There are three key reasons for lithium battery bulging

　　There are three key reasons for the bulging of lithium batteries: The first reason: Manufacturer manufacturing process problems. Due to the large number of manufacturers, many manufacturers make the production and manufacturing environment difficult to save costs and use mechanical equipment that will be eliminated to replace these, thus making the battery coating ineffective. Uniformity, lithium battery electrolyte penetrates into dust particles, etc. These will cause the lithium battery pack to bulge when used by users, and even pose greater dangers. The second reason: users’ daily usage habits

　　The second one depends on the user himself. If the customer makes mistakes in the application of lithium-ion products, such as overcharging and over-discharging the battery, or extreme deterioration of the natural environment during continuous use of the environment, it will cause the lithium battery to bulge.

　　The third reason: long-term unnecessary and inappropriate storage. If various goods do not need long-term use, most of their original characteristics will be reduced, the battery will not be used for a long time, and the storage method is not good. It will not be applied and recharged when it is permanently exposed to the air. Since the gas is conductive to a certain extent, if it is in direct contact with the rechargeable battery for a long time, the short circuit fault will spread. Once the short circuit fault generates heat, part of the electrolyte solution will dissolve or even evaporate, resulting in a bulge.
