A battery cell for in situ NMR measurements of liquid electrolytes
This work describes the development of an in situ battery cell to monitor liquid electrolytes by means of NMR spectroscopy. The suitability of this approach is confirmed by NMR measurements and electrochemical analysis. The cell allows for undistorted high resolution NMR spectroscopy. Furthermore, constant current cycling data, C-rate sequences and impedance measurements indicates a long cycle life as well as reasonable specific capacities and Ohmic resistances.
