Figure 13. Compatible electrolyte design with anode: Silicon/Graphite. (A) Schematic illustration for the incorporation of DMVC-OCF3 and DMVC-OTMS in the VC scaffold leads to the creation of a flexible and robust solid electrolyte interphase (SEI) on the Si-C anode. (B) Tendency of the Young’s modulus of the Si nanolayer of the Si-C anode during cycling of NCM811/Si-C full cells. Reproduced with permission^[109]. Copyright 2021, Springer Nature. Li metal. (C) Schematic illustration of anion-enrichment interface and anion-derived interphases. (D) Schematic illustration of anion-rich solvation structure and anion-derived interphase (left) and conventional solvation structure and solvent-derived interphase (right). (E) Electrode thickness and porosity of deposited Li calculated from focused ion beam-scanning electron microscopy (FIB-SEM) results. Inset are cross-section SEM images of Li metal deposited on Cu at the current density of 0.5 mA cm^-2 for 10 h. Scale bar: 10 μm. (F) Digital images of Li deposited on Cu foil and corresponding separators in 1M LiBF₄ + 1M LiDFOB tFEP/FEC (left) and 1M LiPF₆ EC/DMC (right). (G) XPS spectra of B 1s and F 1s for LMA in 1 M LiBF₄ + 1 M LiDFOB tFEP/FEC electrolyte. (H) SEM images of cross-sectioned NMC811 cathodes cycled in 1 M LiBF₄ + 1 M LiDFOB tFEP/FEC (top) and 1 M LiPF₆/EC-DMC (bottom) electrolytes. Reproduced with permission^[110].
