Who are top 5 lithium hexafluorophosphate manufacturers in China

Lithium hexafluorophosphate, white crystal or powder, has good ion migration number and dissociation constant, high electrical conductivity and electrochemical stability, good oxidation resistance and aluminum foil passivation ability, and can match with various cathode and anode materials. It is currently the most widely used commercial lithium battery electrolyte, accounting for more than 50% of the cost of the electrolyte.

Since 2021, driven by the explosive growth in demand for new energy electric vehicles and lithium battery, the price of lithium hexafluorophosphate has been rising all the way.

Companies have seized opportunities for new energy development to expand production, and the production capacity of lithium hexafluorophosphate has also doubled. This article sorts out the top 5 lithium hexafluorophosphate manufacturers in China including Tinci, DFD, TONZE, STA and YONTA.

1. Top 5 lithium hexafluorophosphate manufacturers in China list

① Tinci

Tinci's main business is lithium battery materials and daily chemical and specialty chemical materials. Tinci is one of the top 10 lithium battery electrolyte companies in China. It has laid out core raw materials for electrolytes such as lithium hexafluorophosphate, lithium bisfluorosulfonimide, and solvents, forming an integrated industrial chain.

Tinci's lithium hexafluorophosphate is mainly in liquid state, and is mainly produced directly by organic solvent method, which is convenient for supporting enterprises to produce their own electrolyte and can significantly reduce production costs.

As of the end of 2022, Tinci has about 62,000 tons/year lithium hexafluorophosphate production capacity (consolidated), and there are many lithium hexafluorophosphate projects under construction and proposed.

② DFD

DFD independently developed high-purity crystalline lithium hexafluorophosphate by using industrial-grade lithium carbonate, anhydrous hydrogen fluoride, and phosphorus trichloride, and is the world's largest crystalline lithium hexafluorophosphate manufacturer.

By the end of 2022, the production capacity of polyfluorine and polycrystalline lithium hexafluorophosphate would reach 55,000 tons per year. The 2022 annual report previously released by DFD shows that in 2023, DFD's lithium hexafluorophosphate capacity under construction will be 40,000 tons per year.

The projects under construction include the ultra-clean and high-purity crystal lithium hexafluorophosphate project with an annual output of 30,000 tons, and the second-phase project with an annual output of 20,000 tons of high-purity crystal lithium hexafluorophosphate and additives.

③ TONZE

TONZE's main business is lithium hexafluorophosphate and small household appliances.

By the end of 2022, Xintai materials, a wholly-owned subsidiary of TONZE, has an annual production capacity of 8,160 tons of lithium hexafluorophosphate, and Taiji Material, a holding subsidiary, has an annual production capacity of 10,000 tons of lithium hexafluorophosphate.

④ STA

STA is a manufacturer of aluminum alloys and aluminum electrolytic materials. Its main products include aluminum master alloy series, new energy-saving materials potassium fluoroaluminate, lithium hexafluorophosphate, aluminum grain refiner, etc.

In 2021, STA actively deploys lithium hexafluorophosphate, a raw material for new energy lithium batteries, and invests in a subsidiary to build a production line project with an annual output of 15,000 tons of hexafluorophosphate.

In November 2021, the first demonstration production line with an annual output of 800 tons of lithium hexafluorophosphate has been put into operation and realized sales. In August 2022, the second phase of the production line with an annual output of 3,000 tons has been commissioned and put into operation, and the third and fourth phase projects are in progress.

⑤ YONTA

YONTA is a manufacturer of fluorine-containing pharmaceuticals, pesticides and new energy materials. Among them, lithium battery materials include lithium hexafluorophosphate, lithium bisfluorosulfonyl imide, VC, FEC, etc.

By the end of 2022, YONTA has a lithium hexafluorophosphate production capacity of 8,000 tons per year. On June 15, 2021, YONTA announced that it plans to invest in an industrialization project with an annual output of 20,000 tons of lithium hexafluorophosphate, 1,200 tons of related additives and 50,000 tons of hydrofluoric acid.

Later, YONTA adjusted the project and turned it into a liquid lithium salt industrialization project with an annual output of 134,000 tons. Including an annual output of 67,000 tons of lithium hexafluorophosphate solution and 67,000 tons of lithium bisfluorosulfonimide solution, construction has started in December 2021.

2. Conclusion

In addition to these top 5 lithium hexafluorophosphate manufacturers in China, there are a lot of other professional lithium hexafluorophosphate manufacturers in China. The choice of which lithium hexafluorophosphate manufacturer depends on the needed applications and the manufacturer product. Every manufacturer product has its strengths, weaknesses, and richer experience in some areas than others.
