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

摘要

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