Xi'an Taijin New Energy and Materials Sci-Tech Co., Ltd.
About
Xi'an Taijin New Energy and Materials Sci-Tech Co., Ltd. (TJNE), listed on the Shanghai Stock Exchange STAR Market (688813.SH), manufactures titanium electrode materials and electrochemical equipment for water treatment, electrolytic copper foil production, and cathodic protection. Controlled by the Northwest Institute for Non-ferrous Metal Research and founded in 2000, the company operates over 68,000 square meters of production facilities and holds more than 206 patents across 29 core technologies. The water treatment portfolio centers on titanium anodes for electrochlorination systems generating sodium hypochlorite via seawater or brine electrolysis, available from 50 g/h to 5,000 g/h chlorine production capacity with Ru-Ir coatings for applications including drinking water disinfection, ballast water treatment, and circulating water descaling. Ozone electrolysis anodes using SnO2-coated titanium produce 1–4.5 ppm aqueous ozone for advanced oxidation of micropollutants, bacteria, and pesticide residues. Specialized anodes address ammonia nitrogen removal and industrial wastewater electrochemical oxidation. For cathodic protection, MMO anode plates with Ru-Ir coatings deliver service lives exceeding 20 years in seawater and soil environments. TJNE is also the leading domestic producer of complete electrolytic copper foil equipment and the earliest Chinese company with mature mass-produced titanium-based lead dioxide (PbO2) anodes. Manufacturing spans four factories covering titanium electrode materials, copper foil equipment, PbO2 anode surface treatment, and hydrogen production electrolysis systems.
