Abstract
The non-stoichiometric Mo18O52 oxide, based on the MoO3 structure, was tested as a cathode material in both primary and secondary Li cells. It may intercalate reversibly in its layered structure up to 1.2 Li/Mo (at 0.5–1.0 mA cm−2), so forming ternary phases. In the solid matrix Li+ ion diffusion is relatively fast (D≈10−9 cm2 s−1) and gives rise to a structure in which Li+ is tetrahedrally coordinated by oxygen. This oxide shows a high rate capability and can also act as a cathode material for secondary batteries in the low-rate range. The resemblance to the parent oxide MoO3 is obviously marked but differences were found with regard to the effect of additives and to the recharge efficiency, due to some structural differencesI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
