What changes will moisture cause to lithium-ion batteries?

If the moisture is too high, the electrolyte reacts with the moisture to generate a small amount of harmful gas, which will have a negative impact on the environment of the injection room; this will also affect the quality of the electrolyte itself, make the battery performance poor, and make the battery rivets rusty. Moisture reacts with a component in the electrolyte to generate harmful gases. When there is enough moisture, the pressure inside the battery will increase, which will cause the battery to be deformed by force. If it is a mobile phone battery, it will behave as a bulging shell; when the internal pressure is high, the battery is dangerous, bursting and splashing the electrolyte, and battery fragments are also easy to hurt people. The internal moisture of the battery is too high; the effective components of the electrolyte are lost, and the lithium is also lost, causing an irreversible chemical reaction of lithium on the negative electrode of the battery. When lithium is consumed, the energy of the battery is reduced. The electric drill is powered by a 26650 battery. It can be used for 1 hour after being fully charged. Because of the moisture inside the battery, it can only be used for 50 minutes. When there is a lot of water inside the battery, the electrolyte inside the battery reacts with water, and the product will be gas and hydrofluoric acid (hydrofluoric acid is a very corrosive acid, which can corrode the metal parts inside the battery If the battery leaks, the performance of the battery will drop rapidly, and the electrolyte will corrode the user’s machine and eventually cause more dangerous failures.
