Studies of Mass Transport of Components of Electrochemical Systems for Energy Storage, Conversion and Beyond using Broadband NMR Diffusion and Imaging
Abstract
Funds are provided for the acquisition of a multi-nuclear NMR system with capability to measure diffusion and other transport processes using high field gradients and micro-imaging capabilities under the DOD DURIP program. This proposal focuses on obtaining state of the art capabilities to extend this work in several substantial ways to meet emerging needs for studies of electrolytes. Our work under the current ONR contract has resulted in major improvements in performance of vanadium redox flow batteries (VRBs) licensed to a new commercial entity, coupled to studies of basic processes influencing the performance. A projected renewal will focus on extending this study to include fundamental aspects of ion and solvent transport in a number of relevant membrane/liquid electrolyte systems, requiring the use of advanced NMR methods. The proposal describes work at the intersection of NMR, electrolyte transport studies and electrochemical methods. In many cases, custom-built hardware is required for use in the NMR system. We request funds for a new multi-nuclear NMR system with capability to measure diffusion and other transport processes using high field gradients and micro-imaging capabilities to extend our capability in several ways. The electrochemical/NMR coupling takes advantage of our experience developing electrophoretic NMR for battery electrolyte studies and relies on the ability to carry out custom-builds of new cells. A number of undergraduate and graduate students will be educated in the advanced use of NMR coupled to electrochemical systems, a unique combination.
