Nonaqueous electrolyte battery electrode, nonaqueous electrolyte battery, and battery pack

Abstract

A nonaqueous electrolyte battery electrode according to an embodiment includes a current collector and a mixed layer formed on one surface or both surfaces of the current collector. The mixed layer includes an active material and a binding agent. The ratio I2/I1 of the highest peak intensity I2 in peaks appearing in the wavelength range of 1400 to 1480 cm−1 to the highest peak intensity I1 in peaks appearing in the wavelength range of 2200 to 2280 cm−1 is 10 or more and 20 or less in an infrared absorption spectrum measured according to a total reflection measurement method. Alternatively, in the mixed layer, the ratio I3/I2 of the highest peak intensity I3 in peaks appearing in the wavelength range of 1650 to 1850 cm−1 to the highest peak intensity I2 in peaks appearing in the wavelength range of 1400 to 1480 cm−1 is 0.1 or more and 0.8 or less in an infrared absorption spectrum measured according to a total reflection measurement method.
