Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A titanium oxide compound having a crystal structure of a monoclinic titanium dioxide and satisfying the following equation (I): d 001 ≧6.223 Å (I) wherein d 001 is the spacing of the (001) plane which is measured by the powder X-ray diffraction method using a Cu—Kα radiation source, and wherein the titanium oxide compound has a crystal structure which belongs to the space group C2/m, the titanium oxide compound is suitable as an active material i…
