  "textContent": "An electrode material uses, as an active material, sodium vanadium oxide represented by NaVO(0 < x < 0.33) and having a crystal phase of a stoichiometric composition of NaVOor NaVO. As a result, together with improving battery capacity by employing a composition in which Na is made to be deficient, satisfactory cycle characteristics can be maintained due to the presence of sodium. In addition, since an electrode material production method uses NaOH and NHVOas raw materials, the electrode material of the present invention can be efficiently produced with heat treatment at a comparatively low temperature.",
