摘要： According to one embodiment, a negative electrode active material for nonaqueous electrolyte battery includes a titanium oxide compound having a crystal structure of monoclinic titanium dioxide. When a monoclinic titanium dioxide is used as the active material, the effective capacity is significantly lower than the theoretical capacity though the theoretical capacity was about 330 mAh/g. The invention comprises a titanium oxide compound which has a crystal structure of monoclinic titanium dioxide and a (001) plane spacing of 6.22 Å or more in the powder X-ray diffraction method using a Cu-Kα radiation source, thereby making an attempt to improve effective capacity.

摘要： According to one embodiment, a non-aqueous electrolyte battery includes an outer case, a positive electrode housed in the outer case and containing a positive electrode active material, a negative electrode housed in the outer case and containing a monoclinic crystal β-type titanium composite oxide, and a non-aqueous electrolyte filled in the outer case. An absolute value of a gradient of a potential of the negative electrode is larger than that of the positive electrode. Wherein, each of the gradients of a potential of the negative and positive electrodes is found from variations in potential which come at the state of full charge on an open-circuit potential curve drawn from potentials of the positive electrode and the negative electrode.
