Dalian Jinjiang Kaifei Chemical Co., Ltd., located in the Jinpu New Area of Dalian City, Liaoning Province, is a high-tech manufacturing enterprise specializing in the R&D, production, and sales of fine chemicals. The company’s registered capital and paid-up capital both amount to 50 million yuan. Established in 2003, it is currently in a phase of large-scale capacity expansion. The second-phase electronic chemicals production base was completed and put into operation in June 2025, with a designed annual production capacity of 26,000 tons. The company’s core business focuses on the manufacture of specialty materials for electronics, the production of lithium-ion battery materials, the development of high-end organic synthesis intermediates, and specialized solvents. Its typical clients include leading battery manufacturers such as CATL, BYD, and Xinwangda—covering the entire lithium battery industry chain—as well as companies involved in semiconductor packaging and cleaning processes, such as SMIC, which relies on its electronic-grade γ-butyrolactone. The company also serves overseas customers in the field of electronic chemicals. Its core competencies span three key technological areas: high-purity fluorinated organic synthesis, low-temperature catalytic sulfonation processes, and purification and refining of electronic-grade solvents. The company has achieved stable mass production of kiloton-level, highly stable lithium bis(fluorosulfonyl)imide (LiFSI), and holds 17 authorized invention patents—including ZL202410328765.2—and 9 utility model patents. All these patents are clearly owned and remain valid. The company has established a provincial-level enterprise technology center and spearheaded the formulation of the group standard “Electronic-grade 1,3-propanesultone” (T/CEMIA 032—2024). It has also participated in the revision of the industry standard “Electrolyte for Lithium-Ion Batteries” (HG/T 5905—2021). The company holds ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018 certifications, and possesses the “Safety Production License,” the “National Industrial Product Production License” (for hazardous chemical organic products), and the “Pollutant Emission Permit.” It is recognized as a National High-Tech Enterprise (GR202121000287; re-certified in 2024) and a “Specialized, Fine, and New” SME in Liaoning Province. Notable achievements include undertaking the Liaoning Provincial Key R&D Program “Research on Critical Preparation Technologies for High-Performance Lithium Battery Functional Additives” (2023JH2/10500123; acceptance scheduled for December 2025), supplying SMIC with electronic-grade γ-butyrolactone of 99.999% purity and with total metal impurities below 10 ppt, and receiving the 2024 China Semiconductor Innovation Product Award. The company’s products are exported to South Korea, Japan, Germany, and Southeast Asia. In 2025, its export value reached 128 million yuan. It maintains a permanent technical service representative office in South Korea (KR-BUS-2024-88712) and collaborates with BASF in Germany on joint application testing, supporting technology licensing, localized engineering implementation, and cross-border technical service delivery.
