Fig.2 Schematic of the effect of FEC additives on a Li metal anode(A) [ 63], the calculated total coordination number for Li + in LiPF6 in EC with 0, 5%, 10% FEC(B), the representative solvation structures taken from molecular dynamics(MD) simulation snapshots of 1 mol/L LiPF6 in EC(C) and 1 mol/L LiPF6 in EC with 10% FEC(D) [ 64], snapshots of the MD simulation boxes of LiFSI/LiNO3 and LiFSI electrolyte(top panel), schematics of the solvation structure of Li ions in corresponding electrolyte(bottom panel)(E) [ 65] and schematic illustration of the EDL principle in screening reactants to preferentially construct the SEI(F) [ 60]
