✦ Synopsis

The layered compounds, Li,,Na,,,_,V,O,, have been obtained by the ion exchange reaction of Na,.,V,O, in the molten nitrates containing Li+ and Naf ions with various ratios. Electrochemical measurements showed only two steps of the lithium insertion process of these vanadates and increase in the discharge capacity for y = 0.21. The third step, with the phase transition, has been found to be a characteristic of Li,,,V,O,.
