Lithium iron phosphate batteries differ from other lithium batteries only in positive electrode materials, and the process is similar to that of other lithium batteries. The main processes are: ingredients-coating-rolling-slitting-filming-winding-assembly-laser welding-baking-liquid injection-activation-forming-sealing-cleaning-dividing-sorting. The main difference is that lithium and iron phosphate materials have poor electrical conductivity, so the particles of the material are relatively fine and the specific surface area is large, making it difficult to disperse the ingredients and making it easier to disperse. water absorption. The other differences really aren't that big.
Propylene oxide is the original material for manufacturing lithium batteries. Among the manufacturing materials for lithium batteries, there are products based on propylene oxide. Wecan be said that the quality of propylene oxide will have a certain impact on the manufacturing of lithium batteries. Therefore, the industry should strengthen the management of propylene oxide to prevent poor management of propylene oxide from hindering the manufacturing of lithium batteries. At the same time, because propylene oxide is a toxic and corrosive solid, workers should be careful when using it to avoid direct contact and bodily harm.
1. Propylene Oxide
Propylene oxide, also known as propylene oxide and ethylene oxide methyl ester, is a very important raw material for organic compounds, just behind polypropylene and acrylonitrile. the third largest derivative of propylene. Propylene oxide is a colorless ether liquid with a low boiling point and is flammable. Propylene oxide is partially miscible with water and miscible with ethanol et to ether. Forms a binary azeotrope with pentane, pentene, cyclopentane, cyclopentane and dichloromethane. Toxic and irritant to mucous membranes and skin, can damage the cornea and conjunctiva, cause respiratory pain, burns and swelling of the skin, or even tissue necrosis.
2. Lithium battery
Lithium battery is a primary battery that uses lithium metal or lithium alloy as the positive electrode material and non-aqueous electrolyte as the electrolyte. It is different from the rechargeable battery. lithium ion batteries and lithium ion polymer batteries. Since the chemical properties of lithium metal are very active, the processing, storage and use of lithium metal are subject to very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of microelectronic technology inAt the end of the 20th century, the number of miniaturized devices increased day by day, placing high demands on power supplies. At this point, lithium batteries have entered the stage of large-scale practical use.
In summary, at this stage, there is a high demand for lithium batteries in society. In other words, there is a high demand for propylene oxide in society. Workers must fully understand the properties of propylene oxide and take appropriate protection before carrying out corresponding operations. Avoid physical damage to workers caused by propylene oxide during operation.
