Prior information notice without call for competition: Miscellaneous special-purpose machinery Description of the procurement: Coated foils emerge from the production lines, which are first cut and then wound up. Vacuum drying technology removes the remaining solvent and gases from the electrode coils. Drying takes place in a vacuum to lower the process temperature and protect the battery materials. The coated anode and cathode foils should be processed separately from one another under clean and dry room conditions. The number of ovens required depends on their storage capacity and the amount of coils that will be produced in different production scenarios. Between 2 and 4 coils per oven should be dried at the same time, for which appropriate inserts must be provided. To implement three-shift operation in electrode production, a modular construction of the vacuum ovens should be provided, in which several heating chambers should share the periphery (e.g. vacuum systems, control cabinet). Space-saving solutions regarding the relocation of the peripheral devices to another floor or the embedding of the stoves in the walls of the clean or dry room are desirable. A typical drying process takes place at approx. 130 o C and takes approx. 8 to 24 hours. The ovens should be able to reach a maximum temperature of 200 oC . Exhaust air containing NMP should be processed by the plant process in such a way that it poses no danger to the environment. After the vacuum drying is complete, the coils are either packaged and stored or transferred directly to the next step, cell assembly in the drying room.
