Figure 3. H-transfer reaction from (A) SL/SL (-H), (B) FB/FB (-H) and (C) EC/EC(-2H) to the delithiated NCM811 (003) cathode surface from periodic DFT calculations. Typical HR-TEM images of cycled NCM811 electrodes recovered from MCMB||NCM811 full-cells after 50 cycles with (D) BE, (E) LiDFOB-LiBF4/SL and (F) LiDFOB-LiBF4/SL-FB. (G) XPS F 1s, O 1s, S 2p and B 1s spectra for NCM811 cathodes recovered form MCMB||NCM811 full cells after 50 cycles with various electrolytes.
