Breaking the lithium storage limit via independent bilayer units within 2D layer materials

摘要

cqvip:Lithium intercalation into graphite contributes a theoretical capacity of 372 m Ah g-1and thus leads to an earthshaking change for energy storage[1].Lithium intercalation behaviors have been investigated via X-ray diffraction(XRD),Raman,Fourier transform infrared spectroscopy(FTIR)and X-ray absorption fine structure (XAFS)with the aid of in-situ electrochemical characterization technologies.
