    摘要： The electrode material according to the present invention has a crystal phase in the form of a lattice containing lithium vanadium oxide, such as Li0.3V2O5 with a primary particle diameter of 10 nm or more and 200 nm or less, wherein lithium is arranged in the lattice. Accordingly, when the electrode material is used as the positive electrode material, especially in the crystallized state containing an amorphous glass composition such as phosphor, lithium, antimony (or iron), a high battery capacity can be obtained. Further, even if the charging and discharging are repeated, the crystal structure is difficult to be collapsed, whereby the cycle characteristic is enhanced.

    摘要： When a layered crystal material of vanadium pentoxide that can be used as a positive electrode active material is manufactured, a sulfur-containing organic material is not used as a raw material in the present invention. Therefore, uncertain adhesion of the sulfur-containing organic material to the layered crystal material is eliminated. The property of the suspension containing a vanadium compound and plural lithium compounds such as lithium sulfide and lithium hydroxide is adjusted by using these lithium compounds. By this adjustment, the pentavalence of the vanadium ions is controlled to be a desired ratio. Consequently, an active material having reproducibility can be manufactured. First discharge energy of a lithium ion secondary battery using the active material can be enhanced.

    摘要： An ammonium metavanadate is heat-treated to 500° C. or less at a predetermined rate of temperature rise, whereby a microcrystal particle of a vanadium pentoxide can be formed. According to the production method described above, a crystal of a nano-vanadium having a layer length of 100 nm or less can be formed. The nano-vanadium formed by the production method described above can effectively be used for an electrode of an electric storage device such as a battery.
