Tj. Richardson et al., FTIR SPECTROSCOPY OF METAL-OXIDE INSERTION MATERIALS - ANALYSIS OF LIXMN2O4 SPINEL ELECTRODES, Materials research bulletin, 32(5), 1997, pp. 609-618
Fourier transform infrared (FTIR) spectra were obtained from spinel-ty
pe lithium manganese oxides of composition LixMn2O4 With 0 < x < 2.4,
prepared by both chemical and electrochemical means. Each phase in thi
s system has a distinct spectrum which is characteristic of the local
(short-range) structure. Mixtures of phases were analyzed using the me
thod of scaled absorbance subtraction. The results correlate well with
previously reported XRD and neutron diffraction analyses as well as w
ith phase behavior indicated by electrochemical measurements. FTIR spe
ctroscopy thus provides both qualitative and quantitative information
and is shown to be an effective companion technique to X-ray diffracti
on. Copyright (C) 1997 Elsevier Science Ltd.
