Another adphos instantaneous drying solution for battery production lines

adphos Group, Bruckmühl, Germany, is a family of privately owned companies focused on the development of adphosNIR® technology which dramatically reduces the time and space required for thermal processes and provides quantum leaps forward in efficiencies.

Again, a leading Asian battery company (undisclosed) has selected adphos Digital Printing GmbH proprietary aNIR® -drying solution for its new processing lines, the company said in a press release. This time the drying of barrier coatings for battery separators on temperature sensitive polymer films will be realized in the new production lines with aNIR®-driers. The aNIR®-driers enable here drying processes in a fraction of a second, compared of today required 5 to even 10 s with convection dryer-based solutions.

With a dryer space requirement of only 10 % of the conventional dryer sizes, now even very compact and low-tension vertical coating lines can be realized with the aNIR®-systems. In addition, thanks to the fully electro-thermal aNIR®-technology, energy saving of up to 80 % and no CO2 emissions, has to be addressed. Furthermore, the application for the drying of water as well as solvent-based coatings is possible and already realized. Therefore for battery electrode coatings, either as integrated and booster aNIR®-solutions or completely stand-alone with the proprietary BearLITE®-process are given. The resulting battery products provide greater power, higher energy density and performance compared to traditional dried battery electrodes. Even dynamic heat assisted NIR-processing in electrode calendering processing is successfully proven.
