摘要:
According to one embodiment, there is provided an electrode for a nonaqueous electrolyte battery. The electrode includes an active material layer. The active material layer includes a monoclinic β-type titanium composite oxide. When the electrode is subjected to an X-ray diffraction measurement using a Cu-Kα ray source, a ratio of a reflection intensity I(020) of a peak derived from a plane (020) of a crystal of the monoclinic β-type titanium composite oxide to a reflection intensity I(001) of a peak derived from a plane (001) of the crystal of the monoclinic β-type titanium composite oxide being in the range from 0.6 to 1.2.
