What are the precautions for using lithium battery cells?

1. Matters needing attention in the use of batteries, including the protection of aluminum-plastic composite film, top sealing (edge u200bu200bsealing of the pole handle end), side sealing, and protection of the pole handle and measures to prevent mechanical impact and short circuit. 1. Aluminum-plastic composite film outer packaging protection: It is important to prevent being damaged by sharp parts. For this reason, the surrounding environment of the battery should be cleaned up from time to time, sharp parts are forbidden to touch or collide with the battery cell, and gloves can be worn when taking it to prevent the surface of the battery cell from being scratched by the fingernail. 2. Top sealing and side sealing protection: in order to prevent the top sealing and side sealing from being damaged and destroying the sealing effect, it is forbidden to bend the top sealing and side sealing; at the same time, the cell design must adopt reliable insulation isolation Measures to prevent short-circuiting of the negative electrode and the aluminum-plastic composite film. 2. After a battery cell is completed, the next step is to correctly combine the shell and the cell protection circuit module to make it a polymer battery. The precautions in this process are: 1. Shell design: (1) Enough machinery The strength is to prevent the battery core from mechanical damage by external forces. (2) When the battery core is installed in the shell, prevent the sharp edges and corners of the shell from scratching the battery core; (3) Prevent the aluminum-plastic composite film interlayer pure aluminum from contacting with the outside and short-circuiting. 2. The battery cell protection circuit must be designed: including the scientific setting of the maximum/minimum voltage, overcurrent protection, and battery unit (single cell) overcharge and overdischarge protection for battery cell combination use. 3. Monitoring water vapor in the manufacturing process of lithium batteries 1. The manufacturing process of processing battery cells is very sensitive to moisture. This challenging processing environment requires a water vapor detector with reliable performance and strong resistance to process by-products that may be present in the air. 2. In the process of lithium battery processing and manufacturing, the treatment of dry air is extremely important. It is important for the following three reasons: first, to prevent unnecessary chemical reactions such as fires and explosions; second, to prevent product quality problems; Third, grasp and control the costs associated with drying large amounts of air. At the same time, we choose well-known brand manufacturers to ensure long-term stability and efficient after-sales service capabilities to ensure that the quality of the products of processing manufacturers has a certain guarantee.
