Original Abstract Submitted
An electrochemical device includes a positive electrode, a negative electrode, and an electrolyte having lithium ion conductivity. The negative electrode includes a negative current collector and a negative electrode material layer supported on the negative current collector. The negative electrode material layer contains a negative electrode active material capable of being reversibly doped with lithium ions. The negative electrode active material contains a carbon material. The negative electrode material layer includes a coating region on a surface layer portion of the negative electrode material layer. An O1s spectrum for the coating region has a peak in a range from 530 eV to 534 eV of a binding energy in an O1s spectrum. An intensity of the peak in the O1s spectrum increases as a measuring position changes from a surface layer of the coating region toward the inside of the coating region.
