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 I/Iof the highest peak intensity Iin peaks appearing in the wavelength range of 1400 to 1480 cmto the highest peak intensity Iin peaks appearing in the wavelength range of 2200 to 2280 cmis 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 I/Iof the highest peak intensity Iin peaks appearing in the wavelength range of 1650 to 1850 cmto the highest peak intensity Iin peaks appearing in the wavelength range of 1400 to 1480 cmis 0.1 or more and 0.8 or less in an infrared absorption spectrum measured according to a total reflection measurement method.
