What are the types of lithium battery PACK production?

1. Prevent the short circuit of the lithium battery cell. Prevent the short circuit of the lithium battery cell. Do not place the cell next to conductive materials or conductive tools. Prevent the positive and negative overlap of the cell. 2. The positive electrode aluminum tape of the lithium battery is protected by the tensile force of the aluminum sheet itself. It is 1KG, so the aluminum sheet is generally not allowed to bear excessive tension alone during production; when aluminum is connected to nickel, prevent excessive welding or false welding, so as to prevent the aluminum strip from being welded to the nickel strip to reach the tensile strength that should be In the case of soft, thin, and easy to break, in order to ensure the quality of the product, when the aluminum sheet is connected to the nickel tape, the positive aluminum tape is generally produced by back-folding and in-folding, and double-sided tape is applied to protect the tabs from external tension. Impact; the protection of the positive electrode aluminum tape of the lithium battery 3. Pay attention to the length when folding the positive and negative electrodes of the lithium battery. When welding the nickel tape with the inward folding process, the length of the bent aluminum sheet or the nickel tape shall not exceed the length of the battery cell groove to avoid being too long. Pressure punctures the insulating glue and the cell packaging film, causing the cell to leak. Lithium battery positive aluminum tape protection 4. Lithium battery cell outer packaging film protection is strictly prohibited from scratching its surface with sharp objects. To prevent scratches on lithium battery cells, you should work with finger cots to prevent scratches on lithium battery cells. Prevent the use of tweezers and other sharp tools to touch the surface of the battery core, and prevent leakage of the battery by piercing the battery package. Prevent contact with the surface of the lithium battery cell with a sharp object such as tweezers, and prevent leakage of the cell package by puncturing the cell package. 5. Anti-impact protection of the battery cell must be very careful in the process of transportation, storage, use, etc. The battery cell cannot be squeezed or hit by heavy objects; when assembling the battery, you should prevent the battery cell's periphery and prevent the internal diaphragm of the battery cell. The rupture causes a short or even short circuit. 6. Assembling environment for lithium battery cells, pay attention to the cleanliness of the work surface. Keep the work surface clean to prevent nickel tape, tin slag and other foreign objects from piercing the cell. 7. The protective tab welding or tin immersion time during the welding of lithium battery tabs should be as short as possible, generally within 3 seconds at 360°C. The welding time of the lithium battery should not be too long, so as to avoid scalding the lugs and causing liquid leakage. It is not advisable to bring decorative items such as rings on your hands. So as not to scratch the battery core. 8. In order to protect the lugs, tin can be immersed before welding. Holding the battery core immersed in tin is likely to cause a short circuit, and the aluminum strip and the nickel strip are immersed separately.
