Abstract:
According to one embodiment, there is provided a nonaqueous electrolyte battery. The nonaqueous electrolyte battery includes a positive electrode, a negative electrode, and a nonaqueous electrolyte. The positive electrode includes a positive current collector and a positive electrode material layer formed on the positive electrode current collector. The positive electrode material layer includes a positive electrode active material and a first conductive agent. In a mapping image for the positive electrode material layer, a ratio of an occupancy area of the first conductive agent to an occupancy area of the positive electrode active material is from 1.5 to 5.
