In situ construction of a favorable cathode electrolyte interphase through a fluorosilane additive for high-performance Li-rich cathode materials
文献摘要：
Li-rich manganese-based oxides(LRMO)with high capacities are attractive cathode materials for next-gener-ation lithium-ion batteries.However,poor cycling stability is one of the key issues impeding their commercialization.Here,for the first time,we employed trimethoxy(3,3,3-trifluoropropyl)silane(TMTFS)as a multifunctional elec-trolyte additive to stabilize the LRMO cathode interphase and elevate its cycling performance.The LRMO electrode delivered a high reversible capacity of 250.4 mAh-g-1 with a stable capacity retention of 91％after 200 cycles.Detailed analysis using in situ powder X-ray diffraction(PXRD),cyclic voltammetry(CV),nuclear magnetic res-onance(NMR),X-ray photoelectron energy spectra(XPS)and transmission electron microscopy(TEM)demon-strated that the TMTFS additive can not only form a robust,thin,and dense LiF-dominated cathode electrolyte interphase,but also scavenge detrimental HF in elec-trolyte.Additionally,the TMTFS additive can adjust the solvation environment,thus enhancing the transference number of lithium ions.
