How to make a self-made lithium battery pack?

How to make a lithium battery pack? Lithium battery pack refers to the need to connect lithium batteries in series or parallel in order to meet a certain requirement. Of course, many people choose to make lithium battery packs by themselves in order to save money. Lithium battery pack production process: battery cell detection and matching group, according to the required voltage capacity and connected in series. Install protection circuit. Finished product inspection. package. Just these procedures. The whole set of equipment and tools can be completed at about 20,000 yuan. Lithium battery packaging technology is very strict and complicated. Here we can only briefly analyze a few of the important processes: Method 1. Special solvents and binders for pulping are mixed with powdered positive and negative active materials respectively, and then processed at high speed. After stirring uniformly, a slurry-like positive and negative material is prepared. Method 2: Coating The prepared slurry is uniformly coated on the surface of the metal foil and dried to form positive and negative pole pieces respectively. Method 3. Assemble according to the order of positive electrode sheet-diaphragm-negative electrode sheet-diaphragm from top to bottom. The battery pole core is formed by winding, and then through the process of injecting electrolyte and sealing to complete the battery. Assembling process to make finished battery. Method 4: Chemicals uses special battery charging and discharging equipment to perform charging and discharging tests on finished batteries, each battery is tested, and qualified finished lithium battery packs are screened out before leaving the factory.
