APPLICATION OF NEUTRON METROLOGY METHODS TO ELECTROCHEMICAL ENERGY SYSTEMS
RECIPIENT: General Motors, LLC, Honeoye Falls, NY
Metrology methods based on neutron beam attenuation are well-suited to diagnostic applications in a variety of practical electrochemical energy systems. This project will apply neutron detectors with spatial resolution as fine as 10 micrometers to resolve water gradients normal to the membrane electrode assembly (MEA) in fuel cells, a 10-fold improvement in resolution over prior efforts. This project will also apply neutron detectors to study lithium transport in batteries to assess mechanisms for degradation of battery capacity and power. Development of new metrology methods and applications for interrogation of water in fuel cells and lithium in batteries will enable improved performance, durability, and cost of these key electrochemical energy technologies.
