摘要

According to one embodiment, an active material containing a niobium titanium composite oxide is provided. The niobium titanium composite oxide has average composition represented by LiyNb2+xTi1?xO7+0.5x (0≤x≤0.5, 0≤y≤5.5). The niobium titanium composite oxide satisfies peak intensity ratios represented by the following formulae (1) to (3): 0.05≤(B/A)≤0.7??(1) 0.01≤(C/A)≤0.2??(2) 0≤(D/A)≤0.1??(3).

說明書

A nonaqueous electrolyte battery according to a second embodiment includes a positive electrode, a negative electrode containing the active material according to the first embodiment, and a nonaqueous electrolyte. The nonaqueous electrolyte battery further includes a separator disposed between the positive electrode and the negative electrode; and a case which houses the positive and negative electrodes, the separator, and the nonaqueous electrolyte.

Hereinafter, the positive electrode, the negative electrode, the nonaqueous electrolyte, the separator, and the case will be described in detail.

1) Negative Electrode

The negative electrode includes a current collector and a negative electrode active material containing layer (negative electrode material layer). The negative electrode active material containing layer is formed on one side or both sides of the collector. The layer includes the active material and arbitrarily includes the conductive agent and the binder.
