14.3 Billion Yuan! Progress Report on Sichuan Copper Mine Lithium Battery Copper Foil Project

According to “Nanxi Media,” in the Longlong Industrial Park within Naxi Economic Development Zone, Yibin City, Sichuan, Sichuan Copper Mine Technology Co., Ltd. has fully resumed work and production for its annual 20,000-ton high-performance lithium battery copper foil project.

“The project is expected to complete the main structure by the end of May this year, with equipment debugging and production testing in the second half of the year. Once fully operational, the annual output value can reach 2 billion yuan, injecting new vitality into the local power battery industry,” said Liang Mingqiang, deputy manager of the Sichuan Copper Mine Lithium Battery Copper Foil Project.

It is understood that the Sichuan Copper Mine lithium battery copper foil project has a total investment of 1.43 billion yuan. It is a core supporting project in the power battery industry chain in Naxi District and a key investment attraction project in Yibin City. The project mainly produces ultra-thin high-performance lithium battery copper foil, which fully meets the high endurance, fast charging, and high safety requirements of next-generation power batteries. It is a core anode current collector for power batteries, energy storage systems, and solid-state batteries. (Source: Battery Hundred People’s Conference - Battery Network)

Targeting New Materials! Hengtong Copper Foil Phase II Accelerates Construction

According to “Deyang Daily,” Hengtong Precision Copper Foil Technology (Deyang) Co., Ltd. (referred to as Hengtong Copper Foil) is accelerating pile foundation work at its Phase II construction site, laying a solid foundation for subsequent phases.

“Currently, we are fully pushing forward with pile driving, planning to drive 726 piles. We have completed 371 so far, with over half the progress,” said Zhang Weiqiang, vice general manager of the company. The project will build 31,000 square meters of factory space and install 12 new production lines, creating a high-end composite foil transformation base mainly producing composite copper-aluminum foil and other products.

“Our products from Phase II can be widely applied in circuit boards, solid-state batteries, solar panels, and more, with broad prospects,” Zhang Weiqiang said. Unlike Phase I, which produces traditional copper foil, Phase II targets the “new track” in the field of new materials, with higher technical content and added value.
