Abstract
Official abstract text for this publication.
According to one embodiment, there is provided an active material. The active material includes a composite oxide having an orthorhombic structure. The composite oxide is represented by the general formula Ti 2 (Nb 1-x Ta x ) 2 O 9 (0≦x≦1). The composite oxide has an average valence of niobium and/or tantalum of 4.95 or more.
First claim
Opening claim text (preview).
What is claimed is: 1 . Active material comprising a composite oxide having an orthorhombic structure which is represented by the general formula Ti 2 (Nb 1-x Ta x ) 2 O 9 (0≦x≦1) and has an average valence of niobium and/or tantalum of 4.95 or more. 2 . The active material according to claim 1 , further comprising: at least one selected from the group consisting of a composite oxide represented by the general formula H(Nb 1-x Ta x )TiO 5 (0≦x≦1), a composite oxide represented by the general formula Ti(Nb 1-x Ta x ) 2 O 7 (0≦x≦1), and TiO 2 . 3 . The active material according to claim 1 , wherein the composite oxide having an orthorhombic structure has a symmetry belonging to the space group Pnmmm or Pn2 1 m. 4 . A nonaqueous electrolyte battery comprising a positive electrode; a negative electrode comprising the active material according to claim 1 ; and a nonaqueous electrolyte. 5 . A battery pack comprising the nonaqueous electrolyte battery according to claim 4 . 6 . The battery pack according to claim 5 , further comprising a protective circuit which configured to detect a voltage of the nonaqueous electrolyte battery. 7 . A battery pack comprising a plurality of nonaqueous electrolyte batteries, each of the plurality of nonaqueous electrolyte batteries comprising: a positive electrode; a negative electrode comprising the active material according to claim 1 ; and a nonaqueous electrolyte, wherein the plurality of nonaqueous electrolyte batteries are electrically connected to each other in series and/or parallel.
