  • The important process standards of lithium-ion battery PACK
    July 09, 2021 The important process standards of lithium-ion battery PACK
    Lithium-ion battery PACK is divided into four parts: processing, assembly, testing, and packaging. The battery PACK must be screened before. Different customers have completely different requirements for the cells before the lithium-ion battery PACK. Many manufacturers have a lot of battery PACK factories. Strict requirements, let’s take a look at the important process standards of lithium-ion battery PACK today. In the lithium-ion battery pack industry, people call batteries that are not assembled and can be directly used individually as batteries, and the finished battery pack connected to the PCM board with charging and discharging functions is called lithium-ion battery PACK. The PACK process of lithium-ion batteries refers to the assembly of battery cells, protective plates, battery wires, battery nickel sheets, battery accessories, battery boxes, battery membranes, etc. into finished batteries by welding. The battery pack PACK requires the battery to have a high degree of consistency (capacity, internal resistance, voltage, discharge curve, life). The vast majority of the existing lithium-ion battery PACK technology is to link the cells together by welding, which also complicates the maintenance of battery problems. In addition, the batteries may face many thorny problems when they are batched. Reliability of batch products, excellent battery PACK technology, and finished product testing are essential. 1. Full inspection standard of battery cell appearance The appearance standard of cylindrical batteries: no short circuit, oxidation, rust, leakage of veneer pad or skewed surface pad, film breakage, film wrinkle, etc. The appearance standard of the square battery cell: no electrolyte, burr or other contaminants on the surface, no leakage, bulging, deformation, short circuit, etc., no skew or warping of the surface pad, no oxidation, dirt, desoldering, etc. on the composite nickel belt. The appearance standard of polymer batteries: no electrolyte or other pollution on the surface, no leakage, swelling, deformation, etc., no fracture of the tab, no damage to the corners, no delamination, etc. 2. Standard for battery cell veneer pad The surface pad is required to be firmly pasted, not skewed, warped, not beyond the edge of the end face of the battery, and not cover the negative rivet---aluminum shell battery positive cap (for multiple parallel strings, use formed barley paper or red steel paper to paste)-- -For steel shell cylindrical batteries; covered with textured paper or high-temperature adhesive paper---polymer batteries. 3. Cell voltage and internal resistance test Test equipment: multimeter, multi-function test stand, battery internal resistance tester, general battery test stand, scanner. Test connection method: The positive and negative terminals of the battery are contacted with the positive and negative thimble of the test frame respectively. 4. Battery cell combination standard Cylindrical battery: Adhesive bonding process, using g...

  • Power lithium battery anode : aluminum foil application potential is huge
    July 07, 2021 Power lithium battery anode : aluminum foil application potential is huge
    The power battery for electric vehicles is a lithium battery: the positive electrode is lithium iron phosphate (lithium cobalt oxide LiCoO2, or lithium manganese oxide LiMn2O4 or ternary compound Li(NiCo)O2) coated on aluminum foil, but lithium iron phosphate is the best . The negative electrode is copper foil coated with graphite or lithium titanate. There is a separator between the positive and negative foils, which are wound together. Put the wound positive and negative sheets (including the diaphragm) into the battery case together, inject the electrolyte, and then vacuum package to complete the production of a single battery. The procurement cost of lithium battery cathode materials accounted for 30%, anode materials accounted for 20%, separator materials accounted for 20%, electrolyte accounted for 20%, and casing accounted for 10%. The diaphragm is polyacrylic acid. The positive electrode material has a great influence on the battery performance (referring to the lithium compound coated on the aluminum foil), and the entire positive electrode is the most critical part of the battery. The development of the new energy automobile industry is not only related to national energy security, people's livelihood and environmental protection, but also involves the destiny of my country's automobile industry. The positive electrode of the lithium battery of electric vehicles needs aluminum foil, and the weight of the vehicle itself is required to be as light as possible. Aluminum is the preferred material for lightweighting of automotive parts. Aluminum plays a vital role in the development of electric vehicles and hybrid vehicles. It is predicted that China's electric vehicle ownership will account for more than 30% of the total in 2030. China's new energy automobile industry has opened up a new application field for the application of aluminum, with great potential and considerable consumption. The anode aluminum foil for lithium batteries has no special requirements on the performance of the aluminum foil, and the Chinese aluminum foil industry can fully meet all the requirements for this kind of foil.
