Fraunhofer researchers develop new low-cost dry-film electrode production process

Green Car Congress

BroadBit uses it to produce new types of sodium-ion batteries. In order to protect operators and the environment, elaborate precautions for occupational safety and reprocessing are necessary. On a laboratory scale, the IWS can already coat electrode foil with a remarkable production speed of several meters per minute.
