(16) Saueressig GmbH & Co. KG

saueressig_logo_180x258px2The Saueressig GmbH + Co. KG has brought a new technology for the compression of dry powder materials and lithium ion battery electrodes on to the market. This technique increases the efficiency of batteries and capacitors production because active materials can be prepared without wet coating and subsequent drying through the processing of so-called dry films. In addition, solvent-based additives are not necessary for this production process. Innovative approaches are involved since this process depends on special conditions: highest line pressures, lowest web tension and smallest thickness tolerances in the final product. With their patented gap control, Saueressig units achieve product thickness tolerances in the micrometer range. The electrode tapes and dry films, which are compressed at this time, are essential for the design and performance of lithium ion batteries and capacitors.
As a technical architect for process and application development including the implementation of industrialized methods for individual customer processes, the in-house manufacturing and extensive know-how of Saueressig is very impressive.
