The C/P atomic ratio derived from the XPS intensities decreases upon increasing the ball milling time, from 2.01 to 1.25 for the two P/C-composite materials ball milled 2 and 54 h, respectively. The C/P value after 54 h of ball milling is in close agreement with the EDS value and the expected 1.1 molar ratio.
