7Li-NMR study of lithium charged phosphorus-doped disordered carbon

7Li high resolution nuclear magnetic resonance (NMR) measurements at various temperatures in fully-charged phosphorusdoped disordered carbon material have been performed. It was found that a broad line at 69.5 ppmand a relatively sharp line in near 15.0 ppm were observed at room temperature and four lines at 20.8, 74.6, 144.6 and 199.0 ppm were observed at low temperature. The mechanism of Li storage in P-doped disordered carbon is discussed.
