N-methylpyrrolidone (NMP) downstream industry situation

NMP products are mainly used in new energy sources such as lithium-ion batteries and power batteries, and new material industries such as aramid, polyphenylene sulfide,NMP supplier and polyimide. With the rapid development of my country's emerging industries into pillar industries, the consumption of new energy and new materials in downstream industries has increased sharply. Coupled with the introduction of technology and self-improvement in downstream industries, the downstream industry chain has grown rapidly to meet the needs of national economic and social development.

Lithium-ion battery industry

As one of the main raw materials in the lithium-ion battery manufacturing process, NMP directly affects the coating quality and environmental protection requirements of lithium-ion batteries. According to industry survey data analysis,nmp although differences in models and specifications will lead to different proportions of NMP in the value of lithium-ion batteries, overall, NMP accounts for about 3%-6% of the manufacturing cost of lithium-ion batteries. The market size of NMP And demand is also growing with the growth of lithium-ion batteries, especially energy storage batteries and power batteries.

Lithium-ion battery technology has certain outstanding advantages such as high energy density, long cycle life, small self-discharge rate, no memory effect, and green and environmental protection.lithium from battery It is currently the most ideal secondary battery in my country. Lithium-ion batteries are widely used in the design of portable electronic information products, such as notebook computers, mobile phones, and digital cameras. With the development of the new energy industry, lithium-ion battery systems have gradually become the main power battery for electric tools, electric bicycles and electric vehicles due to their unique high specific energy and high specific power characteristics. In addition, lithium-ion batteries also have some important applications in the field of energy storage.

Polymer materials industry

NMP is also a necessary solvent for chemical reactions and dilution in the production of aramid, poly-p-phenylene sulfide and polyimide polymers, directly affecting the smooth completion of low-temperature polycondensation reactions and raw material product transportation. Aramid fiber is a new type of high-tech synthetic fiber with excellent properties such as ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance, and light weight. Its strength is 5-6 times that of steel wire, and its modulus is that of steel wire or glass fiber. 2-3 times that of steel wire, its toughness is 2 times that of steel wire, its weight is only about 1/5 of steel wire, and it does not melt. It has good insulation properties and anti-aging properties, and has a long life. The discovery of aramid is considered a very important historical process in the field of materials.
