Abstract

Li K-edge analysis obtained by scanning reflection energy loss spectroscopy (REELS) has been used to investigate the positive electrode of a Li-ion battery. Using spectral imaging data, Li mapping of a LiNi1/3Mn1/3Co1/3O2 electrode has been constructed. Inhomogeneous Li distributions are observed in LiNi1/3Mn1/3Co1/3O2 particles after cyclic electrode charging and discharging. The REELS results agree well with those obtained by scanning transmission electron microscopy-electron energy loss spectroscopy (STEM-EELS).
