What is NMP solvent？
NMP, is one of the most commonly used lithium battery auxiliary materials. NMP is the solvent of PVDF binder, is N-methyl pyrrolidine ketone, a colorless transparent liquid, with low toxicity, high boiling point, strong polarity, low viscosity, strong dissolution ability, chemical stability, excellent thermal stability, and water, PVDF, cathode, 리튬 이온 배터리 음극 materials, widely used in the preparation of lithium batteries.
When making the electrode tablet, NMP solvent integrates the binder, cathode active substance, conductive agent and other electrodes together, so that the binder is in full contact with other substances and evenly distributed. NMP solvent, its quality directly affects the quality of lithium ion battery paste coating, is an indispensable solvent material. From the distribution of NMP solvent application field, it is mainly used in the preparation of lithium batteries, accounting for 74%.
Application of NMP solvent in lithium batteries
Surry preparation: NMP solvent, as the solvent of binder polyvinylidene fluoride (PVDF), mi, solves, stirs and distributes binder, conductive agent and cathode active substance to form uniform slurry. The quality of slurry dispersion directly affects the quality and performance of lithium ion battery.
Coating: it is the next process after the preparation of the slurry. The paste with good stability, high viscosity and good fluidity is evenly coated on the cathode metal foil. NMP solvent, as the liquid carrier of the paste, has very good wettability and fluidity, and is the mainstream coating solvent. The coating link is of great significance to the capacity, service life and safety of lithium-ion batteries.
Drying: After coating, the cathode sheet is baked and dried in the vacuum dryer. The baking temperature is 120 ± 5 degrees Celsius, and the NMP solvent in the electrode slurry is removed, so that the adhesive, conductive agent and cathode material in the slurry form a porous film with uniform pore size and uniform distribution, and cover the electrode sheet.
NMP solvents for other applications
Polymer industry, NMP solvent as a solvent for polyreaction.
Insulation material industry, NMP solvent in the insulation material industry for polyimide paint reaction and dilution solvent.
In the electronic materials industry, NMP solvent is used for the integrated circuit, LED, PCB, semiconductor cleaning of electronic materials, mainly ultra-pure electronic chemicals.

NMP solvent production capacity in China
BDO performs dehydrogenation in the presence of a metal oxide catalyst to produce GBL, and GBL reacts with monomethylamine (MMA) to form NMP. By December 2021, there are 13 GBL production enterprises made from BDO raw materials, with a total production capacity of 485,000 tons or under construction, and the actual total output in 2020 is 180,000 tons. The production capacity of NMP solvent can be divided into synthesis and recycling and purification.
정화: By the first half of 2021, the whole NMP solvent industry in China and the waste NMP solvent recovery and purification processing capacity is more than 1.55 million tons.
Synthesis: There are 11 NMP solvent production enterprises in China from GBL, with a total production capacity of 281,000 tons and an actual total production capacity of 150,000 tons in 2020.
Among them, NMP solvent synthesis is mainly concentrated in Shandong, Henan and Shaanxi, recycling and purification is mainly concentrated in Jiangsu, Anhui and Jiangxi, and other scattered in Chongqing, Zhuhai, Hangzhou and so on. PVDF price rise, driving NMP solvent price rising
According to reports, from January to May 2021, the cumulative output of new energy vehicles in China was 1.02 million, up 262% year on year; and the cumulative power battery production from January to May was 59.5GWh, up 227% year on year.
Benefiting from the rapid development of the new energy vehicle industry, the supply gap of PVDF has been widening since the fourth quarter of 2020, and the product price is also rising. In July 2021, the average price of lithium battery products has increased from about 70,000 RMB in 2020 to more than 170,000.
As a necessary supporting solvent for PVDF, the price of NMP solvent has also been rising along with PVDF, from 15,000 RMB / ton at the beginning of 2021 to more than 40,000 RMB / ton at present.
Market size calculation of NMP solvent
Lithium battery demand outbreak is expected to drive the rapid growth of NMP solvent market. Assuming that lithium iron phosphate and 삼원계 리튬 배터리 cathode materials maintain a 1 to 1 utilization rate, it is calculated that an average of 573Wh of lithium battery per kg of active material can be produced.
Assuming that the energy density will grow at a rate of 5% in the future, and the market size of lithium batteries in China is calculated, the demand scale of 음극 재료 in the next five years is estimated, and then the NMP usage will be measured by the average 50% solid content of the industry.
It is forecast to grow rapidly to 879,000 tons by 2025. In terms of unit price, assuming that the price of NMP solvent remains at 30,000 / ton in the future, the market size of NMP solvent in China will grow to 26.4 billion RMB in 2025, CAGR46.6% in the next five years

NMP solvent industry competition pattern
In terms of the competitive pattern, with the increasing maturity of Chinese manufacturers’ technology and the improvement of product quality, the advantages of competitors from other countries, such as BASF, Mitsubishi Chemical and other products, no longer exist, and gradually withdraw from the Chinese market.
At present, China’s competition is mainly the competition between direct manufacturers, recycling and purification manufacturers and a small number of import and export traders. Recycling and purification manufacturers occupy the scattered customer base and low-end market, while direct manufacturers occupy the main customer base and high-end market.
At present, the NMP industry competition group is roughly divided into two categories: the first competition group is competitive enterprises, such as Germany, Japan mitsubishi, ash, Michael chemical, this kind of enterprise is generally larger market enterprises, long time, technology research and development ability, they have capital and channels and so on various advantages, strong competitiveness.
The second competitive group is small and medium-sized NMP enterprises, which have a large number and small scale, with little brand influence, general technology, and uneven quality of NMP products.
The world’s representative NMP solvent manufacturers mainly include BASF, Germany, Ashland, Mitsubishi Chemical, Japan. China’s representative NMP production enterprises are Binzhou Yuneng, Maiqi Chemical, Changxin Chemical, Anhui Shengjie Energy and so on.
