With the Coperion extruder, the ZSW can now work on the very latest issues in the production of battery electrodes. In the current manufacturing process for this type of electrodes, the active materials are drawn in a film from a solution of the toxic NMP (N-methyl-2-pyrrolidone) onto a carrier film and then slowly dried in long ovens. In this research project the use of extruders will mean that NMP will not be needed at all in the future. Furthermore, the required drying time will also be drastically reduced and batteries with higher energy content can be produced.
