This partnership targets ultra-thin foil production for electric vehicle batteries, combining logistics and digital expertise to meet rising demand. With a fully customizable and efficient solution, this venture stands as a beacon in the aluminum industry's digitalization journey, promising unparalleled quality and production capabilities.


Lotte Aluminium Materials USA and SMS group have joined forces in a strategic partnership, ushering in a new era of digitalization in aluminum cathode foil production. The collaboration aims to revolutionize operations at Lotte's greenfield production site in Elizabethtown, Kentucky, USA.

At the heart of this collaboration is SMS group's advanced digitalization package, meticulously designed to orchestrate the production of ultra-thin aluminum cathode foil, catering specifically to the burgeoning demand for electric vehicle batteries. This innovative endeavor aligns with Lotte's goal of producing 36,000 metric tons of cathode foils annually, a feat made achievable through the seamless integration of SMS group's cutting-edge technologies.

The digital package encompasses a trifecta of SMS group's transformative solutions: the DataFactory Suite, the Manufacturing Execution Suite (MES), and the Quality Execution Suite (QES). This arsenal of technologies is tailored to enhance efficiency, quality, and customization throughout the manufacturing process.

The project intricately integrates six cold rolling mills, four slitting lines from a third-party supplier, and the high-bay storage system provided by AMOVA, an SMS group company. This comprehensive logistical solution ensures optimal communication between various process lines, enabling efficient logistics across the entire plant.

With a fully configurable solution, the digital package adapts to Lotte's unique production demands. It encompasses inspection procedures, production support equipment planning and administration, claim assessment, and comprehensive plant reporting at multiple operational levels. This customization ensures a harmonious fit with Lotte's existing processes worldwide.

The collaboration places a strong emphasis on quality and real-time evaluation. SMS group's MES facilitates pass-level production sequencing and intralogistics control, while the QES ensures genealogy tracking and time-length mapping from the initial pass to the final product. The integration of various third-party surface inspection systems enriches quality-related data, contributing to a comprehensive quality certification process.

This digitalization project also embraces the global aspect, allowing remote access and control possibilities from overseas. A dedicated global SMS team, coordinated by a local project management office in the US, ensures effective communication and swift issue resolution.

The long-term partnership extends beyond the project's completion, with SMS group committed to providing ongoing support through a software maintenance contract. This commitment ensures continuous operations, improvements, and the longevity of the implemented systems.

Eun Seong Chang, CEO of Lotte Aluminium Materials USA, expresses confidence in the partnership, acknowledging SMS group as the ideal partner for navigating the complexities of the aluminum industry. He emphasizes that the strategic collaboration significantly contributes to shaping the landscape of electric vehicle battery manufacturing.

Dr. Thiago Turchetti Maia, Executive Vice President CoE, SMS digital, highlights the project's predictive approach and its role in staying at the forefront of technological advancement in the aluminum industry. He underscores the commitment to reducing global carbon emissions through such forward-thinking initiatives.

This strategic partnership stands as a beacon in the aluminum foil production industry, showcasing the convergence of expertise from Lotte Aluminium Materials USA and SMS group. It promises to redefine quality, efficiency, and customization capabilities, setting new standards in the digital transformation of the aluminum sector.
