Provision of anode material for cutting tests

Situation und Motivation

The Sovema Group's Solith business unit develops equipment for both laboratory-scale pilot lines and medium to large-scale automated production facilities. To further strengthen its competitive position, Sovema Group (Solith) is looking at expanding its product range for lithium-ion battery cell assembly. Sovema (Solith) is expanding its product range with a highly productive electrode foil-cutting system.

 

Approach

  1. Material procurement by Fraunhofer FFB
  2. Production of the anode material: mixed slurry for the anode and subsequent coating of the copper foil
  3. Coating with commercially available anode formulation consisting of Graphite, conductive carbon black, CMC (carboxymethyl cellulose), and SBR (styrene butadiene rubber).
  4. Packaging of the coil in foil and delivery

Results

The customer received detailed information on the process of anode material production. In this context, the recipe for the anode material was carefully selected, and the procurement and preparation of the required materials were initiated. In the further course, the production of the anode material took place, which was then appropriately packaged for delivery to the Sovema Group. There, the anode material will be used to advance the development of a cutting system for electrode foils, in particular by using an innovative cutting process to increase productivity.
