摘要：

Li-7 solid nuclear magnetic resonance (NMR) spectra of the fully-charged disordered carbon(H/C atomic ratio = 0.3) were measured at various temperatures. One band at 17.8 ppm was observed at room temperature and even at low temperature, only one band at 4.8 ppm was observed. Based on our theoretical calculations, the mechanism of Li storage in the disordered carbon is discussed.
