PROBLEM TO BE SOLVED: To provide: a nonaqueous electrolyte battery which is superior in charge/discharge cycle life performance under a high-temperature environment; an assembled battery including such nonaqueous electrolyte battery; and a battery pack.SOLUTION: A nonaqueous electrolyte battery comprising a container 2, a nonaqueous electrolyte, a positive electrode 3, and a negative electrode 4 is provided according to an embodiment. The positive electrode 3 includes an Al-containing positive electrode collector 3a, and a positive electrode active material-containing layer 3b formed on the positive electrode collector 3a. The negative electrode 4 includes an Al-containing negative electrode current collector 4a, and a negative electrode active material-containing layer 4b formed on the negative electrode current collector 4a. The negative electrode active material-containing layer 4b includes titanium-containing oxide particles whose secondary particles have an average particle diameter of over 5 μm. The nonaqueous electrolyte battery satisfies the following expression (1): Lp<Ln (1), where Lp represents a thickness of the positive electrode collector 3a, and Ln represents a thickness of the negative electrode current collector 4a.SELECTED DRAWING: Figure 1 |
