Investigating the effect of a fluoroethylene carbonate additive on lithium deposition and the solid electrolyte interphase in lithium metal batteries using in situ NMR spectroscopy

An in situ NMR study of Li deposition and the SEI on Li metal. Isotope exchange measurements reveal the fast transport properties in the SEI formed with FEC and the accelerated SEI formation rate, in part explaining the homogeneous electrodeposition using FEC additives.
