Benefiting from the development of the lithium battery industry, the market demand for N-methylpyrrolidone has increased

NMP (N-methylpyrrolidone) is the solvent of PVDF binder. It is a colorless and transparent liquid with the characteristics of low toxicity, low viscosity, high boiling point, excellent chemical stability and thermal stability. It is widely used in lithium batteries In preparation. NMP is mainly used in lithium batteries, polymer materials, petroleum and petrochemicals, insulation materials, electronic materials and other fields. Among them, the lithium battery field accounts for 75%, followed by the polymer materials field, accounting for 15%.

The raw materials of NMP are mainly BDO (1,4-butanediol), butyrolactone, methylamine, etc. BDO accounts for about 50% of the cost of NMP. In the past five years, BDO production has continued to rise, from 1.25 million tons in 2017 to 1.77 million tons in 2021. The higher output of BDO is conducive to the development of the NMP industry.

Driven by the development of the high-energy-density lithium battery industry, shipments of carbon nanotube conductive slurries continue to rise, reaching 80,000 tons in 2021 and expected to reach 330,000 tons by 2025. Benefiting from the development of the new energy industry, my country’s lithium-ion battery shipments continue to rise, from 82GWh in 2017 to 325GWh in 2021.

According to the “2022-2026 NMP Industry In-depth Market Research and Investment Strategy Suggestions Report” released by the Industrial Research Center, the lithium battery industry development, driving the demand for NMP to continue to rise. In 2021, the scale of NMP used in lithium batteries in my country will reach 340,000 tons, and it is expected to be about 880,000 tons in 2025. As the demand for NMP applications rises, its market size continues to rise, from 4 billion yuan in 2021 to 26.5 billion yuan in 2025.

Overseas companies have been early deployed in the NMP field. They have high product quality, strong technology research and development capabilities, and have competitive advantages in the market, such as BASF of Germany, Mitsubishi of Japan, Ashland of the United States, and Maichi Chemical. As my country’s NMP production technology becomes increasingly mature and products are improved, overseas companies gradually withdraw from the domestic market, and my country’s NMP becomes localized.

NMP manufacturers in my country include Shandong Qingyun Changxin Chemical Technology Co., Ltd., Binzhou Yuneng Chemical Co., Ltd., Xuchang Ruida Biotechnology Co., Ltd., Puyang Guangming Chemical Co., Ltd., Nanjing Jinlong Chemical Plant, Sichuan Lutianhua, and Shengli Oilfield East Shengxingrun Chemical Co., Ltd., China Salt Anhui Red Sifang Co., Ltd., Zhejiang Liansheng Chemical Industry Co., Ltd., etc., have a total domestic production capacity of about 160,000 tons. Although my country’s NMP has been domestically produced, its products are mainly concentrated in the mid- to low-end fields, its production technology is weak, and its product quality levels are uneven.

Industry analysts said that NMP is mainly used in the field of lithium batteries. Benefiting from the development of my country’s new energy industry in recent years, NMP applications Demand continues to rise, and the industry has good development prospects. In terms of production, there are many NMP manufacturers in my country. At present, overseas companies are mainly concentrated in high-end fields and have strong market competitiveness. my country’s NMP is mainly concentrated in low-end fields, and their share in the domestic market is also increasing.
