What are the effects of moisture content on the performance of lithium iron phosphate battery packs

In the manufacturing process of lithium iron phosphate battery packs, many things must be strictly controlled, one is dust, the other is metal particles, and the third is moisture. Moisture has a huge impact on the lithium battery pack, and it will cause the following adverse consequences: 1. If the moisture is too high, the electrolyte will react with the moisture to generate a small amount of harmful gas, which will have an adverse effect on the environment of the injection room; this will also affect the electrolyte itself. The quality of the lithium iron phosphate battery pack makes the performance of the lithium iron phosphate battery pack poor, and it also makes the battery rivets rusty. 2. Moisture reacts with a component in the electrolyte to generate harmful gases. When there is enough moisture, the internal pressure of the battery will increase, which will cause the battery to be deformed by force. If it is a mobile phone battery, it appears as a bulging shell; when the internal pressure is high, the battery is dangerous, bursting causes the electrolyte to splash, and battery fragments are also easy to hurt people. 3. The internal water content of the lithium battery pack is too high; the effective components of the electrolyte are lost, and the lithium ions are also lost, causing an irreversible chemical reaction of the lithium ions on the negative electrode of the battery. When lithium ions are consumed, the energy of the battery is reduced. 4. Use a 26650 battery to power the electric drill. It can be used for 1 hour after the battery overflows. Because of the moisture inside the battery, it can only be used for 50 minutes. 5. When there is a lot of water inside the lithium battery pack, the electrolyte inside the battery reacts with water, and the product will be gas and hydrofluoric acid. Hydrofluoric acid is a very corrosive acid that can make the inside of the battery The metal parts corrode, which in turn causes the battery to eventually leak. If the battery leaks, the performance of the battery will drop rapidly, and the electrolyte will also corrode the user's machine, eventually causing more dangerous failures. 7. The internal pressure of the battery is too large. Moisture will react with a component in the electrolyte to generate harmful gases. When there is enough water, the pressure inside the battery becomes larger, causing the battery to be deformed by force. When the internal pressure is high, the battery is in danger, bursting causes the electrolyte to splash, and battery fragments are also easy to injure people.
