super(7)Li-NMR of well-graphitized vapor-grown carbon fibers and natural graphite negative electrodes of rechargeable lithium-ion batteries

Lithium intercalation of natural graphite and well-graphitized vapor-grown carbon fibers has been investigated by solid-state super(7)Li-NMR and by cyclic voltammetry. Chemical shift of super(7)Li in Li-graphite intercalation compounds (Li-GICs) of natural graphite occurs in two regions, >40 and
