MANUFACTURING METHOD OF ELECTRODE MATERIAL, ELECTRODE MATERIAL, AND NON-AQUEOUS LITHIUM ION SECONDARY BATTERY

摘要

An electrode material is provided to suppress the disintegration of the crystalline structure and to secure the coming in and out of the lithium ion by making the layer length of a crystalline structure of a vanadium oxide-based material short. A manufacturing method of electrode material uses a vanadium oxide having the layered crystal capable of doping a lithium ion as an active material and comprises a doping process of doping an inter-layer securing member between the layers of the layered crystal. The doping process of the inter-layer securing member is performed before a process of doping the lithium ion. The inter-layer securing member is a cation having big ion radius except a lithium ion.
