1. Overcharging leads to the expansion of lithium batteries. Overcharging can cause lithium molecules in the positive electrode material of the battery to completely enter the positive electrode material, resulting in the deformation and collapse of the original circular square in the positive electrode stage. This is the key reason for the decrease in capacity of lithium iron phosphate batteries. As the total number of lithium-ion batteries in the negative electrode stage increases, the excessive deposition of lithium molecules causes them to grow into dendritic crystals, leading to an increase in the number of lithium-ion batteries. Bulging caused by power loss
2. When the lithium liquid secondary battery is first charged, the metal electrode and the lithium battery electrolyte react on the solid-state high-performance liquid phase page to produce a passivation treatment layer. The passivation treatment film generated on the surface of the metal electrode can reasonably block the molecular structure of the lithium battery electrolyte, but lithium ions can be arbitrarily placed according to the passivation treatment layer and adsorbed by the resin, possessing the characteristics of a solid electrolyte.
Therefore, this passivation treatment film is called SEI. SEI movies are not static. During the entire battery charging process, there will be a small amount of conversion, mainly reversible conversion of some organic compounds. Excessive charging and discharging of the lithium iron phosphate battery pack leads to reversible ring breakage of the SEI plastic film. After maintaining the battery positive electrode material SEI, it collapsed, causing unpacking
3. The production and manufacturing level of lithium iron phosphate battery packs is related to the production and manufacturing level, and there are open-box conditions. Uneven coating of lithium battery pack and unsmooth production process
4. Even if left unused for a long time, the lithium iron phosphate battery pack will expand. Due to the conductivity of the gas to a certain extent, the charging and discharging time is too long, which is equivalent to direct contact between the positive and negative electrodes of the battery, leading to long-term short circuit faults.
