A non-aqueous electrolyte battery including a negative electrode including metal lithium or a lithium alloy as a negative electrode active material, a positive electrode including a fluorinated graphite as a positive electrode active material, a separator provided between the positive electrode and the negative electrode, and a non-aqueous electrolyte. The concentration ratio [F]/[C] of fluorine atoms to carbon atoms on the surface of the fluorinated graphite is 1.0 or more and less than 1.8. This improves the large-current discharge characteristics particularly in a low temperature environment.
