| 20090246633 | MANUFACTURING METHOD OF ELECTRODE MATERIAL, AND ELECTRIC STORAGE DEVICE - 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. | 10-01-2009 |
