Recently, Rolechem leveraging the technical advantages and leading market position of its core product, Lithium Bis(fluorosulfonyl)imide (LiFSI), was successfully awarded the title of "2025 Shanghai Manufacturing Single Champion Enterprise." This accolade cements its position as a benchmark enterprise in the field of high-end lithium battery electrolyte materials, serving as an authoritative recognition of Rolechem's deep cultivation and technological innovation capabilities in this specialized sector.

As a national-level "Little Giant" enterprise with professional, refined, unique, and innovative characteristics, Rolechem has been deeply dedicated to the specialized track of novel electrolytes and additives since its establishment in 2016, building a solid technical barrier centered around LiFSI. As a core electrolyte lithium salt for lithium-ion batteries, LiFSI possesses overall technical performance superior to traditional lithium hexafluorophosphate ($LiPF_6$): its thermal stability is significantly enhanced, with a decomposition temperature exceeding 200°C, effectively eliminating safety hazards caused by the decomposition of electrolyte lithium salts in high-temperature environments. Furthermore, it boasts high ionic conductivity, performing outstandingly in both room-temperature and low-temperature environments—its conductivity at -20°C remains superior to that of traditional lithium salts, ensuring normal battery operation across a wide temperature range.

This material also exhibits strong hydrolysis resistance, effectively preventing the degradation of electrical performance caused by trace amounts of water. Concurrently, it can form a dense and stable SEI (Solid Electrolyte Interphase) film on the surface of electrode active materials, inhibiting the growth of lithium dendrites and drastically improving battery cycle life and rate capability. In addition, its excellent electrochemical stability makes it highly compatible with battery systems such as mid-nickel and lithium iron phosphate (LFP) batteries. Whether utilized as an additive or a main salt, it can significantly enhance battery rate performance and energy storage efficiency. It serves as a critical适配 material for power and energy storage batteries, while also possessing significant potential for future solid-state battery R&D, becoming a pivotal material bridging the current lithium battery industry with next-generation technologies.

On the market side, relying on its first-mover technical advantage, Rolechem has secured a globally leading market position. The company is one of the pioneer enterprises in China to achieve large-scale mass production of LiFSI, with a product purity reaching over 99.99% and a production efficiency exceeding the industry average, firmly maintaining its place among the top ranks in global market share. Thanks to its stable quality and performance, the company's products have been supplied in batches to leading domestic and international power and energy storage battery manufacturers, and are exported to more than 20 countries and regions including Europe, the Americas, Japan, and South Korea. This establishes Rolechem as a core supplier in the global lithium battery industrial chain, significantly driving the independent and controllable level of China's advanced lithium battery materials. By the end of 2025, the company accumulated a total of 108 related patents and led or participated in the formulation of multiple industry standards, continuously expanding its technical voice and market influence.

Rolechem plans to add 20,000 tons of liquid LiFSI capacity in 2026. Relying on the comprehensive supporting infrastructure of its Jining production base in Shandong, the company aims to achieve rapid commissioning and delivery. This capacity expansion will effectively satisfy the soaring global demand for LiFSI, provide stable localized supply chain support for downstream enterprises, and enhance the synergistic efficiency of the industrial chain.

Looking ahead, Rolechem will continuously focus on the technical iteration and application expansion of LiFSI, optimizing production processes, reducing costs, and increasing R&D investment in derivative materials for solid-state batteries to consistently maintain its dual leadership in technology and the market. Meanwhile, the company will give full play to its leading role as a manufacturing single champion, actively responding to Shanghai's advanced manufacturing development strategy. By driving collaborative innovation among upstream and downstream enterprises, Rolechem aims to inject strong momentum into the high-quality development of China's new energy industry and the enhancement of the global competitiveness of "Made in Shanghai."
