Packaging and design requirements for finished lithium batteries

　　PVC heat sealing: The specific outer shell packaging form used for the battery pack mainly depends on the specific needs of the customer's product. For packaging forms using PVC heat sealing, it is generally suitable for situations where the number of battery cells in series is not large and the overall weight is relatively light (≤ 2kg). However, for battery packs with an overall weight of ≥ 1kg, fixed brackets need to be added between the battery cells, and fiberglass panels need to be added to protect the periphery before using PVC heat sealing.

　　Plastic: Using a plastic shell is mainly because after different battery packs are shaped, the shell involved may need to be molded, and the mold cost is a significant expense. If the product is not shaped in the early stage of development, a hand board shell can be used for sampling (the hand board strength is not as strong as the material strength after molding). Different requirements for the material and process of the shell (especially with three prevention requirements) can also affect the cost.

　　Metal: Metal shells are also the same as plastic shells. Before the product is finalized or there is not much demand for quantity, it is recommended to use sheet metal sample making. This is mainly because the lead time for sample making is short. If the batch size is large, it is also recommended to open the mold. For metal shells with waterproof grade requirements, it will greatly affect the cost, and for metal shells with special materials such as aluminum alloy, the cost will be higher.

　　The cost of lithium batteries mainly consists of battery cells, PCM, and structural components, plus the company's PACK fees, aging fees, management fees, etc. At the same time, due to the different requirements for product technology difficulty, procurement quantity, and defect rate, the price of lithium batteries will also vary greatly Our experienced R&D team is constantly monitoring the latest developments and applications of lithium batteries in various fields, and continuously developing "the most front-end, advanced, safe, and stable" lithium battery solutions for customers.
