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. The production method according to the present invention can be linked to a conventional production method in which an ammonium metavanadate can be formed in the course of the method, whereby the present invention can smoothly be embodied.

摘要： A physical property of a suspension into which plural lithium materials, such as a lithium sulfide, lithium hydroxide, etc., and a vanadium material are dissolved is adjusted by using the plural lithium materials. According to the adjustment, the valence of pentavalent vanadium ions is controlled to be a desired ratio. A material having the obtained layered crystal particles and an amorphous part is used as a starting material, and this material is subject to a heat treatment. With this process, the layered crystal particles grow, while the amorphous part is decreased. Consequently, it is confirmed that the rate of capacity deterioration is improved.
