LiFSI is currently the best choice to replace lithium hexafluorophosphate. At present, China has related top 5 LiFSI companies to deploy LiFSI.

Top 5 LiFSI companies in China

DFD

Company profile:
DFD in LiFSI companies in China  is a leader in the fluoride salt industry, and is gradually turning to new materials for lithium batteries and semiconductors. DFD is engaged in the production of fluorine chemical products starting from fluoride salts for aluminum. After the listing, it will gradually cut into new energy-related materials based on lithium hexafluorophosphate and semiconductor-related materials based on electronic-grade chemicals.

Among them, semiconductor-grade hydrofluoric acid has been certified by leading companies such as TSMC, and has become one of the main growth points of the company in the future.

DFD as one of the LiFSI companies in China, has been deeply involved in fluorine chemical industry for many years and has accumulated a lot of experience in lithium salt production. It has now become a leader in the lithium hexafluorophosphate industry. The advantages of technology and experience can lay a solid foundation for the future production of the new lithium salt LiFSI.

The company’s existing LiFSI production capacity is 1,600 tons/year, and the capacity under construction is 10,000 tons/year (3,000 tons/year for the first and second phases, and 4,000 tons/year for the third phase). It is expected to be gradually put into production in 2023. The construction of the existing production line is relatively early, and the production technology used is relatively backward. The company plans to build a new production line with new technology, and the cost advantage is significantly improved.

The company’s new production lines in the future will focus on production, and the old production lines will explore experience through technical transformation, testing, etc., so as to maintain the ability to continuously improve without affecting the production of the main production lines. In addition, the company as one of the LiFSI companies also has 200 tons of LiBOB, 100 tons of LiDFOB, 100 tons of LiBF4 production capacity, a new 10,000 tons of LiPO2F2 project, and a variety of lithium batteries additives.

Tinci

Company profile:
As one of the lithium hexafluorophosphate companies in China, Tinci in LiFSI companies originates from daily chemical products and gradually develops into lithium battery materials. At present, it has three business segments: daily chemical materials and special chemicals, lithium-ion battery materials, and silicone rubber materials, mainly lithium-ion battery materials. As a supplier of world-class brands, it is an international-flow fine chemical company and a leading electrolyte company with great influence and leading demonstration role in the industry.

By the end of 2021, as one of the LiFSI companies, the company’s total electrolyte production capacity will be about 230,000 tons, and it has become a leading enterprise in related industries in China. The company’s existing LiFSI design capacity is 6,400 tons/year, and the production capacity under construction is 70,000 tons/year. It is one of the few companies with stable shipments above the thousand-ton level.

Among the top 5 LiFSI companies in China, the company is currently the leading company in the lithium batteries electrolyte industry, with a production capacity of about 256,000 tons per year. The company owns most of the electrolyte upstream raw materials. Such as lithium salt LiPF6, LiFSI; solvent DMC, EC, etc.; various additives FEC, VC, etc. The company mainly produces liquid lithium salt and mainly uses it for its own use. The production cost is more advantageous, and it continues to improve the integration of electrolytes to consolidate its leading position.

Kaisheng New Materials

Company profile:
In the LiFSI companies, Kaisheng New Materials’ main products are thionyl chloride, aramid polymer monomer (m/terephthaloyl chloride), p-nitrobenzoyl chloride, polyether ketone ketone, chloroether, etc. The basic chemical raw materials of chlorine and sulfur were established as the starting point, and gradually extended to the intermediate thionyl chloride.

And further to the polymerized monomers of high-performance fiber aramid / terephthaloyl chloride, p-nitrobenzoyl chloride and other aromatic acid chloride products. Then there is the distinctive three-dimensional industrial chain structure of high-performance polymer material polyetherketoneketone (PEKK) and its related functional products.

Kaisheng New Materials as a company in top 5 LiFSI companies in China, the global leading company of thionyl chloride, the supply may tend to be tight in the future. The growing demand for LiFSI, coupled with the drive of the new sweetener sucralose, the future demand for thionyl chloride can reach 700,000 tons. However, since thionyl chloride is a restricted production product, it is difficult to approve new projects.

Based on existing and planned projects, the future supply-side production capacity will be about 600,000 tons/year. It is speculated that thionyl chloride will usher in an increase in prosperity, and from a long-term perspective, the trend and supply will be tight.

CAPCHEM

Company profile:
CAPCHEM in lithium ion battery electrolyte company is a leading global company specialized in electronic chemicals and functional materials. The company focuses on the R&D, production and sales of lithium battery chemicals, capacitor chemicals, organic fluorine chemicals and semiconductor chemicals, and is committed to providing customers with first-class “one-stop” products and solutions.

The main products are divided into: lithium-ion battery chemicals (including lithium-ion battery electrolytes, new lithium salts, additives and solvents), supercapacitor chemicals and primary lithium batteries chemicals.

YONTA in LiFSI companies LiFSI plans to have a production capacity of 23,000 tons. It will expand its production capacity of 67,000 tons of liquid LiFSI and 900 tons of solid LiFSI in Shaowu. It is expected to be put into production by the end of 2023. YONTA’s LiFSI production capacity will only account for 3% of the world in 2020, and it is predicted that it will jump to 15% in 2025, tied for second with CACHEM. In 2021, the company signed a 5.5-year long-term agreement with CATL.

LiFSI is one of the products in the agreement. In the future, CATL will purchase 80% of the company’s LiFSI production capacity. In terms of technology, the company mainly focuses on liquid LiFSI, which can reduce the cost of the company and the downstream at the same time compared to solid LiFSI. The future application goal is to reduce the cost of LiFSI to be comparable to lithium hexafluorophosphate, and customers can purchase them according to their needs.
