Abstract

Official abstract text for this publication.

A negative electrode active material according to one embodiment includes a titanium oxide compound having a crystal structure of monoclinic system titanium dioxide. The titanium oxide compound is modified by at least one kind of ion selected from the group consisting of an alkali metal cation, an alkali earth metal cation, a transition metal cation, a sulfide ion, a sulfuric acid ion and a chloride ion.

First claim

Opening claim text (preview).

What is claimed is: 1. A negative electrode active material comprising a titanium oxide compound having a crystal structure of monoclinic system titanium dioxide, wherein the titanium oxide compound has solid acid points on a surface thereof; at least one kind of ion selected from the group consisting of Na + , K + , Mg 2+ , Ca 2+ , Cu 2+ , S 2− , SO 4 2− and Cl − exists on the surface of the titanium oxide compound; the ion is bound to the solid acid points to make the soli…
