Towards Routine 7Li In Situ Solid-State NMR Studies of Electrochemical Processes in Li|LiPF6|LFP Cells

Abstract In this study, electrochemical processes in a Li|LiPF 6 |LFP cell have been explored applying advanced solid-state NMR technologies. In situ solid-state NMR allows to monitor structural changes in local environments in commercially available cell components during galvanostatic cycling. In collaboration with Dragonfly Energy, ePROBE GmbH and Bruker BioSpin GmbH & Co. KG, we have demonstrated an experimental procedure for routine application of in situ solid-state NMR for battery research. This points out the high potential of this approach for use in the energy storage industry.
