dc.description.abstract | Lithiated transition metal oxides such as LiNiVO4, Li2MnO3 and Li0.4WO3 used as cathode materials in high density lithium-ion batteries, show intense optical absorption followed by fluorescence in the region of 2-4 eV. These optical transitions can tentatively be assigned to either transition metal to oxygen charge transfer type or Jahn-Teller type local distortion. For fluorescing samples (LiNiVO4, Li2MnO3 and Li0.4WO4), photo-induced impedance (Bode plot) data show significant enhancement in impedance under low frequency range (∼10 Hz). However, more important cathode materials such as LiCoO2 and LiMn2O4 do not show either fluorescence or photo-induced impedance enhancement. The presence or absence of an optical transition in the cathode system may give some clues on the tendency for electrochemical fading. © 2002 Elsevier Science B.V. All rights reserved. | - |
