As. Yu et al., PREPARATION OF SODIUM MOLYBDENUM OXIDES BY A SOLUTION TECHNIQUE AND THEIR ELECTROCHEMICAL PERFORMANCE IN LITHIUM INTERCALATION, Solid state ionics, 106(1-2), 1998, pp. 11-18
Several sodium molybdenum oxides with different structures were prepar
ed by acidification of Na2MoO4 solutions with 1-3.5 N of strong acids
(HCl, HNO3) at 100 degrees C followed by heat treatment. Structural an
d compositional analyses of the oxides show that their structures were
determined by preparation conditions such as acid type and concentrat
ion, and heat-treatment temperature. The electrochemical intercalation
of lithium into these oxides was attempted using them as the positive
electrode materials for secondary lithium batteries. The results show
reversible lithium intercalation and electrochemical performance that
greatly depends on the oxide structure and composition.
