Tailoring a Desired Interphase

As described above, computation approaches were usually employed to estimate the reduction or the oxidation potentials of candidate molecules, which are related to 

Other oxygen-containing compounds may also be present in the SEI. The O Is spectrum of the anode cycled containing STD with 2 % DMDO electrolyte is slightly different from that of the anode containing STD electrolyte. In addition to the C-O and C=0 peaks observed with the STD electrolyte, a new peak at -534.3 eV is 

Based on the computation results we concluded that DMDO preferably reduced on the anode surface forming linear polymer as opposed to cyclic polymer  

While the formation of DMDO-based species on cathode is not clear yet, the authors believed that the migration of the rednction products of DMDO on graphite anode snrface to cathode side might be the possible reason. 

Besides the above-described polymerizable monomer additives, snlfnr-based componnds were proposed in our group as additives for forming anode SEI, inclnding butyl sultone (BS) [82, 83], propane sultone (PS) [84, 85], prop-l-ene-l,3-sulton (PES) [86], as well as ES [54,87], These sulfur family additives have higher reduction potentials than the electrolyte solvents, as shown in Fig. 5.29.
