Battery foil / separator foil

Cutting battery foil or separator foil for various applications is a demanding process. Battery foil is a high-tech product that consists of various layers of different materials for coated anode- cathode material. These require a very precise treatment and cutting method. Therefore, the right cutting technology is imperative.

DIENES Know-How

Thanks to more than 100 years experience industrial cutting tools from DIENES you will excel in quality and economy. In this context, the avoidance or minimization of metallic blade abrasion and cutting dust reduction are further material-specific challenges that DIENES meets.
We have developed suitable materials for knife pairings and the associated knife holders to cut critical films, such as battery film and separator film. Here, the technical design of the knife is particularly important, in that the appropriate cutting angles, surface finish, and flatness and parallelism must be considered.
Our goal is the reproducible generation of defined cutting edges. To this end, DIENES offers all the necessary components for the various cutting processes, such as roll shear cut, razor blade cut and shear cut: the right knife in different material qualities, special sleeves as well as adequate bottom knives and knife holders.
