Abstract

The invention discloses a method for preparing copper molybdate nanoparticles as a lithium ion battery negative electrode material. The copper molybdate nanoparticles are synthesized with cupric acetate dihydrate and ammonium molybdate tetrahydrate as raw materials and a sodium hydroxide aqueous solution as a solvent by one-step hydrothermal synthesis. The preparation method is simple to operate; the reaction time can be shortened significantly and the reaction temperature is reduced by adjusting the solution environment; the preparation process has low cost and can be used for industrialized scale production. The copper molybdate nanoparticles prepared by the method have the advantages of high purity and high crystallinity, and has good electrochemical activity and cycle performance when used as the lithium ion battery negative electrode material, and provides a certain theoretical basis and practical experience for application of copper molybdate nano materials in energy storage and other fields.

Description

[0001] 【Technical field】 [0002] The invention belongs to the intersecting field of inorganic nanometer materials and energy materials, and relates to a copper molybdate nanoparticle and a preparation method and application thereof. [0003] 【Background technique】 [0004] Metal molybdate nanomaterials have unique structures, electrical properties and catalytic properties. They are not only used in the fields of humidity sensing, optics, phosphors, mildew suppression and antibacterial, but also in seawater corrosion inhibition, photocatalytic degradation of wastewater, electrode materials, pigments, etc. And negative thermal expansion materials and other fields also have potential applications. [0005] Copper-based molybdates have attracted more attention because of their unique structure and physicochemical properties. For example, the Chinese invention patent CN201110347508.5 discloses the preparation of radial copper molybdate microspheres (Cu 3 Mo 2 o 9 ), the reactio...
