However, the storage mechanism and local interactions appearing during this reaction still needs further clarification. 1 H, 13 C and 23 Na ex situ solid\u2010state NMR (ss\u2010NMR) experiments are performed to obtain insights into the storage mechanism depending on the state of charge (SOC) and the electrolyte solvent used. Distinct differences could be seen depending on the SOC, indicating a possible change of the solvation shell, differences in the mobility as well as a phase transition at the voltage plateau. Furthermore, exchange experiments reveal information on the sodium ion transport process in the graphitic lattice. The inferior cycling performance of triglyme (3G) (compared to diglyme (2G) and pentaglyme (5G)) is also reflected in the ss\u2010NMR spectra, showing a reduced mobility and stronger interactions between sodium ions, 3G and graphite already at room temperature (RT).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>DOI: 10.1002\/batt.202200421 Authors: Ines Escher, Annica I.
