Acheson Introduces Ultra-Flexible Coating for Lithium Ion Batteries

PORT HURON, MI, November 22, 2006 - Acheson has introduced Dag® EB-012, a versatile conductive, protective coating for lithium-ion and lithium-ion polymer batteries. In addition, Dag EB-012 can be used as a current collector primer coating for electric double layer capacitor (EDLC) applications and as a conductive coating on screw threads. Dag EB-012 is a single-component, water-based dispersion of graphite in a thermoplastic binder that provides an extremely flexible coating with low resistance at low cure temperature. With proper dilution, Dag EB-012 can be applied by spray, brush, roll or print methods. Once cured, Dag EB-012 provides a tenacious chemical- and solvent-resistant coating for most metal substrates. The water-based, low-VOC coating enables easier environmental compliance, while its low-temperature cure provides energy savings and reduced process costs. Dag EB-012 delivers excellent adhesion to copper and aluminum substrates for lithium-ion and polymer lithium-ion battery applications, providing excellent adhesion of electrode materials to the current collector for stable conductivity and chemical and solvent resistance. The product can be applied wet by spray, bush, roller or flexo and gravure print techniques for processing flexibility.
