Jiangtong Copper Foil is a high-tech state-owned holding enterprise integrating the research and development, production and sales of electrolytic copper foil. In June 2003, it was jointly established by Jiangxi Copper Industry Group Co., Ltd. and Yez Copper Foil Co., Ltd.; in March 2022, the company's shareholding transformation was completed and renamed Jiangxi Jiangxi Copper Foil Technology Co., Ltd. The existing annual production capacity of various electrolytic copper foils is 30,000 tons, including 15,000 tons of copper foil for conventional electronic circuits and 15,000 tons of electrolytic copper foil for lithium batteries. In 2023, 32,195 tons of copper foil were sold, including 19,141 tons of electronic circuit copper foil and 13,054 tons of lithium battery copper foil, setting a record high and achieving operating income of 2.5 billion yuan.

In 2022, the company was recognized as a "specialized, specialized and new" small and medium-sized enterprise in Jiangxi Province and won the title of "Science and Technology Reform Enterprise" of the State-owned Assets Supervision and Administration Commission of the State Council in 2022. In 2023, it was recognized as a benchmark enterprise in Jiangxi Province's intelligent manufacturing and a specialized small giant enterprise in Jiangxi Province.

In terms of scientific and technological innovation: the "Jiangxi Province Electrolytic Copper Foil Green Technology Development and Application Engineering Research Center" and the "Nanchang High-frequency High-speed Electrolytic Copper Foil Engineering Center" were established, and on this basis, a research and development center was established and a 26 people's independent R&D team. Among them, the "R&D and Industrial Application of 5G High-Strength Low-Profile Electronic Copper Foil Manufacturing Complete Set" cooperated with Jiangxi University of Science and Technology won the first prize of the Jiangxi Science and Technology Progress Award.

In terms of capacity scale: There are currently two projects under construction. One is located in Shangrao Economic and Technological Development Zone. The total production capacity of electrolytic copper foil for lithium batteries is 100,000 tons/year. The project is completed in two phases. The production scale of the first phase of the project is 50,000 tons/year. The first phase has been basically completed and the project is in the final stage. The second is the fourth phase project, with a designed production capacity of 20,000 tons/year copper foil for high-end electronic circuits. At present, all civil engineering projects have been completed and the project construction has been basically completed. By then, if all production capacity is released, it will reach a scale of 100,000 tons.
