Analyze the impact of water on lithium-ion batteries

The impact of water on lithium-ion batteries_Lithium-ion battery professional custom water has a greater impact on lithium-ion batteries, and importantly cause the following adverse consequences: 1. If the water content is too high, the electrolyte and water will react, causing trace harmful gases The environment of the injection chamber is adversely affected; this will also affect the quality of the electrolyte itself, make the battery performance worse, and cause the battery rivets to rust. 2. Water reacts with a component in the electrolyte, and harmful gases appear. When there is enough water, the pressure inside the battery will increase, causing strain and deformation of the battery. If it is a mobile phone battery, it is the case. When the internal pressure is too high, the battery is in danger of bursting, which is likely to cause electrolyte splash and battery fragments to injure people. 3. Too much water in the battery; the loss of active components in the electrolyte and the loss of lithium ions cause an irreversible chemical reaction of lithium ions in the negative plate of the battery. When lithium ions are consumed, the energy of the battery decreases. 4. Use 26650 battery for power supply. It could be used for 1 hour with a full charge, but because there is water in the battery, it can only be used for 50 minutes. 5. When there is too much water inside the battery, the electrolyte inside the battery reacts with the water, and gas and hydrofluoric acid appear (hydrofluoric acid is a very corrosive acid, which will make the metal parts inside the battery Corrosion occurs, causing the battery to eventually leak liquid). If the battery leaks, the performance of the battery drops rapidly, and the electrolyte corrodes the user's machine, leading to more dangerous failures.
