Fig. 4

Scanning electron microscopy (SEM) images of the cycled NCM-811 cathode harvested from the NCM-811//Li half-cell assembled with a, b a typical liquid electrolyte (after 50 cycles) and e, f an MOF-based quasi-solid electrolyte (after 300 cycles). Argon-etching Fourier transform infrared spectrum (FT-IR) of the cycled NCM-811 cathode within c a typical liquid electrolyte (after 50 cycles) and g an MOF-based quasi-liquid electrolyte (after 300 cycles). Etching FT-IR spectra and the corresponding color mappings of the cycled NCM-811 cathode using the d typical liquid electrolyte and h MOF-based quasi-solid electrolyte.
