Abstract:
An active material with a sufficient cycle characteristic and a process for its production are provided. According to the process for production of an active material of this invention, an aqueous solution containing a metal fluorocomplex is contacted with a metal oxide to form a surface-modified layer on the surface of the metal oxide. The active material of the invention comprises a core section made of a metal oxide and a surface-modified layer covering the core section, wherein the surface-modified layer is an oxide containing a metal present in the core section and a metal not present in the core section.
