Lithium-Ion Batteries (LIB) dominate the market for rechargeable energy storage.

The manufacturing process is highly demanding. Particularly with regard to the safety properties and the service life of the cells, it is important to drive development forward. KAMPF and its subsidiary Kampf LSF have established a joint competence team. Our experts bring in-depth know-how and many years of personal experience, both in slitting and winding technology as well as in the production of battery cells, to the joint work. This enables us to provide you with competent advice for your slitting and winding processes and to offer technically well-engineered, reliable and target-oriented solutions.

BSFWinder and BSFSlitter with integrated roll handling and automation solutions form the ideal combination for the production of the highly sensitive separator films. The slitting and winding quality of the finished products was given top priority in the development of these machines. 

In the manufacturing processes of cathodes and anodes for Lithium-Ion batteries, turret unwinders and turret rewinders of the EvoWinder type are used before and after coating lines and calender systems. This allows continuous operation without any restrictions in speed and productivity.

With the EvoSlitter, cathode and anode materials get the "right cut". Solid machine construction coupled with precise slitting systems and optional cleaning and inspection units guarantee accuracy and consistently high quality of the finished rolls.

For further slitting applications, such as for narrow strips, we also offer special, customized solutions from our slitting machine portfolio.

We would be pleased to support you personally.
