the global new energy industry is in a stage of rapid growth, and electrolyte materials, as the "blood" of lithium batteries

At present, the global new energy industry is in a stage of rapid growth, and electrolyte materials, as the "blood" of lithium batteries, are crucial for improving battery performance through technological breakthroughs. On June 29th, Fanlaite New Energy Technology Co., Ltd. made its debut with two strategic new products: semi-solid electrolyte and solid electrolyte. This is not only a significant breakthrough for Farnlet in the field of solid-state electrolyte materials for new energy batteries, but also a result of the company's increased investment in innovation and strengthened technological innovation.

This time, Farnlet released new products: semi-solid electrolyte and solid electrolyte, including semi-solid electrolyte based on in-situ polymerization and solid electrolyte based on induced decoupled ionic organics (IDIOs) and polymer ionic gel (PolyIG) routes.

At present, the market has increasingly high requirements for the energy density and safety of lithium-ion batteries. Fanlaite's research and development layout mainly focuses on the "three highs": higher energy density, higher safety, and higher technological content. The company has developed a targeted semi-solid gel electrolyte with high pressure resistance, high mechanical stability, acupuncture without fire, explosion and high quality. By selecting high-performance gel polymer monomer and initiator and combining solvent, lithium salt and functional additives, the optimal semi-solid electrolyte formula is designed. The in-situ polymerization process after liquid injection is adopted, which avoids the cumbersome problems of traditional polymer electrolyte molding process, and is compatible with the existing lithium ion battery manufacturing process, equipment and materials to the maximum extent, with the potential for rapid commercialization.

This semi-solid electrolyte has high lithium ion migration number, wide electrochemical window, good mechanical strength, can suppress lithium dendrites and prevent short circuits, reduce production safety issues such as electrode corrosion, volatilization, oxidation and combustion caused by electrolyte leakage, and further reduce the interface impedance between the electrolyte and electrode materials through secondary injection technology. The current adaptive product system includes ternary manganese doped square aluminum shell batteries, medium nickel ternary semi-solid soft pack batteries, and high nickel ternary semi-solid soft pack batteries. Lithium ion batteries using this electrolyte have high energy density, high safety, low volume expansion, low internal resistance, wide temperature range, and excellent cycling performance, which are basically on par with liquid batteries, effectively helping to continuously improve the basic capacity of the new energy industry and the modernization level of the industrial chain.

In addition, the R&D team of Farnlet also developed a solid electrolyte based on the route of induced decoupled ionic organics (IDIOs) and polymer ion gel (PolyIG). Unlike traditional inorganic and polymer based solid electrolytes, this polymer ionic gel has both flexibility and excellent ionic conductivity, as well as air stability, and has good continuous processing ability. The transfer of Li+from the carrier to effective structural Li+diffusion significantly improves the electrolyte ion conductivity. This electrolyte has excellent high voltage resistance (>5V), good rate performance, and wide temperature range characteristics, making it suitable for lithium/sodium metal battery systems, high-voltage battery systems, and extreme high temperature energy storage systems. We will accelerate the scale and commercialization process of solid-state batteries, and help the new energy industry chain accelerate the formation of new quality productivity.

Fanlaite is headquartered in Changsha and has multiple production bases, including Changsha in Hunan, Jiaozuo in Henan, Anqing in Anhui, and Liuzhou in Guangxi. Since its establishment in 2014, the company has been deeply involved in the new energy field for ten years, with a product layout of research and development, production, sales, and technical services for lithium-ion battery electrolytes, sodium ion battery electrolytes, solid-state battery materials, and core additives. It is widely used in new energy vehicles, energy storage systems, consumer electronics, and other fields. Through multi-dimensional optimization such as capacity expansion, technological innovation, market development, capital layout, and supply chain improvement, the company has established a good brand image in the market and become a leader in the field of new energy electric vehicle materials.

The official debut of these two strategic new products not only demonstrates Fanlaite's continuous innovation ability in the field of lithium battery materials, but also indicates that the new energy industry will trigger a new round of technological innovation and industrial revolution, ushering in the era of solid-state battery energy! Next, Fanlaite will continue to adhere to the concept of innovation driven development, deeply empower with high-quality development trends, actively create new quality productivity, provide customers with higher quality, performance, cost-effectiveness products, and more professional and reliable new energy battery electrolysis technology, work together with industry chain partners, share new technologies, and win a new future!
