BRUCKMÜHL, Germany — Drying and surface processing specialist adphos Thermal Processing GmbH (ATP) has developed a new drying solution for anode and cathode water-based and solvent-based coatings.
According to ATP, aNIR-Battery Electrode Processing allows a complete electrode coating drying 10 times faster and with only a fraction of drying power, down to 10% of the present standard convection-based drying solutions. Based on the company’s advanced NIR (aNIR)-platform technology, with the propriety aNIR-Battery Electrode Processing, an electrode coating up to 150 µm thickness can be dried in ≤ 2 s and only requires a coating thickness up to 400 µm ≤ 5 s. ATP stated that with currently experienced limitations at accelerated drying rates — especially observed with infrared and laser-based heating/drying systems — are not given with aNIR-Battery Electrode Processing, due to avoidance of cracking or resulting binder migration induced low coatings adhesion to the electrode substrates.
