The cathode electrolyte interphase (CEI) will be usually formed spontaneously in the charge/discharge process at the high voltage. However, the stability and electrochemical property is not satisfactory to protect the cathode.[16], [17] To yield efficient protection layer of high-voltage cathodes, ...
cathode electrolyte interphase (CEI) layer formed in the concentrated electrolyte is a uniform and robust LiF-rich CEI, which is a sharp contrast with the uneven and fragile organic-rich CEI formed in the dilute electrolyte. The LiF-rich CEI not only effectively inhibits the dissolution of TMs ...
This improvement can be ascribed to the suppression ofelectrolyte decomposition and transition metal ion dissolution by TMSPi, due to the preferentialoxidation of TMSPi to electrolyte and the formation of a protective solid electrolyte interphase on LiNi1/3Co1/3Mn1/3O2, which are confirmed by ...
By forming a cathode electrolyte interphase (CEI) through electrochemical oxidation of tris(trimethylsilyl) borate (TMSB), we successfully stabilized LiCoO2 in water-in-salt electrolyte at a high cut-off voltage that corresponds to 0.7e electron charge transfer. To the best of our knowledge, this ...
Here, we propose a strategy, for the first time, to form an artificial Li+-conducting cathode-electrolyte interphase (ALCEI) on the NCM811 cathode surface using a nucleophilic reaction between polysulfides and vinylene carbonate (VC). The as-formed ALCEI layer simultaneously protects the NCM ...
