ALD NanoSolutions and the University of Colorado awarded a US Patent for Deposition of Thin Films onto Li-Ion Battery Electrodes

DENVER, CO (Nov. 24, 2015) – Extending its proprietary Particle ALDTM and Polymer ALD™ technology platform, ALD NanoSolutions (ALDN) has exclusively licensed technology from the University of Colorado to develop novel  battery  electrode coatings.  The newly issued US Patent Number 9,196,901 “Lithium Battery Electrodes with Ultra-Thin Alumina Coatings” covers a process to create proprietary films which provide critical physical and chemical properties for extending the lifetime of lithium ion batteries.

Using atomic layer deposition, the innovation allows for alumina coatings to penetrate into the electrode and conformally coat the active electrode particles. This precision surface coating builds physical strength as well as providing chemical protection in the lithium battery electrodes to mitigate degradation.  Both these enhancements increase the lifetime of conventional batteries, as well as enable cell manufacturers to extend the operating temperature and voltage range of future batteries. From a manufacturing scaling perspective, this patent also proposes a “drop in” ALD reactor solution to the current electrode manufacturing process.
