From: Dynamic gel as artificial interphase layer for ultrahigh-rate and large-capacity lithium metal anode
a The chemical stability of CS/DF-PEG-DF film in different electrolytes. b 1H SSNMR spectra and (c) FTIR spectra of CS/DF-PEG-DF and CS/DF-PEG-DF/Li. d Cross-section SEM image and (e) AFM image of CS/DF-PEG-DF@Li formed by adding 50 μL CS/DF-PEG-DF/DMSO solution. f Linear sweep voltammetry (LSV) curves of Li||PEG or CS/DF-PEG-DF||stainless steel (SS) batteries. g Photographs of the bare Li and CS/DF-PEG-DF@Li anode exposed in ambient air for different minutes.
