It was learned on March 11 that Zibo has added a new project for the production of 4,200 tons of carbon nanotubes per year. This project is being built by Sanrui New Materials (Zibo) Co., Ltd., and it is located in the New Materials Industrial Park of Zibo’s Xianchuang Area (east of Lushan Avenue, north of Guoli Avenue, and west of Weihu Road). The total investment in this project amounts to 350 million yuan. The project leases 20,000 square meters of factory space in the New Materials Industrial Park of the Pioneering Zone for construction; all buildings are constructed by the park itself, with Shandong Chuangke State-owned Assets Operation Co., Ltd. being the entity responsible for building them, and the project makes use of these leased facilities. The office buildings and R&D buildings are existing structures. The carbon nanotube production workshop will begin construction in August 2025, while the catalyst production and granulation packaging workshops will start construction in July 2025. The warehouses, power distribution facilities, and nitrogen production rooms will begin construction in October 2025, and the fire water tanks and pump rooms will start construction in November 2025. All of these buildings are expected to be completed by June 2026 and made available for use in this project. The project will acquire production equipment such as dissolution and stirring tanks, centrifuges, roasting furnaces, ball mills, reduction preheating furnaces, reduction furnaces, carbonization preheating furnaces, carbonization reactors, oxidation reactors, and single-walled carbon tube reactors. Once completed, the project will have the capacity to produce 200 tons of single-walled carbon nanotubes per year and 4,000 tons of multi-walled carbon nanotubes per year. Its main use is as a conductive additive for lithium batteries and sodium batteries. The catalyst and carbon nanotube production process technologies for this project are provided by Qingdao Hainar Nanotechnology Co., Ltd., and the production processes are conventional catalyst production methods as well as carbon nanotube production methods. The project duration is 42 months, with 84 employees assigned to the work. Production is carried out on a four-shift, three-shift system, resulting in 7200 hours of working time per year.
