From: Fluorine-oxygen co-coordination of lithium in fluorinated polymers for broad temperature quasi-solid-state batteries

Fig. 3

Molecular dynamic simulation snapshots of (a) non-fluorinated quasi-solid polymer electrolyte, and (b) fluorinated quasi-solid polymer electrolyte. Radical distribution functions and the corresponding average coordination numbers for the poly-BA (c) and poly-HFA (d) quasi-solid polymer electrolytes. e MSD of Li+ in poly-BA and poly-HFA quasi-solid polymer electrolytes. f Oxygen K-edge XANES spectra of fluorinated quasi-solid polymer electrolyte and non-fluorinated quasi-solid polymer electrolyte. The normalization method is to subtract the background signal, set the pre-edge to 0, and set the post-edge at the end to 1. g 7Li ssNMR spectra of non-fluorinated quasi-solid polymer electrolyte and fluorinated quasi-solid polymer electrolyte. h 19F ssNMR spectra of fluorinated quasi-solid polymer electrolyte with or without LiFSI.
