Abstract
According to one embodiment, a nonaqueous electrolyte battery including a positive electrode and a negative electrode is provided. The positive electrode includes LiNiMOwherein M is a metal element including Mn, and x is within a range of 0.5≦x≦1. The negative electrode includes graphitized material particles and a layer. The graphitized material particles have an interplanar spacing of (002), according to an X-ray diffraction method, of 0.337 nm or less. The layer includes a titanium-containing oxide. The layer covers at least a part of a surface of the graphitized material particles.
