Briefly describe the assembly process and method of NiMH No.7 batteries
Whether in the digital or power application market, soft-pack lithium iron phosphate battery packs are becoming a very important technical route. Soft-pack batteries are actually batteries that use aluminum-plastic packaging film as packaging materials. The reason why soft-pack batteries can be thermally packaged is that they use aluminum-plastic packaging film. NiMH No.7 batteries are batteries that are covered with a layer of polymer shell on liquid lithium-ion batteries. They are structurally packaged with aluminum-plastic film. In the event of safety hazards, the soft-pack battery will only bulge and crack at most, so the overall safety performance is high. However, with the continuous development of the economy, people have also put forward higher requirements for soft-pack lithium battery packs. The existing lithium battery packs are complex to install and the process is cumbersome, and improvements need to be made. Soft-pack lithium iron phosphate battery assembly process and method Aluminum-plastic film molding process NiMH No.7 batteries can be designed into different sizes according to customer needs. When the external dimensions are designed, the corresponding mold needs to be opened to form the aluminum-plastic film. Generally, when the battery cell is thin, a single hole is selected, and when the battery cell is thick, a double hole is selected, because the deformation of one side is too large, which will exceed the deformation limit of the aluminum-plastic film and cause rupture. Top and side sealing process The top and side sealing process is the first packaging process of NiMH No.7 batteries. The top and side sealing actually includes two processes, top sealing and side sealing. First, the wound core should be placed in the punched hole, and then the packaging film should be folded in half along the dotted line. The top seal is to seal the pole ear, which is metal. After the formation, some batteries, especially thick batteries, may produce certain deformation due to the large internal stress. Therefore, some factories will set up a fixture shaping process after the formation, which is also called fixture baking. After the second seal is cut, it is necessary to trim and fold the edges, that is, cut the first and second edges to the appropriate width, and then fold them up to ensure that the width of the battery cell does not exceed the standard. After the folded edges, the battery cell can be put into the capacity division cabinet for capacity division, which is actually a capacity test to see whether the capacity of the battery cell reaches the specified minimum value. In principle, all cells need to be tested for capacity before leaving the factory to ensure that cells with unqualified capacity will not be delivered to customers. However, when the production volume of cells is large, some companies will do partial capacity testing to determine the qualified rate of the capacity of the cells in this batch by statistical probability. After the filling and sealing are completed, the cells need to be placed in a static state. According to the different processes, they can be divided into high-temperature static state and normal-temperature static state. The purpose of static state is to allow the injected electrolyte to fully infiltrate the electrode. Then the cells can be taken for formation. After capacity division, cells with qualified capacity will enter the post-process, including appearance inspection, yellow glue sticking, side voltage detection, pole ear transfer welding, etc., and several processes can be increased or decreased according to customer needs. Finally, there is OQC inspection, and then packaging and shipment. Note that it is still just cells up to this point. The cells will be sent to the Pack factory for further processing, including welding circuit boards, packaging, etc. The downstream of the Pack factory is various user manufacturers, such as Apple, Lenovo, and Huawei. They will take the battery Pack to install it in the terminal, and then it will come to our consumers. The production process of NiMH No.7 batteries is different from the other two types of commercial batteries in some aspects because the outer shell is made of aluminum-plastic film. For example, the packaging process of the aluminum-plastic film, and the shaping process during the formation process. The soft-pack lithium iron phosphate battery has a larger deformation space of the aluminum-plastic film, and will not explode in the case of thermal runaway like the steel-shell aluminum-shell battery cell; the shell is a layer of aluminum-plastic film, which is light in weight and has a small proportion of inactive parts. The weight of the soft-pack battery is 40% lighter than that of the steel-shell lithium battery of the same capacity, and 20% lighter than that of the aluminum-shell battery.
