when the battery pack is in use, may have serious consequences such as short battery life, battery swelling, short life, and burning.
