Logic of electrolyte industry: integrated layout is the general trend. The raw material cost of electrolyte accounts for a very high proportion, and the cost barrier and technical barrier of the industry are based on solute, solvent and additive. Therefore, the integrated layout is the inevitable choice to build the competitiveness of the industry. Logic of integrated layout: the vertical industrial chain layout can not only ensure the stable supply of raw materials, but also have a significant cost reduction effect, so as to improve the profitability of enterprises. Taking Guangzhou Tinci Materials Technology Co.Ltd(002709) as an example, under the condition of realizing the complete self-sufficiency of solvents and additives, the gross profit margin of electrolyte business is 14 PCT higher than that of complete outsourcing. At the same time, it will expand the layout of lithium fluoride, pyroxene and other fluorinated materials in the field of lithium fluoride and lithium fluoride, and expand the cost of lithium fluoride, pyroxene and other fluorinated materials in the upstream.
As the mainstream electrolyte, lithium hexafluorophosphate has a tight balance between supply and demand, and the shipment of new lithium salt lithium difluorosulfonate imide has increased rapidly
At present, the mainstream electrolyte solute is lithium hexafluorophosphate. Due to its long production capacity construction cycle, the lithium hexafluorophosphate industry is in a tight balance in the short term, and the prices of lithium hexafluorophosphate and electrolyte continue to rise. Due to its better hydrolysis resistance, thermal stability, chemical stability and high and low temperature performance than lithium hexafluorophosphate, lithium difluorosulfimide has attracted extensive attention in the market. In view of its high cost, it is mainly used as an additive. It is expected that with the improvement of technology and the reduction of cost, the penetration rate of lifsi will increase rapidly, and has become the layout focus of major enterprises in the electrolyte industry.
The purification of solvent has significant technical barriers, which is the key link to reflect the technical ability of electrolyte enterprises, and the enterprise competitiveness of mastering the industry know-how is prominent
Solvent accounts for the highest mass proportion in the electrolyte of lithium battery At present, the mainstream electrolyte solvents in the market are DMC and EMC. Solvent purification is the key link of preparation and one of the main technical barriers. Enterprises that master the industry know-how have stronger competitiveness and voice. The leading enterprises in the industry Guangzhou Tinci Materials Technology Co.Ltd(002709) , Shenzhen Capchem Technology.Ltd(300037) , Jiangsu Guotai International Group Co.Ltd(002091) are all laying out in the solvent link and developing new solvents at the same time.
Additives have customized properties and are the key link to reflect the differentiation of electrolyte. Mastering diversified additive formulas will help to meet various needs of customers and enhance the competitiveness of the industry
The quality of additives in electrolyte is relatively low and has the characteristics of customization Different additives are mainly configured according to the specific needs of downstream battery manufacturers It is the key link to reflect the differentiation of electrolyte. Electrolyte additives can significantly improve the energy density, cycle performance, rate performance, high and low temperature performance and safety of the battery Under the trend of high nickel in lithium batteries, the demand for additives is further increased. At present, the mainstream additives in the market include ethylene carbonate, fluoroethylene carbonate and so on.
