Overview
Personal Profile
Andrew Colclasure leads NLR's materials development and modeling research efforts within the Electrochemical Energy Storage group. His work includes advances in electrochemical modeling and experimentation for fast charging, next-generation silicon anodes, battery recycling, solid-state electrolytes, eliminating the use of critical materials, and physics-based machine learning. Colclasure is developing novel, safe, long-life batteries for stationary energy storage to enable greater penetration of renewable energy sources. Before joining NLR, Colclasure was a staff scientist at ITN Energy Systems, working to rapidly commercialize solid-state lithium batteries, lithium-air batteries, and vanadium redox flow batteries.
