Some non-stoichiometric Mo oxides have been tested as cathodes for primary Li cells.

Abstract
Some non-stoichiometric Mo oxides have been tested as cathodes for primary Li cells. Their performance has been evaluated as a function of current density, electrolyte, temperature, cathode porosity and formulation. Specific capacities exceeding 0.4·Ah g−1 could be reached at low rates. As found with MoO3, these oxides give rise to the formation of ternary phases of the type LimyMomO3m−1. Li+ insertion in the lattices allows structure retention for Li/Mo ratios lower than 0.7–0.8, whereas higher Li+ contents result in the appearance of new phases.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
