Opening up a new market segment - rewinders for electrodes

In everyday life, which is increasingly characterized by electromobility, the development of new, associated market segments for companies is not only a sign of growth, but also of adaptability and forward thinking. In a current project, SOMATEC has shown that its in-house winding machines can also be used for coated electrode foils, demonstrating the value of such machines for this growth market.

Electromobility has experienced an unprecedented boom in recent years. At the heart of this upswing is the need to produce high-quality batteries efficiently and reliably. Coated copper foils are used as electrodes for this purpose, and it is particularly important that they are wound without wrinkles. Coated electrode foils are at the heart of battery production in electric vehicles. This is where SOMATEC comes into play as an international manufacturer of winding machines.

The challenges of winding copper foil

The handling of copper foils, especially their winding, poses a particular challenge due to their thinness and sensitivity. Wrinkling and material damage are common problems that make the foil unusable for the end product, resulting in a high level of waste. SOMATEC's technological expertise makes it possible to overcome these challenges. Our ATW-E turret winder can wind the thin copper foils without wrinkles or folds, which leads to a significant increase in quality and efficiency in production. Thanks to precise control and handling when changing reels, the TAC feed system also ensures that the foils are undamaged and prepared for further processing in the highest quality.

The ATW turret winder with TAC feed system

The ATW turret winder is a prime example of SOMATEC's innovative strength. Originally developed for paper and film production, this winder is characterized by its modular design and high adaptability. The turret winder can be extended with various handling components and is available in several sizes to adapt to any production environment. The advantages include sizes to suit requirements, stable processes thanks to automatic reel change and an optional clean room design. This flexibility makes it ideal for the demanding requirements of electrode winding in the e-mobility industry.
