摘要：

(7)Li solid-state nuclear magnetic resonance (NMR) is employed to investigate the mechanism of electrochemical lithium-intercalation in various carbon materials. Multiple resonance line shapes observed in fully lithiated carbons indicate that several intercalant sites exist under distinct spin-interaction environment, and they are substantially dependent upon physical nature of host structure. The temperature dependence of resonance spectra in disordered carbons prepared at relatively low carbonization temperature considerably differs from that observed in lithiated carbons with graphite structure.
