    摘要: The invention relates to a method of producing a crystalline lithium/vanadium mixed oxide powder having formula Li1+xV3O8, wherein x is between 0 and 0.2. The inventive method comprises the following steps: formation of an aqueous suspension from a NH4VO3 paste and lithium hydroxide monohydrate powder; continuous dehydration of the aforementioned suspension in a stream of hot gas at a temperature of between 200 and 600 °C in order to form a dry powder of a precursor, having a particle size of between 10 and 100 µm; and calcination of said precursor at a temperature of between 380 and 580 °C into a crystalline powder Li1+xV3O8. The product thus obtained is intended, in particular, for the production of lithium rechargeable batteries and battery electrodes.
