Polymer lithium battery manufacturing process

Source: 2020 - 04 - 10 neither hits: time general technological process of polymer lithium-ion battery production process: mixed pulp & gt; Coating and drying b> Coating baking & gt; Roller pressure b> Cutting & gt; Article & gt; Winding & gt; The insulation test mixed solvent pulping and adhesive respectively mixed with positive and negative active material. After high speed stirring evenly, the slurry is made the cathode material. 2, dry coating will paste evenly applied to the foil surface and make it dry process. 3, roller pressure through the roller compaction pressure straightening and cutting are anode materials. Article 4, cut the positive and negative material automatic cutting length comply with film and batteries specifications and design requirements. 5, pole piece according to the whole volume pole, the technical parameters of automatic cutting, welding, adhesive tape. 6, winding with diaphragm paper to separate the positive and negative pills, along the axis core automatic winding into the battery, and put a stop to take. Insulation test 1 positive and negative after diaphragm winding separately; Consists of the battery, and the insulation performance was tested. Viii. Package 1 bare battery with perforation of aluminum-plastic composite membrane, to seal the top of the battery. 9. Enclose 2 seal open on the left side of the of the battery. 10. Insulation test the battery 2 ears and aluminum-plastic composite membrane insulation performance of 11. Insulation test 3 seal after the test the insulation performance of the battery. 12. Vacuum drying using vacuum dry battery, the battery fully discharge after injection of moisture, guarantee the quality of the battery. 13. Liquid jet injection battery electrolyte injection port, the relative humidity in the oven dry gloves should be less than 1% RH. After sealing 3 filled with electrolyte, sealed injection port, after the completion of the glove box is put in the dry. 15. Check test battery resistance and injection meets the design requirements. In the point at which the batteries are made in the first charge and discharge for the first time. Each battery is connected to the computer, each performance index of the battery is continuously monitored and recorded. 17, exhaust when battery charging, it produces gas, the gas was take out battery, until the batteries into a vacuum. 18. Seal 4 seal battery on the right side, guarantee the sealing performance of the battery. 19, remove the edge with automatic folding machine on both sides of the battery off redundant outer aluminum-plastic composite membrane, automatic folding. 20. The chemical composition of chemical composition capacity detection using high precision capacity testing equipment for battery capacity are classified. Each battery is connected to the computer, each performance index of the battery is continuously monitored and recorded. 21. Aging test battery internal resistance, voltage, appearance, capacity, size after testing qualified, classified by batch into the Treasury. Storage condition: room temperature: 10 ~ 45 ℃, humidity: 65? Aging period of 30 days. During the battery aging, should every 7 days for a regular review battery. 22. The assembly when the battery reaches the aging stage, can be assembled according to the customer's requirements ( You can use a variety of different ways to assembly) 。 When assembling, need to measure the output voltage and internal resistance of the battery. 23. According to GB/t18287 - outgoing inspection 2000 check the performance of the battery products. Must strictly according to GB/T2828 OQC. 1 sampling inspection qualified rear can leave the factory. 24. Packaging products packaging by internal double corrugated carton packaging plastic pallet and packaging, then the whole pallet and tied the belt, packaging film moisture-proof measures, to ensure the safety of the product transportation, conform to the gb191 - The provisions of the 1990 packaging storage marks.
