Patent number: 8945773Abstract: 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 ? or more in the powder X-ray diffraction method using a Cu—K? radiation source, thereby making an attempt to improve effective capacity.Type: GrantFiled: September 21, 2011Date of Patent: February 3, 2015Assignee: Kabushiki Kaisha ToshibaInventors: Yasuhiro Harada, Norio Takami, Hiroki Inagaki, Keigo Hoshina
