Interface stabilization of 1,1,2,2-tetrafluoroethyl-2,2,3,3-tetrafluoropropyl ether to high-voltage Li-rich Mn-based layered cathode materials

Non-aqueous electrolyte solvents play a pivotal role in improving the cycling performance of high-voltage Li-rich Mn-based layered cathode materials. In this study, a fluoroether (1,1,2,2-tetrafluoroethyl-2,2,3,3-tetrafluoropropyl ether, TFEPE) was added to 1.2 mol·L^(-1)LiPF_(6)EC/EMC/DEC at different concentrations to synthesize a series of electrolytes for enhancing the cycling performance of highvoltage Li_(1.18)Mn_(0.50)Ni_(0.26)Co_(0.06)O_(2)(LMNC).
