Primetals Technologies has secured a new contract from Chinese manufacturer Lidao New Energy to supply seven Technology Control System (TCS) packages for an aluminium foil mill project at the company’s production facility in Wuhe, Bengbu City, Anhui Province.

The project will strengthen Lidao’s production capacity for battery aluminium foil, a critical material used in lithium-ion batteries for electric vehicles, energy storage systems and other new energy applications. The seven foil mills are scheduled to be commissioned progressively through 2027.

A key feature of the project is the deployment of Primetals Technologies’ latest Integrated Solenoid Valve Electric (ISV-E) and Integrated Solenoid Valve Electric Compact (ISV-EC) systems, marking an important technological milestone for the company. The fully electric spray bar systems are designed to provide highly accurate flatness control during the rolling process, helping manufacturers produce the ultra-thin, high-quality foil required for modern battery applications.

The scope of supply also includes ABSM flatness rolls and associated TCS systems for all seven mills. Using optimised three-dimensional spray patterns, the ISV-EC technology delivers precise roll cooling and improved strip flatness, meeting the demanding quality standards of battery foil production.

Designed and assembled in the United Kingdom, the ISV spray bars are supported by Primetals Technologies’ complete range of engineering services, including design, manufacturing, installation, commissioning and after-sales support.

The latest contract further expands the long-standing partnership between Primetals Technologies and Lidao New Energy. In 2022, Lidao ordered eight TCS packages, Air Bearing ShapeMeters and the original ISV spray bar systems.
