What is the electrolyte of lithium battery? What are the manufacturers and companies of lithium battery electrolyte in China? Lithium battery materials are mainly composed of five major parts: positive pole, negative pole, electrolyte, diaphragm and shell. As the medium of lithium ion transmission in the battery, the electrolyte of lithium battery should not only have high lithium ion conductivity, but also have excellent electronic insulation when connecting the positive and negative electrodes of the battery. Today, we summarized some lithium battery electrolyte manufacturers for your reference.

What is the electrolyte of lithium battery?

Lithium battery electrolyte is the carrier of ion transport in the battery, which is generally composed of lithium salt and organic solvent. The electrolyte plays the role of conducting ions between the positive and negative electrodes of the lithium battery, which guarantees the lithium battery to obtain high voltage, high specific energy and other advantages. Electrolyte plays an important role in the performance of lithium battery (such as capacity density, cycle performance, rate performance, storage performance, etc.). Electrolyte is generally made of high-purity organic solvent, solute, necessary functional additives and other raw materials in a certain proportion under certain conditions.

Lithium battery electrolyte manufacturers and companies:

After the survey of electrolyte enterprises, we ranked the top six lithium battery electrolytes according to the output of the enterprises, hoping to be of benefit to you.

Inventory of lithium battery electrolyte company:

1. Shenzhen New Zebang Technology Co., Ltd

Time of establishment: 2002 Headquarters: Shenzhen

The main business products of New Zebang include lithium battery chemicals, capacitor chemicals, organic fluorine chemicals and semiconductor chemicals, of which the revenue of lithium battery chemicals in the first half of 2016 was 347 million yuan.

At present, the lithium battery electrolyte capacity of New Zebang is 20000 tons/year, with two factories in Huizhou and Nantong. In the near future, we have begun to lay out new lithium salt additives, jointly invested with Xinlian Huayuan to establish Hunan Bofu Technology, and built a LiFSI project with an annual output of 200 tons, which is expected to reach the end of 2016. The strong R&D strength and high-quality customer structure are the main reasons why New Zebang has occupied the leading position in recent years. New Zebang has a high-quality R&D team, and has acquired Zhangjiagang Hankang, an additive enterprise, and Haisifu, a fluorine chemical enterprise, with obvious synergistic effects. New Zebang's customers cover both domestic and foreign markets, mainly mainstream enterprises, such as Samsung SDI, Sony, BYD, Zhuguangyu, LG, etc.

2. Guangzhou Tianci High tech Materials Co., Ltd

Time of establishment: 1996 Headquarters: Guangzhou

Guangzhou Tianci's main businesses include lithium ion battery materials, personal care materials and silicone rubber materials, of which the revenue of lithium battery materials in the first half of 2016 was 525 million yuan (including Kaixin).

Guangzhou Tianci currently has an electrolyte capacity of 23000 tons/year (excluding Kaixin), with two production bases in Guangzhou and Jiujiang; Tianci produces and sells its own lithium hexafluorophosphate, with a production capacity of 2000 tons/year at present. It is expected to build a 6000 ton/year liquid lithium hexafluorophosphate production line (equivalent to 2000 tons/year of crystalline lithium hexafluorophosphate) by the end of this year, and a 2000 ton/year crystalline lithium hexafluorophosphate production capacity will be built in 2017. By then, a 6000 ton/year crystalline lithium hexafluorophosphate production capacity will be formed; Another 300 t/a LiFSI project is expected to reach production capacity by the end of this year.

At the end of 2015, Tianci participated in Jiangsu Ronghui and set foot in the upstream raw material lithium carbonate; In 2016, Tianci Materials made two capital increases in Jiangxi Aide Nano, currently owning 51% of its shares, and has arranged lithium iron phosphate cathode materials. Different from New Zebang's focus on electrolyte, Guangzhou Tianci has actively laid out upstream materials. At present, it has achieved self-sufficiency in core raw materials, lithium hexafluorophosphate, and actively laid out lithium iron phosphate and its upstream materials, lithium carbonate and iron phosphate, to improve the layout of cathode materials and electrolyte industry chain.

In the first half of 2016, against the background of the soaring price of lithium hexafluorophosphate, Tianci produced lithium hexafluorophosphate by itself, which had obvious cost advantages. Its gross margin of electrolyte reached 46.16%, 9 percentage points higher than that of New Zebang. It is expected that the price of lithium hexafluorophosphate will remain at a high level in the second half of this year, and its high gross profit will continue to be maintained.

3. Zhangjiagang Guotai Huarong Chemical New Materials Co., Ltd

Time of establishment: 2000 Headquarters: Zhangjiagang

Cathay Huarong is a holding subsidiary of Jiangsu Cathay Pacific. At present, its main products include lithium battery electrolyte and silane coupling agent. In the first half of 2016, the company's overall revenue was 441 million yuan.

At present, the company's electrolyte capacity is 10000 tons/year. In the near future, it plans to invest 150 million to implement the 20000 tons/year power battery electrolyte expansion project. After the project reaches its capacity, a total capacity of 30000 tons/year will be formed. The company is currently laying out LiTFSI, and plans to expand the original 30t/a production line to 200t/a.

In 2014, Cathay Pacific Huarong and its parent company, Jiangsu Cathay Pacific, invested in Guangzhou Libao with 8.75 million yuan respectively, accounting for 12.5% of the equity respectively, and distributed in the field of ternary materials. Cathay Pacific Huarong has been a leading enterprise in the domestic electrolyte industry before 2014. After 2014, its layout in electrolyte is relatively small, and it has been surpassed by New Zebang, Tianci and other listed companies. This year, through investment to expand production and layout of ternary materials, the future competitive strength is expected to improve.

4. Dongguan Kaixin Battery Materials Co., Ltd

Time of establishment: 2012 Headquarters: Dongguan

Dongguan Kaixin was wholly acquired by Guangzhou Tianci in 2014. At present, its main product is lithium battery electrolyte. The Company's Dongguan base has a capacity of 10000 tons/year, and its Ningde plant's 10000 tons/year production line is expected to reach the end of this year, when it will have a capacity of 20000 tons/year.

After being acquired by Tianci, Dongguan Kaixin can give full play to its overall marketing and resource advantages through more detailed market coverage division plan and customer sharing. The main customers of Kaixin are CATL and ATL, while the other customers are mainly Powerful God and Bike. As the future production expansion plan of CATL is gradually reached, its sales volume will gradually increase.

5. Tianjin Jinniu Power Materials Co., Ltd

Time of establishment: 2001 Headquarters: Tianjin

Tianjin Jinniu was jointly established by Xingtai Mining (Group) Co., Ltd. and CNOOC Tianjin Chemical Research and Design Institute. Its main product is lithium electrolyte, similar to Tianci, and its lithium hexafluorophosphate is produced and sold by itself.

At present, the company's electrolyte capacity is 10000 tons/year, and the actual capacity of lithium hexafluorophosphate is 800 tons/year. The company is expanding its production capacity.

At present, Tianjin Jinniu's main customers are Powerful God, Samsung SDI, Guoxuan Hi Tech, Sony, etc. In 2015, the company increased the technology and market layout of power type electrolyte, and in 2016, the proportion of power type electrolyte gradually increased, reaching about 50%. Restricted by the background of state-owned enterprises, the approval process for Jinniu's investment and expansion is complicated and the progress is slow, which limits its sales growth. After its production capacity is released, the sales level will be further improved.

6. Dongguan Shanshan Battery Materials Co., Ltd

Time of establishment: 2005 Headquarters: Dongguan

Dongguan Shanshan is a subsidiary of Shanshan Co., Ltd. (600884. SZ), whose main business is lithium battery electrolyte. At present, the company has two production bases, Dongguan and Langfang. The capacity of Dongguan factory is 10000 tons/year, and the capacity of Langfang factory is 5000 tons/year. In the first half of 2016, the company realized an operating income of 187 million yuan, up 156.26% year on year.

In the first half of 2016, the sales volume and selling price of electrolyte of the company increased significantly, turning losses into profits. Previously, except ATL (including CATL), the customers of Dongguan Shanshan were mainly small and medium-sized digital customers. This year, through the adjustment of customer structure and the establishment of an innovation team, some substantial progress was made in matching electrolytes with new materials such as lithium titanate and silicon carbon cathode, which improved the overall competitiveness of the company.

Development trend of lithium battery electrolyte industry:

1. Since the core technology of lithium battery electrolyte products lies in additives, the current global electrolyte giants such as Mitsubishi Chemical, Ube, Samsung SDI, etc. have their own unique additive technologies, which can be sold by purchasing raw materials and then processing and modifying them properly. Therefore, the development trend of electrolyte industry in the future will gradually show that enterprises master core technology, reduce enterprise costs and improve production efficiency through outsourcing processing.

2. Improving voltage and stability is the future development direction. In the field of small lithium batteries, high energy density is emphasized. For electrolyte, improving the working voltage to meet the requirements of higher energy density is the future development direction.

3. Lithium batteries are widely used, and different technical routes and lithium batteries in different application fields have different requirements for electrolyte. Therefore, electrolyte manufacturers need to cooperate with downstream customers to develop, thus forming a more stable cooperative relationship. It can be said that each improvement of lithium battery performance is inseparable from the progress of electrolyte.

Analysis on the price trend of lithium battery electrolyte:

The electrolyte accounts for 5-15% of the cost of lithium battery, and the gross profit margin of the product is 25-30%. Lithium salt of electrolyte is mainly lithium hexafluorophosphate, accounting for 40% of the cost of electrolyte. According to the information learned from the industry, it is generally expected that the price of electrolyte will continue to decline in the next two years, with 36000 yuan/ton as the general expectation. We estimate that the gross profit of 10000 tons, the net profit of 3000-5000 tons, and the investment amount of 5000 tons of equipment are about 100 million yuan. The total investment return can reach 15% - 25%.

Because the prices of lithium electrolyte with different functions vary greatly, but on the overall trend, the average price of electrolyte in 2013 was about 48000 yuan to 50000 yuan, a decrease of about 25% compared with 2012, while the average market price in the fourth quarter of 2013 has dropped to about 40000 yuan/ton.

After years of development, domestic lithium battery electrolyte has become the most technologically mature variety among the four major materials. At present, it has been exported in large quantities, accounting for more than 50% of the global share. With the explosive growth of demand for electric vehicles, electric bicycles and lithium batteries for energy storage, the demand for lithium batteries will continue to grow rapidly in the future, and the market potential for lithium battery electrolyte is huge. Xiaobian is optimistic that we will continue to be optimistic about China's lithium battery electrolyte industry.

These are six manufacturers and companies that have done well in lithium battery electrolyte. Only those enterprises with technological and supply advantages can keep up with the development of large lithium battery electrolyte plants, and then gain a larger market share in the fierce market competition.
