Abstract

Layered lithium molybdates of formula Li_xMo₂O₄ have been shown earlier to be promising cathode materials for secondary batteries. Nevertheless, a better understanding of the evolution of their transport properties as a function of Li composition and water intercalation is still required. This paper reviews the recent progress towards this understanding. ac and dc measurements have been used to describe the transport properties of the following compositions: Li_1.3Mo₂O₄, Li₂Mo₂O₄, Li_0.5(H₂O) _1.3Mo₂O₄. A combined analysis of the Arrhenius plots of conductivity and NMR spectra for the above samples suggests only one type of atomic site, between the MoO₂ layers, for the Li ions, in agreement with the results obtained by X-ray crystallographic studies. A similar study of the corresponding sodium phases: Na_0.5mo₂O₄, Na_0.9Mo₂O₄, Na_1.3Mo₂O₄ and Na_0.4(H₂O)_1.2 Mo₂O₄, is also presented.
